Earth Hour throughout the
World - Make it Happen Here
by Drs. Robert and Sonia Vogl
This month,
participate in a symbolic event that will remind us of how much energy we use
unnecessarily: Earth Hour.
World Wildlife,
partnering with HP, is sponsoring this awareness raiser. On Saturday, March 29, from 8:00
- 9:00 p.m., people throughout the world will turn off lights and electrical appliances to
experience an hour of night. Families will sit near the fireplace, light candles, read
books, stargaze and just talk with each other. In addition to being a consciousness raiser
the hour will allow individuals to reconnect without modern electronic distractions.
Earth Hour
provides an opportunity for people to recognize that we all contribute to global warming
but that each of us can have a positive impact. Turning off the lights for only one of the
8,760 hours of the year will show us that its possible to readjust our lifestyles.
Small sacrifices such as this could have an important effect on controlling the adverse
effects of climate change.
Evidence of
global warming is everywhere, from melting arctic and antarctic ice through changing
ecosystems to species extinction. Reducing CO2 emissions is the most immediate step
needed. Reducing excess lighting is a good start.
In March, 2007,
Sydney, Australia, went dark for an hour and saved twice the electricity expected. So far,
fourteen cities have pledged to go dark. Chicago is considered the flagship of
four in the U.S. Mayor Richard M. Daley claims that An important part of Chicagos
efforts to be the most environmentally friendly city in the world is understanding the
effects of climate change in our city. Earth Hour should help bring about that
understanding.
In their
service area, ComEd is co-sponsoring Earth Hour. They invite all of their customers to
participate. They also urge them to replace incandescent light bulbs with ENERGY
STAR qualified compact fluorescent lights (CFLs) and pledge to reduce their energy
consumption in 2008. They assure their customers that those lights necessary for
public safety will remain on and remind them to be careful with candles, especially if
children are present. ComEd is one the the Illinois Renewable Energy and Sustainable
Lifestyle Fairs major sponsors.
A related
organization, the International Dark Sky Society, also supports Earth Hour, calling it
Lights Out America. The IDSS wants people to have the opportunity to see the night skies
and the stars, celebrated by poets as the greatest glory of Creation. Their mission is
To preserve and protect the nighttime environment and our heritage of dark skies
through quality outdoor lighting. Those interested in learning more can visit the
IDSS booth at the Fair August 9 and 10.
Earth Hour is
symbolic. It alone will not make a difference. But the awareness it raises has the promise
of changing peoples perceptions of their energy uses versus their real needs along
with changes they can make in their behavior to help the Earth.
Urge your city
to participate in Earth Hour. Even if it doesnt, organize your own friends and
families. Enjoy an hour together in the natural dark of night, considering and planning
how you can do your part.
One-Watt-HouseTM
By Drs.
Robert and Sonia Vogl
Its the house with the blue
roof. Color may be the easy way to locate
Victor and Polly Zaderejs house, but its not the only unusual feature of the new home nearing completion southeast of Oregon,
IL.
Built on principles adapted from the
German Passivhaus, the home is extremely
energy efficient, using about 1/10 the energy for heating as a conventional house, but costing only about 1/10 more to build.
It is referred to by Marko Spiegel as the
One-Watt-HouseTM, based on its consuming
only one watt of heating energy per square foot as opposed to the ten watts used in conventional buildings.
We first became aware of the Passivhaus
movement at the 2006 Renewable Energy and
Sustainable Lifestyle fair when Dr. Bernd Steinmuller made his keynote presentation on energy efficiency in buildings. He
stressed heavy insulation to save money on heating
bills and cut CO2 releases. Although Germany is a
world leader in efficient housing with most of the
worlds 10,000 passive houses in Europe, Steinmuller feels that German buildings could be still more efficient as could those in
the U.S.
Zaderej and his friend and colleague,
Spiegel, have known of extreme energy efficiency for several years, traveling to Germany frequently to be updated on new developments. After studying the principles
and examining houses, the two engineers decided
to put their knowledge to work in an actual home.
They located materials as similar to those used in Germany
as they could find in North America. Their searches were wide - the doors and windows were made in Canada.
The exterior of the home is heavily
insulated with R 40 insulation in the walls and R
50 in the ceilings. Insulation is not an afterthought - it is an integral part of the walls and roof, constructed of
SIPs (structurally integrated panels) formed by
five inches of foam insulation sandwiched between
two 5/8 inch thick panels of chip board. Posts and beams add strength to the exterior. ICFs (insulated
concrete forms) provide an R rating of 20 under the
foundation.
On winter days large south facing double
glazed hard coat low E windows with a U rating of
33 collect the suns heat which is stored in the concrete floor of the lower level for release during the night.
North, west and east windows are triple glazed with
a U rating of 24.
One of the two 120 gallon superinsulated
all plastic Marathon water heaters provides for
domestic use. Between 80 and 90 percent of
shower water heat is returned to the water heater.
The second sends hot water to the air furnace which
then circulates the heat. The water heaters are on
demand metering with timers set to turn on at night.
An air to air heat exchanger with a whole
house ventilator removes stale air from the
kitchen, bathrooms and laundry. It also recovers over
50 percent of the heat from outgoing air. A space beneath the steel roof collects warm air which is blown into the stone wall
in the office. South roof overhangs protect the
interior from the summer suns heat.
An earth tube brings air with the
grounds steady temperature into what the
engineers refer to as an earth room where it is stored for circulation throughout the house. In winter, the earth is warmer
than the outdoor air; in summer, it is cooler,
providing relief from temperature swings.
This winter, Zaderej and Spiegel invited
us to a reading - of a thermometer. It read 68o at
nine p.m. on a below zero night. The furnace has
not run since late February. Ten 200 watt light bulbs left on overnight maintain a comfortable level even when the outdoor
temperature is below freezing.
Contractor Rick McCanse explains that
thermal mass provides thermal lag. Although he
built the house, McCanse admits, Its pretty amazing.
The Zaderejs are now planning their
landscaping with an emphasis on the large lawn.
They recently asked us to advise them on native dry prairie grasses and forbs which need almost no care, look beautiful, and
remain a respectable short height. Their passion
for passive will extend to the yard so theres
no mowing!
A Grand
Solar Plan
by
Drs. Robert and Sonia Vogl
The amount of sunlight striking the earth in 40 minutes is equivalent
to the total energy consumed worldwide in 2006. Despite its abundance
and its economic and environmental benefits, only 0.2 percent of our
countrys electricity came from solar energy in 2004.
In the December 16, 2007, issue of Scientific America, Zweibel, Mason
and Pthenakes proposed to dramatically increase the production of
electricity from the sun. They plan to obtain 69 percent of our
electrical needs and 35 percent of our total energy needs from solar
energy by 2050.
With government support, they expect to produce photovoltaic and
concentrated solar energy at a cost of $0.06/kWh by 2020. To stimulate
large scale production and improve module efficiency, they seek to
install 1.5 GW of solar electric and 1.5 GW of concentrated solar power
over the next five years. Over the following five years the goal for
each source would be 5 GW. By 2020 production would approach 84 GW. By
2050 federal funds would no longer be necessary.
The elaborate solar system would be built in the dry, sunny Southwest.
Electricity would be shipped nationwide over new DC power lines. Ten
percent of the total solar power would be placed on existing rooftops
throughout the country.
For photovoltaic production they envision using the least expensive
thin-film modules such as those made of cadmium telluride which are 10
percent efficient. They would compress air and force it into
underground storage for continuous electric production. Used in
combination with natural gas generators, compressed air can cut natural
gas consumption by 60 percent.
The concentrated solar power system would consist of long, metallic
mirrors which focus sunlight on liquid filled pipes. The heated fluid
is carried to a heat exchanger where steam is used to generate
electricity. The pipes are also linked to a large, insulated tank
filled with molten salt which retains the heat to produce electricity
when the sun is unavailable. The concentrated solar power system would
provide 20 percent of the entire systems electricity.
The overall plan calls for $420 billion in federal subsidies at a rate
of around $10 billion per year, less than annual farm subsidies. To pay
for the program a carbon tax of $0.005/kWh would be added to our
electric bills. This is 1/2 to 1/4 the projected cost of capturing and
storing carbon from new coal facilities.
The solar plants would eliminate the need for 300 large scale coal
plants and 300 large natural gas plants. With an expected lifetime of
30 years, substantial clean energy benefits would accrue.
It is a bold plan which makes explicit the need for substantial,
sustained funding to decrease the cost of solar power. But it begs the
question of whether a decentralized approach could achieve similar
goals. If each state received $200 million a year to support solar
energy it would provide a dramatic increase in Illinois rebates and
grants programs for renewables which never exceeded $5 million a year.
Solar installations on existing rooftops across the nation are
increasing dramatically; Illinois has plenty of available roofs.
CFLs
- a Step in the Right Direction
by Drs. Robert and Sonia Vogl
Once again, Commonwealth Edison is offering residential customers an opportunity to buy up
to one million Energy Star rated compact fluorescent light bulbs (CFLs) at a substantial
discount. The bulbs are available in 350 retail outlets across northern Illinois. They use
1/4 the energy of a comparable incandescent bulb and are expected to last 10 times longer.
According to ComEd, the savings from last years CFL program was equivalent to the
energy consumption of 8200 average northern Illinois homes at a savings of $35 over the
life of each bulb.
An added twist this year is the introduction of a pilot CFL recycling program in
cooperation with Ace Hardware Stores and the Illinois EPA. CFLs contain a small amount of
mercury which can be captured, processed and sold. Glass and aluminum in the bulbs can
also be captured, processed and sold. Used bulbs returned to some 150 Ace Hardware Stores
will be collected and taken to an appropriate recycling center approved of by IEPA.
While at the recent press conference at Bobs Ace Hardware Store, we shared the story
with an owner regarding how Bobs Ace became the first store in Rockford to stock
CFLs. At the time the bulbs were very expensive and only available though catalogues.
Students in an energy conservation class decided Bobs was likely to be willing to
offer the bulbs for sale. The class decided to encourage the store to carry the bulbs and
purchase at least one each. Part of the strategy included students calling the store
on successive days and asking the manager if they carried CFLs. When the third student
called, the manager indicated he had been getting quite a few calls recently about the
bulbs and would look into stocking them. Within a few weeks the bulbs were in the store
and have been available there ever since.
The simple step of replacing incandescent bulbs with CFLs is one of the fastest ways to
cut carbon emissions. It is also becoming very popular. Wal-Mart intends to double
its sales of CFLs during the next year. Citizens in countries around the world are calling
on units of government to start using CFLs in all their buildings. As citizens and
taxpayers we have the right to expect those who operate our public buildings to make
effective use of energy saving options. Some public minded citizens might even consider
buying an extra CFL and donating it to a needy public building.
A ban the incandescent bulb movement is starting to take root. Last spring Australia
announced it would phase out incandescents by 2010. A few months later Canada announced it
would phase out by 2012. A 2012 deadline has also been introduced in California while Russia,
New Zealand and India are considering similar bans.
Lester Brown estimates that a ban on incandescent bulb sales in the United States would
cut energy demand equal to the output of 80 coal fired power plants. Rather than building
more coal fired power plants as envisioned by energy supply advocates, implementing energy
efficiency programs can substantially reduce our consumption. According to many estimates
we could cut our energy demand in half by widespread implementation of energy efficiency.
According to a U.S. government calculation, the energy saved over the lifetime of one 24
watt CFL is equivalent to energy used driving a Prius from New York to San Francisco.
While the car analogy helps convey the potential of energy savings, if taken literally it
suggests we can use our saved energy on another form of energy consumption.
The energy party is over. It is time to dramatically cut our consumption. Energy reformers
have called for at least a 50 percent reduction by 2050 to avoid the worst effects of
global warming. We have the knowledge and technology to achieve energy reductions of this
magnitude, but have yet to develop the political will to make it happen.
Buy some compact fluorescent bulbs. Install them at home; give some to your friends and
neighbors; donate some to a publicly owned facility. Make the switch today.
The
Long Emergency - Is this It?
by Drs. Robert and Sonia Vogl
James Kuntsler has called the evolving energy situation the long emergency. In
Kuntslers view, the days of plentiful, low cost energy supplies are over and we will
have to redesign our communities and adjust our lifestyles to adjust to the evolving
situation. Others sharing his view call for rebuilding local economies around using less
energy, improving mass transit and growing more food locally. The sooner a community
initiates serious efforts to reorganize their local economy around dwindling and costly
energy supplies, the more successful they are likely to be.
In contrast, oil interests ran a week of ads in The Wall Street Journal proclaiming that
peak oil is premature and plentiful supplies await appropriate government action. They
advocate more research, adoption of new energy technologies and supportive government
policies to ensure plentiful supplies. They accept higher prices and reflect a business as
usual approach.
In the meantime we are left to adjust to the dramatically higher cost of electricity. We
have received phone calls and emails asking for advice on what individuals who heat with
electricity can do to lessen their costs. Integral to the all electric building strategy
was high insulation levels. Some had as much as a foot of cellulose insulation above the
top ceiling level, providing an R 40 rating. If space is available between the roof and
ceiling, more insulation can be added.
Electric homes may not have high levels of insulation in the walls. If the outer wall is
brick there may not be space to add insulation. It the house has standard siding an inch
of foam insulation could be added and new siding placed over it. In new construction R 25
insulation performs very well.
If the home has a basement, insulation could be added either on the outside or inside of
the wall. R 11 walls are common although an R 20 level should be considered.
If a vapor barrier already exists, add barrier free insulation. Care must be taken to not
have water vapor condense within the insulation. It will decrease the effectiveness of the
insulation and may give rise to mold problems. Before adding any insulation, discuss plans
with an insulation contractor or an energy rater.
Consider having a new heating system installed. If a whole house unit is desired consider
a very high efficiency natural gas furnace. Also check into a ground source heat pump.
While it still relies on electricity to work pumps and motors, electricity is not used to
produce heat but rather to capture and concentrate the grounds heat.
As discussed in previous columns, rooms might be closed off in winter with only one or two
heated to a more comfortable level. A propane heating unit could be installed in the wall
of a room to provide supplemental heat. Corn, pellet and wood burning stoves and furnaces
also provide supplemental heat. (note: Be sure to check with your
insurance agent and local authorities to see what is necessary to meet safety codes in
your area.)
Another choice would be to have a solar hot water system installed to provide supplemental
heat. However, since the sun does not always shine, backup energy is still needed. In this
case the existing electric resistance heating system would help.
The article by Roland Wolff describes how a family upgraded an old, energy guzzling,
drafty farm house into a very energy efficient home. Home Power Magazine and Home Energy
Magazine have articles addressing retrofitting homes or building for energy efficiency and
are excellent sources for additional ideas.
If we have entered the long emergency, conservation and efficiency are the most effective
ways to adjust.
A Tale of Two Farmhouses
By Roland and Birgit Wolff
Photos to be posted
The home of Roland and Birgit Wolff in the northwoods of Wisconsin, before renovations
(above) and after (below).
Actually, one house, with
two incarnations...
Ah, northwestern Wisconsin. Lake Superior. Pristine forests and rivers. This is the place
where our hearts have always been, and to which we were happy to retire in 2002 after 28
years of job-enforced exile in Tennessee and Colorado. But we knew there was also another
thing waiting for us up here: WINTER.
In planning our move to the northwoods, one of our top questions was whether to build or
to move into and renovate the 110-year-old farmhouse on the property. It quickly became
clear that our choice had to be the latter, hands down. For the more we thought about it,
the more we realized how much we had grown to love that old house over the years when
wed come up every summerand even a couple times in winterto play. But
our love, in this case, was not blind, for we knew wed have some hard work ahead of
us making the place both safe and four-season comfortable. Some of the old buildings
character and charm we decided to leave as is, like the fact that theres not a right
angle to the place, which makes any repairs or building projects really fascinating. On
the other hand, there were some things we decided to bring up to date right away, for
safetys sake, like the stairs leading to the second floor. As in all the original
buildings here, those old stairs were steep as a ladder and so narrow you had to come down
feet sideways. They had broken neck and lawsuit written all over them, and bringing them
up to code was one of our very first jobs. With that done, our thoughts turned to the
cold, dark months to come, and the need to make the place really winterproof. That would
mean several major projects.
In the old days, nobody used insulation up here when they built, so the only thing between
our living room couch and the frigid winter air was a layer of half-inch clapboard over
some intermittent pine sheathing on the outside. Plus some ancient Swedish newspapers that
the original owners had stuffed into the walls to keep the wind outwhich, of course,
didnt work. In fact, sitting on that couch in winter, youd swear that those
original walls (and newspapers) actually somehow managed to intensify the outside cold
before transmitting it into the
house. Something had to be done about the walls.
Another problem was the original windows. When you walk around your living room with a
candle, and it blows out as you go past a closed window, something needs to be done. And
not just with a view to comfort, for those old single-panes would get so frosted up on the
inside during cold weather, you couldnt see out. This made you feel locked in, as
well as cut off from what you knew was a beautiful winter landscape out there very much
worth viewing.
For the walls, we A) blew in fiberglass insulation from the outside; B) put 1-inch
insulation board, well taped at the seams, on top of the old clapboard sidingwhich
we decided to leave on for an additional air space; and C) put a rough-cut 1 by 8 pine
siding, well caulked, over the insulation board. All this, plus pine paneling inside over
the original lathe-and-plaster, gives us outside walls that average 9 inches of raw
insulating, wind-defying power.
The old windows we replaced with thermopane, and made sure the new ones were well sealed
and caulked. No more blown-out candle syndrome for us.
There was also the old asphalt roof, on top of which we put 1-inch-thick nailers, with
insulation board between them, and steel roofing on top of everything.
The result of all this is a house as cozy and warm as any weve ever lived in
anywhere. We heat for the most part with a small but potent Quadrafire 2100 Millennium
wood-burning stove (hard maple firewood only), with room-by-room electric baseboard
backups, which we use only in the very coldest weather, and then rarely. With its
insulation and tightness, the house is also as good as air-conditioned: One day during
last Julys heat wave, we recorded 98 degrees outside and 72 in the living room. And
the insulation and windows, combined with an inside finishing job, have transformed the
grim old attic from a wintertime freezer and a summertime bat-infested hellhole into a
living space fully as comfortable as the rest of the house. Not to mention the fact (which
we were happy to discover by accident, afterward) that a well-insulated second floor/attic
makes the first floor, where we do most of our living, ever so much easier to keep warm in
winter and cool in summer.
Were happy to say that life up here is fulfilling all our fondest expectations. And
even when things get a bit chilly in winter, or hot in summer, we have our cozy, friendly
old house to be happy and comfortable in. Plus, theres the equally heartwarming
impact on the energy budget: Our electric bill averages $100 a month, which includes the
house, barn, outbuildings, chickens, sheep, and several freezers; and we spend $200 a year
on firewoodcut, split and delivered. Plus, one more bonus: the wood stove even has a
nice glass door to view the flickering, energy-efficient flames through on a gold
winters night!
Roland and Birgit Wolff live on their old farmstead just south of Lake Superior in Bayfield
County, Wis., and are loving every minute and every season of it.

Growing a Sustainable Energy Future
by Drs. Robert & Sonia Vogl
As
global energy supplies dwindle and prices rise, increased competition for resources
increases the likelihood of armed conflicts. The need to address climate change increases
the importance of efficiency and renewable energy.
Much
more is happening with renewable energy in Illinois than when we started writing on the
topic five years ago. Support from the Illinois Clean Energy Community Foundation, ComEd,
the Illinois Department of Commerce and Economic Opportunity and The Rock River Times has
helped nurture an energy transition.
Ethanol
and biodiesel plants, methane digesters and wind farms are large, highly visible and well
publicized. Individuals and small businesses are engaged in smaller, often overlooked
projects that enhance personal and community energy security. These include energy
efficient homes, ground source heat pumps, outdoor wood furnaces, corn and wood pellet
stoves, solar electric systems, small wind generators, solar hot water systems, water
pumping windmills and an increasing number of organic farms. Hybrid
electric cars are no longer a novelty item.
Solar
electric projects are gaining in size and scope. A 50 kW system in Sublette is the largest
one in this area. However, some substantially larger systems are appearing in other parts
of the world. Germanys
largest solar electric installation is 12 megawatts - bout 240 times as large as the
Sublette installation. A new solar park in Spain will feature a 23 MW system. China
recently announced plans to install a 100 MW system only to be outdone by an Australian
project of 154 MW. In this case size does matter as it provides the opportunity to capture
economies of scale which help reduce overall costs.
The
current cost of a 2 kW household system in Illinois is around $8 per watt. With
state rebates and federal tax credits, costs are reduced by 50 percent.
Californias
program to have 3000 MW of solar electricity by 2016 should also help lower costs. Solar
electric systems built into rubberized roofing demonstrate the benefits of integrating
solar electricity into buildings with large flat roofs such as schools, box stores,
factories and warehouses. In San Diego 25 schools already have solar electric roofs. As
the price of electricity increases in Illinois, such systems are likely to begin appearing
here.
Other
exciting ideas are emerging as well. Conserval Engineering Inc. has a new solar product
which generates both electricity and heat. The top of the unit converts solar energy into
electricity while a larger thermal panel below captures heat for building use.
These
projects fit well with the concept of developing a sustainable energy future. As fossil
fuels and uranium deposits are depleted, Dr. Ulf Bossel of Switzerland claims that only
hydro, solar, wind, ocean and geothermal installations can harvest renewable energy in a
sustainable way. With the addition of managed biomass and organic wastes, he believes
mankinds
energy needs can be met sustainably.
Dr. Hermann Scheer, a member of the German Parliament instrumental in designing their
renewable energy policies, is a solar advocate. He is concerned about fossil fuel
depletion and the environmental impacts of fossil fuel use. Scheer advocates shortening
the energy chains characteristic of our energy system. A 100 car train moving coal from Wyoming
to Illinois for use at power plants is one example. Shipping liquified natural gas nearly
9000 miles from Qatar to Mexico is another. In contrast the energy chain from a solar
panel on the roof of a building to the point of use only involves traveling a few feet.
Whether a renewable energy economy of sufficient scope will emerge in a timely manner to
power a modern society is open to debate. With the seriousness of the global energy
situation, it is crucial to continue implementing sustainable solutions.
Climate Change - The Worlds Greatest Market Failure
by Drs. Robert and Sonia Vogl
Sir Nicholas Stern, former World Bank Chief Economist commissioned by
the UK Chancellor in 2005 to review the economics of climate change,
has declared that climate change is the greatest and widest-ranging
market failure ever seen.
If we continue failing to adequately invest in controlling climate
changing gases, economic growth will be undermined, causing a loss of 5
percent to 20 percent of global GDP, similarly reducing per capita
consumption. If we start investing one percent of global GDP now we can
avoid the worst impacts. Stern views taking strong actions to limit
carbon emissions as a wise investment which will send the appropriate
market signals to overcome the prevailing market failure.
When industrialization began in the 1800s the atmosphere contained 280
ppm of CO2 equivalents. Current concentrations of 430 ppm are rising at
a rate of 2 ppm/year. To stop the increase, annual emissions must be
lowered to 80 percent below current levels. If used, existing reserves
of fossil fuels could raise greenhouse gases above 750 ppm.
If we fail to act, we will experience more extreme weather events
including major storms, tornadoes, hurricanes, coastal damage, floods,
droughts and increased brush and forest fires. These in turn cause
damage to physical infrastructures increasing the amount of money
required for their repair and replacement.
Increased storm damage causes higher insurance costs; some storm prone
areas will loose insurance protection.
The Stern review calls attention to the key role local government
officials and planners will play in responding to climate change. Four
major options relying on local conditions for reducing greenhouse gas
emissions include reducing demand for emissions-intensive goods and
services; increasing efficiency; protecting local carbon storage
capacity by preserving forests and grasslands; and switching to low
carbon technologies for power, heat and transportation.
Neither the call for action nor the recommended actions are new. What
is new is increasing scientific and public fervor to act on climate
change now. Investment banker Morgan Stanley recently announced a $3
billion plan to invest in carbon trading. Seven states in the northeast
have joined together to cap regional emissions. California has set
limits on carbon emissions. Some cities have agreed to do the same.
These actions are likely to increase pressure on Congress to enact
limits on carbon emissions, if only to resolve differences in local,
regional and state efforts.
Additional pressure to act is likely to come from the International
Panel on Climate Changes report due in January. Judging by press
releases and scientific reports published in professional journals,
signs of global climate change are increasing at a rapid rate. Since
the IPCC report summarizes scientific data gathered over the last five
years, the level of alarm is expected to rise.
While the call for action will have adverse consequences on some
interests, overall investment opportunities in energy efficiency and
renewable energy will increase. If fossil fuel use is reduced and
climate changing gases are captured, the worlds greatest market
failure will have been corrected.
A Community Approach to Energy Efficiency
by Drs. Robert and Sonia Vogl
When John Root accepted the position of running the energy rebate
program for the Muscatine, Iowa, municipal Power and Water Company, he
faced the challenge of gaining community acceptance of the need for
energy efficiency.
His strategy was to create a partnership between the utility, city, and
county and local institutions. He appealed to them to cut overhead by
implementing energy efficiency strategies and technologies in their
operations. A common response was one of disbelief as conservation was
falsely seen as virtuous but not profitable.
Even with high energy prices he finds peoples mental barriers stop
them from taking money saving actions. Some include faulty information
such as the belief that lowering the temperature at which a furnace
cuts in when no one is home causes more energy use later when raising
the setting to a comfortable level. Others include reluctance to spend
extra money today to implement efficiency measures although savings
will return the investment within two or three years and continue to
provide profit for years to come. In such cases, people tend to grasp
existing myths to justify not taking action. A plea of not having
enough money helps avoid thinking about changing behavior and spending
priorities to make the investment in efficiency.
Others barriers include a lack of current knowledge about available
energy efficient choices and the unwillingness or uncertainty of how to
obtain information. When facing a new energy efficient technology
people may be suspicious that it may not work as well as claimed. A
fear of making the wrong choice can immobilize people who then continue
with existing products or patterns.
In order to overcome these barriers, Root offers energy audits to
businesses and home owners with suggested actions and estimates of the
time it will take to recapture investments.
Replacing incandescent light bulbs with compact fluorescents bulbs is
one of the best investments home owners can make. Many small
businesses benefit from upgrading their lighting systems as well. Root
believes that energy savings should be an integral part of every
communitys economic development plan as it lowers the cost of doing
business and keeps more dollars local.
In 2005 customers in the city of 25,000 reduced their electrical
consumption by over 10 million kilowatts and saved nearly $1.5 million
with efficiency upgrades which will pay for themselves in four years.
The energy savings are equivalent to installing thirty-three 750 kW
wind generators and 1,035 five kW solar electric arrays. The investment
in efficiency was the most effective way to save money and cut
pollution.
In addition to offering a technical advisory service to customers of
the Municipal Utility, Root created an efficiency and renewable energy
program for the Muscatine Schools. He began with an energy efficiency
and renewable energy poster contest for fourth and fifth graders to
raise community awareness. He followed that with a take-home energy
audit for students which required parental assistance. This helped
alert the adults to energy savings opportunities within their homes.
Later seventh and eighth graders were encouraged to join the Solar
Sprint contest. They purchased and assembled model solar cars with
batteries and entered them in competitions to determine which vehicles
performed best. Of course, parents and grandparents became interested
in the activities.
As interest grew a high school program know as the electrathron was
added. In this program students build and race electric cars 12 feet
long and four feet wide which carry 64 pounds of batteries. Students
raise up to $4000 to secure materials needed to build each car, which
is a team activity.
Another high school program is a student organized community energy
fair. Each year the senior who submits the best 1000 word paper on
energy efficiency and renewable energy is awarded a $500 college
scholarship.
While each community is unique, there are many elements in Energize
Muscatine which could be replicated in other communities. Considering
the long term nature of our energy and climate change challenges, it is
something every community should be working on now.
This column is based on a presentation by John Root, August 13, 2006,
at the Ogle Co. Fairgrounds and on information from the Muscatine Power
and Water website.
Trusting
the Science on Global Warming
by Drs. Robert and Sonia Vogl
Our
life experiences have given us faith in the scientific process to identify health problems
and develop solutions. During our childhoods, the scourge of polio was removed from our
lives thanks to the discovery of a vaccine to prevent it. Our daughter survived meningitis
as a young child thanks to the discovery of sulfa drugs. Friends are alive today leading
productive lives because lithium manages their bipolar condition to keep them from sinking
into self destructive depression.
So
when some of the worlds leading scientific organizations reach consensus that
burning fossil fuels and cutting down the worlds forests are undermining the health
of our planet and human welfare, we give serious consideration to their findings and
recommended solutions.
Climate
change models for Illinois suggest an increase in the frequency of intense storms coupled
with an increase in droughts are likely to reduce agricultural output and adversely affect
existing ecosystems. Experience indicates our oaks will be at risk as they are shallow
rooted and severely stressed by drought.
Recently
the owner of a local tree trimming and removal service asked us why he is seeing so many
dead oaks. On one property he removed 30 dead trees from a stand of 100; all but one was
an oak. Another client reported he has lost an average of 15 oaks a year for the past few
years. A recent editorial in the Dixon paper sounded an alarm about the presence of oak
wilt in the community and called for an assessment of its extent and consideration of
appropriate action.
We
called a local certified arborist, Lant Huntley, to examine a cluster of three oaks on our
property showing signs of stress. He did not think they were suffering from oak wilt, but
for an accurate diagnosis he suggested we take samples and send them to a lab for
analysis. Aware of an increase in tree deaths, Huntley hopes to develop innoculants and
experiment to determine whether it is possible to immunize trees to selected diseases.
The
new documentary film, An Inconvenient Truth, featuring Al Gore, is an attempt to raise
public awareness regarding the planetary threat of global warming, its implications for
human welfare and the need for appropriate action now. Sir David King, the Chief
Scientific Advisor for the UK, considers global warming the worlds biggest threat
requiring immediate, sustained action.
Several
reports suggest we have about 15 years to take action to avoid the more serious
consequences of global warming. The fastest, surest, least costly response is to conserve
energy and use it efficiently. This response makes sense on its own merits even if the
human contribution to global warming proves less significant than now projected.
Unfortunately
the public continues to consume energy at an unsustainable rate and our economic and
political elite place far too little emphasis on conservation and efficiency. We need a
rapid, permanent change in our use of energy. A few years ago, California citizens quickly
cut their energy consumption nearly 15 percent in weeks in response to an energy crisis
and government leadership. Conservation and efficiency should be the backbone of our
energy reforms.
This
years energy fair will have many workshops focused on conservation and efficiency.
Here are examples: Bob Lieberman of the Illinois Commerce Commission and Hans Detweiler of
the Illinois Department of Commerce and Economic Opportunity will address the future of
efficiency and renewables in Illinois. Joe Schacter of the Environmental Law and policy Center
will explain how Illinois can derive health and economic benefits by cleaning up our cars.
Dan Persky, Advisor to Lt. Governor Pat Quinn, will Describe how the Green Government
Coordinating Council is greening Illinois.
An
exciting new approach to using the German Passive-Haus model will be the
subject of two presentations. Vic Zaderej, Marko Spiegel and Rick McCanse, who are
building such a house near Oregon, will explain how a person can heat a home with a hair
dryer. Keynoter Bernd Steinmuller of Germany will detail how Europeans are saving energy
through housing construction and why these techniques are appropriate for the Midwest.

Wind Energy Projects: Stalled but still Viable
by Drs. Robert and Sonia Vogl
Wind
energy projects in the Midwest have been flying the past few years thanks to federal
incentives which make it possible to recapture the costs of a wind farm within six years
and profit well into the future. Technological progress improved the performance and
efficiency of wind generators. High prices for oil and natural gas along with tax payments
to stressed county governments and revenues for landowners added to the appeal of wind
farms. As a clean energy source wind seems an ideal technology to reduce our dependence on
fossil fuels and imported energy.
Illinois
has two operating wind farms: one in Lee County and another in Bureau County with a third
under construction in Lee County. However, the Boone County Heritage Wind Farm was just
delayed by another vote at the County Board level. The Ogle County wind farm has been
delayed due to a lawsuit.
Despite
the virtues of being a carbon free source of energy which strengthens our quest for energy
independence, resistance to wind farms is growing. Most projects are opposed in terms of
their potential adverse impacts on scenic views, land values, tourism, migratory birds,
bats, and annoyances such as flickering, interference with tv reception and noise.
The
fundamental issue is conflicting land and water resource use. While people want clean
energy sources and a halt to global warming, they also want the areas in which they live
and play to be relatively free of human intrusions. Since wind farms impact large tracts
of land and towers can stand nearly 500 feet tall including 300 foot long blades, their
presence dominates a landscape.
Resistance
to wind farms in the land-scarce UK is so strong that nearly 70 percent of its projects
have been rejected. In Denmark and Germany, however, wind installations have flourished.
Roughly 20 percent of their electricity comes from renewable energy sources.
In
the United States wind generator capacity reached 9000 MW by 2006 and was expected to grow
by 40 percent this year with another 3400 MW slated for installation. However a long list
of challenges is likely to delay some installations. In Nebraska the impact on prairie
chickens is an issue. In Wisconsin the impact on sandhill cranes and bats is a concern. In
the Texas Gulf the concern is impacts on migratory birds. Possible hazards to shipping and
ferry lanes have also been points of contention. Wind farm developers are eager to install
turbines in the Great Lakes; critics have already voiced their complaints.
The
latest front page challenge to wind farms is their potential interference with radar for
both military and civilian air travel. An amendment to federal legislation inserted by
Senator John Warner of Virginia requires the Department of Defense to study and report on
the effects of wind projects on military readiness. Projects in North and South Dakota, Illinois
and Wisconsin received letters from the Federal Aviation Administration informing them
projects must be halted while the Defense Department study is being conducted. So far the
projects are only being delayed until risks to military operations are assessed and
resolved.
In
Illinois, a project in LaSalle County and another covering parts of Bureau and Lee County
are stalled. A letter objecting to the delays has been signed by six Midwest senators,
including Durbin and Obama, and sent to the Department of Defense and the Federal Aviation
Administration.
Wind
energy has always been an integral part of the renewable energy movement. Wind advocates
in South Dakota fear their immense resource will remain underutilized because it is costly
to ship the power to growing urban centers of demand. With contentious siting battles
underway in more populated areas, this distant resource may become viewed more favorably
than it now is.
Wind
energy will be an integral part of this years energy fair. The wind farm project
under development in Lee County will be presented by Bruce and Joyce Papiech.
Another
approach to capturing wind energy involves small home or farm installations which should
involve less controversy. Dave Merrill will cover the basics of homeowner installed
systems.
A
third approach to capturing wind energy involves placing smaller wind generators on
existing structures in urban and rural settings, avoiding additional intrusions on the
landscape. Bil Becker will report on his progress in placing wind generators on building
roofs in Chicago.
Jim
Starry will discuss his concept of placing smaller wind generators on existing power poles
wherever they occur. This approach can compensate for energy losses inherent in shipping
electricity long distances. Similar generators are already being used in some western
locations. Starry feels his design is unique and would be another effective way to make
use of clean wind energy.

Solar
Hot Water Heats Buildings at Rockford
Airport
by Drs. Robert and Sonia Vogl
Any
major change in the worlds energy consumption must start with how we, the
worlds largest energy user, produce and use energy. Leading energy experts calculate
that we have about a decade to make a serious dent in our fossil fuel consumption to avoid
the worst impacts of global climate change and dwindling supplies of low cost energy.
According
to a study by Lenius, Klein and Beckman at the Solar Energy Laboratory at the University
of Wisconsin-Madison three quarters of U.S. residential and commercial buildings could
meet half of their hot water and space heating needs with solar energy. With installation
done on only 7.5 percent of suitable buildings per year, the program would be completed in
a decade.
Such
a program would lessen vulnerability to volatile energy prices and our pollution load on
the environment, cut our risk of energy shortages and provide many jobs installing
systems. The U.S. Department of Energy estimates that water heating alone accounts for 15
percent of a households energy use.
A
solar hot water system can pay for itself within four to 10 years. Annual fuel costs
savings average around 70 percent. A good quality system can provide over 20 years of
maintenance free service. It can also be connected to an existing hot air system or
radiant heating system to provide supplementary heat to a room or an entire house.
All
solar water heating systems rely on the suns energy to heat air or a liquid which
circulates through a solar collector.
The
most common types of solar heating and hot water applications are for homes, multifamily
buildings, commercial buildings, and swimming pools.
A
new solar hot water space heating system has just been built at the Rockford Airport.
Little did we realize when we discussed this project with Bob Moreland prior to its
development the eventual magnitude of it.
Moreland,
a recently retired American Airlines pilot, noted that there were no available airplane
hangars at Rockford Airport, so he decided to build some. Theyre top quality big
commercial buildings, 16,500 square feet for the first building with 10 1500 twin engine
aircraft size units and 13,750 square feet for the second building which will contain 12
units for single engine aircraft. The first building also has a modern, well equipped
pilots lounge. Each pilot has his own condominium-like space for himself and his
plane. One building is up and operating. The second one is being worked on now.
The
buildings are extremely efficient. Theyre super insulated, with R-38 in the walls
and R-50 in the ceilings. Lighting is also very efficient.
But
the most important feature for Moreland was the heating system. A pilot can gain
immeasurable utility from a plane if its kept warm in winter. Using gas to
heat one of the huge buildings costs a fortune, but the sun provides free
energy. Moreland decided to use that free energy and hired Solar Service of Niles to
install a solar hot water system. A 400 square foot flat plate collector on the on the
south facing roof heats water which is then piped under the floors, providing radiant
heating. Rundle-Spence supplied much of the radiant heating design and materials and
worked with McClellan and Blakemore Architects of Rockford and Moreland to put the
innovative design together. Moreland and his tenants are pleased with the system which
makes winter heating drop from very expensive to not very expensive at all.
Its fun to watch it work. His son, also a pilot just home from Iraq, is
helping him with construction. Even though construction will not be complete until later
this summer, more than half the units have been sold or have deposits on them.
Bob
OBrien, airport manager, wants to bring general aviation back to Rockford. He has
been very supportive of the project, offering an attractive 60 year land lease.
Solar
Service will again be exhibiting at the Fifth Annual Illinois Renewable Energy and
Sustainable Living Fair August 12 and 13, 2006. Brandon Leavitt, owner, will again be
making a presentation. Last year, his practical workshop had an overflow crowd. Backward
to the Future, installer of evacuated tube hot water systems, will also exhibit and make a
presentation. Evacuated tubes operate at higher temperatures than flat plates.

The
Breath of the Planet - Are We Destroying our Oxygen Supply?
by Drs. Robert and Sonia Vogl
Carbon
buried under the crust of the earth allows us to breathe free oxygen. As we burn
increasing amounts of fossil fuels we combine carbon with that free oxygen releasing CO2
into the atmosphere. Our use of fuels is gradually reducing our oxygen supplies.
Little
attention has been given to atmospheric oxygen levels as climate change is a more
immediate threat. A slight drop in atmospheric oxygen over the past twenty years was
recently reported by the Commonwealth Scientific Research Organization in Australia.
Pristine air was measured at the remote Cape Grim Baseline Air Pollution Station. The
decrease found by this initial study is far less than typical fluctuations indoors or in
city air and will not interfere with human breathing.
We
all realize we can only survive a few minutes without oxygen. The presence of people
tethered to oxygen tanks has made us aware of the medical need for supplemental oxygen.
But most people seldom think about their own blood oxygen levels. Airline pilots are
tested to ensure their blood oxygen levels are high enough so they remain alert in flight.
Vehicle drivers are not tested even though low oxygen levels can contribute to their
falling asleep at the wheel. Victims of sleep apnea often have low blood oxygen levels
which increases the likelihood of inattentive driving.
Intersections
with high traffic levels and cars idling in traffic are the most common sites of reduced
oxygen levels in urban areas. High carbon monoxide emissions from vehicles reduce oxygen
levels in the blood adversely affecting human performance.
All
combustion regardless of the fuel used consumes oxygen and releases heat and pollutants.
The miles we travel and the fuel efficiency of our vehicles determines how much our
transportation choices pollute the air and consume oxygen. We assume the pollutants simply
disappear but many of them circle the globe and return within a week.
With
China and India emulating our transportation choices, pollution levels will rise
dramatically. Air travel is our fastest growing mode of transportation. By 2050 it is
expected to increase 900 percent as will the multiple adverse environmental impacts of its
growth.
Anyone
who phones environmental designer Jim Starry hears his message that with each gallon of
gasoline burned in a car, 10,000 gallons of air pollution are released. His dramatic
numbers are an attempt to get others to think about the impact their lifestyles have on
the air we breathe.
One
of his most eye catching pollution solutions is the Starrport, a new airport design which
will decrease pollution from plane departures, arrivals and taxiing. He has other ideas
and inventions to limit sources of pollution in our communities. Like any inventor, he
thinks some of these ideas could be turned into commercial products and manufactured in
this area.
He
will be making a presentation at the Fifth Annual Illinois Renewable Energy and
Sustainable Living Fair to be held August 12 and 13, 2006 (Google Jim Starry). Other
workshops, displays and vehicles will highlight alternative ways to reduce our oil
addiction and lessen the adverse impacts of our transportation choices.

Grown Wind Power
by Drs. Robert and Sonia Vogl
Last
night at dusk (June 16, 2005) our newly installed one kilowatt Bergey wind generator sat
waiting for a seven mph wind to turn the rotor to generate electricity. A morning breeze
produced five amps of power. As wind speeds pick up more power is produced.
Installing
the system was like an old fashioned barn raising as ten people, including Frank Schier,
were involved in the process. Dave Merrill of Byron, who installs both wind and solar
electric systems, directed the project.
The
system is known as the BWCXL.1-24. The one kilowatt 24 volt current system is designed to
charge batteries and supply electric loads as D.C. power which must be converted to A.C.
to match the power provided by Commonwealth Edison.
The
electrical generating turbine weighs 75 pounds and has three fiberglass blades that sweep
an 8.2 diameter. It is mounted on a 64 foot collapsable tower. Steel cables attached
to the tower at twenty foot intervals connected to ground mounts hold the tower in place.
The
turbine is free to pivot around the top of the tower so the rotor will always face into
the wind. A tail boom and fin keep the unit facing the wind up to speeds of 28 mph. Above
that speed the rotor turns away from the wind to prevent it from turning too fast and
being damaged. Most of the production occurs at wind speeds between 12 and 20 miles per
hour.
The
electricity generated by the rotor is carried down the hollow center of the tube and
underground to a controller. The controller limits the amount of voltage sent to the
battery pack to prevent overcharging and damaging it. The D.C. electricity is sent to the
inverter which converts it to A.C. to match the power supplied by the grid. Excess
electricity is sent back to ComEd which buys it for roughly the same price as they charge
us. With our 3.2 kW solar system and our 1 kW wind system, we should be close to meeting
most of our electrical needs with renewable energy.
With
the new system we will be able to provide both solar electric and small wind system
workshops for citizens interested in sustainable, renewable energy. It is the new global
energy paradigm.

Think
Before You Switch
by Drs. Robert and Sonia Vogl
The
best energy investment we can make is energy conservation and efficiency. We could cut our
excessive consumption between 30 and 75 percent and still live comfortable lives. As
consumers our purchases decide our direction.
As
children when we whined about the inconvenience of walking to school in cold weather, our
parents topped our complaints with stories of the rigors of their youth. While it never
seemed relevant to us, they conveyed the message that we could deal with it by adopting a
can-do attitude and dressing appropriately for the weather - cold, wet or hot. As
teenagers we walked in -30o temperatures dressed in woolen clothing and awkward galoshes
never giving style a second thought.
We
adjusted then and we can adjust now. If peak oil is a reality in the near future, we will
learn to. While we may not like the changes, they will be less severe if we start making
them now.
Another
factor should also be a reason for adjusting. We are often reminded of the economic costs
of consuming fuel in a car, home or appliance, but we seldom make a connection between our
behavior and the environmental destruction it causes.
When
authors of books such as The Limits to Growth warn of environmental destruction caused by
too many people consuming too many resources on a finite planet, few of us take the
conclusions to heart and consciously alter our lifestyles. We live in the moment with few
cares for tomorrow or those who follow us.
We
can make simple, effective changes today. If every family only used compact fluorescent
bulbs, our electrical consumption would drop by five percent, our air would be cleaner,
less climate altering carbon dioxide would be released and we would maintain the same
level of lighting we now enjoy. Think of them as a holiday gift to the planet. This simple
act would have a far greater positive impact on the state than the goal of two percent of
electrical production from wind farms by 2006.
If
instead we buy energy consuming electronic gadgets environmental consequences will
intensify. Such devices consumed five percent of household electricity in 1980 and consume
20 percent today. Sales of these products, including big screen televisions, digital
cameras, laptops and portable music players continue to grow. Televisions and accessories
alone can account for 10 percent of a households electric bill. Huge plasma TVs use
twice the electricity of standard TVs. Some use as much electricity as a refrigerator.
Those who buy these gadgets are also buying more nuclear power plants, more coal fired
plants and more wind farms.
The
latest gadget and the switch which turns it on has a direct connection to fuel
consumption, climate change, environmental destruction and increased sources of power
generation. Powering an appliance anywhere has environmental consequences somewhere - in
our back yard or a distant place. Whether the Rocky Mountains or a seaside resort is your
favorite vacation retreat, how you and your neighbors use energy today could make your
favorite place of refuge far less inviting.

Lovins: Climate Change, Efficiency and Profits
by Drs. Robert and Sonia Vogl
In
her recent address, Hunter Lovins indicated that what was happening at the Renewable
Energy and Sustainable Living Fair was far more significant for national security than
taking shoes off at an airport. She reminded us of the boom and bust cycle of oil prices
and the potential of an oil glut bringing prices down once again. At the time of her
presentation demand for oil from China and India was driving prices higher. She felt that
our troops were in harms way in Iraq for oil and that we are without a sensible
national energy policy.
She
reminded participants that every ecosystem in the world is in decline and our ability to
survive as a species is at stake. We treat our ecosystems as though they have no value,
yet they provide $30 trillion annually in services. Global warming is real and contributes
to climate instability placing human welfare at risk.
The
recent hurricane, Katrina, which caused so much damage, illustrates her point.
The
general scientific consensus on climate change and hurricanes predicts an increase in
their intensity. Higher ocean surface temperatures and air temperatures are key factors
producing more powerful, destructive hurricanes. While political pressures to rebuild
areas will be intense, economy, environment and human welfare would be better served by
reducing vulnerable coastal developments.
In
response to climate change concerns an increasing number of firms are directing efforts at
reducing their carbon footprint, or the amount of carbon dioxide they release producing
goods and services. As scientists call for a global reduction of up to 80 percent in the
amount of carbon released by 2050, some firms are finding carbon reduction a profitable
venture. Lovins cited the financial gains that British Petroleum, DuPont and STM have
experienced while cutting carbon releases. Additional financial opportunities selling
green tags, trading carbon rights and sequestering carbon in farm fields were pointed out.
She
reminded participants of the economic successes in the 1970s and early 80s
when we cut energy consumption 15 percent in six years while growing the economy 15
percent. Since we waste up to $300 billion annually on fossil fuels, an amount equal to
the annual energy consumption of Japan, we are only scratching the surface of possible
savings. |
