Gay and Art
Nelson
Gay and Art Nelson of West Tisbury have had hopes of becoming energy
independent ever since the oil embargo in the 1970s, which left the
Island vulnerable to a shortage in fuel. At that time, there were
tax credit and rebate incentives across the country to support local
renewable energy. According to Art, they had the potential to prevent
what he and others believe is an impending energy situation.
Solar-powered homes got a false start back then, as did wind
power, says Art. But the new technology makes it so easy,
the Island is back on track.
Years ago the Nelsons were happy to generate enough solar power at
their wilderness camp to run a refrigerator and lights. Now the solar
panels on their home in West Tisbury regularly generate a surplus
of energy that they sell back to NStar.
It feels good to be feeding the grid, says Art. On
a sunny day, its comforting to watch the electric meter spin
backward. Since last August when we installed the new panels, we have
generated over three thousand kilowatt-hours. If our roof were facing
directly south and had a higher pitch, we could make even more.
Like many islands, Marthas Vineyard has a colorful energy history
that goes back for centuries and includes windmills, whale blubber,
fuel tankers, contemporary submarine cables, and now photovoltaic
cells in solar panels.
I think some people assume that solar isnt a good source
for us here because we dont have enough direct sunlight, but
that is not the case, says Gay. There are places in northern
Europe and even higher latitudes that are far more rainy and cloudy,
yet theyve been relying on solar panels for decades. The biggest
shortage here is economic incentive.
Watching the electric meter run backward has become a favorite pastime
of her grandchildren. But, according to Gay, when there are a lot
of kids in the house running around, taking showers and powering up
electronics, they tend to use up everything the panels generate. Running
the laundry and other machinery on sunny days makes a big difference.
Glenn and Linda Hearn
In college in the 1960s, Glenn Hearn used a solar panel with a couple
of wires and a plug to power his transistor radio. Since then he has
been interested in the science of renewable energy. When Glenn designed
and built his own house in West Tisbury 10 years ago, he faced the
roof precisely south and planned ahead for solar panels, knowing that
the technology was evolving and would someday be up to speed. The
most difficult thing, he remembers, was predicting when panel manufacturers
would get production up and the price down enough to make it cost
effective for heating and powering homes.
In the 60s and 70s, people got tax credits for doing the right
thing, says Glenn. The credits motivated everybody to
insulate buildings and to think about renewable energy. At the time,
it made a huge difference. Our government missed the boat when it
took away incentives, so now we have a very complicated economy around
energy that we must live with. The future will be interesting. I hope
that someday well have fuel cell designs so sophisticated that
our cars will power our homes.
For now, Linda and Glenn are content with the three arrays of six
panels each that they have on the roof. The system is estimated to
produce about 2,700 kilowatt-hours a year. Between March 2004 and
October 2004 they generated between 200 and 400 kilowatt- hours per
month. In January, with the sun lower in the sky, more cloud cover,
and snow drifting over the panels, production fell to 85 kilowatt-
hours, enough to run some appliances.
With or without photovoltaic cells, Glenn originally designed the
home to take full advantage of the suns energy, orienting the
windows to optimize sunshine in the winter and shade in the summer.
Though Linda wasnt directly involved with the building process,
the topic of solar research and development has peaked her interest
since the 1970s, when there was plenty of optimism for renewable,
locally generated energy.
I prefer the solar to fossil fuel, because I always know where
my homes energy is coming from, says Linda. Its
comforting.
Susan and Bob Wasserman
Though it is easier to plan for solar in new construction than to
retrofit a house later, Bob and Susan Wasserman love Victorian homes.
When they made the decision to go solar with their West Tisbury home,
built in 1863, they contacted local architect and solar specialist
Kate Warner.
This launched a project that is now complete.
Its been rewarding, says Susan. The project
appealed to a sense of responsibility that I grew up with. We remember
the Great Depression. I never assume that resources are unlimited
and Im not comfortable with wasting anything.
The first thing they did was to get a free home energy audit, sponsored
by Cape Light Compact, available to every Island resident (contact
800-797-6699). After the audit, the Wassermans got a detailed report
on where they were losing heat and exactly what was using energy where,
and to what extent. Through efficiency and proper insulation, the
home reached its energy conservation goal. Susan was surprised by
how easy it was to cut down on kilowatt hours. The great thing
is that there is no deprivation when you maximize your energy efficiency.
Most things were a matter of being more aware.
A solar array was installed next to their vegetable garden. It now
generates about one third of their households energy, including
a home office of fax machines, phones, copiers, and other equipment.
On a particularly sunny day the array can produce much more energy
than the Wassermans need. In that case, their electric meter spins
backward, and NStar purchases the renewable energy.
Bob Wasserman says he is not doing this for the payback, although
it will eventually pay for itself. My payback is how pleased
I am, he says. Fossil fuel depends on sources of supply
over which we have little or no control. Its not about what
politician you support, because the system itself is political, and
there is no way around it but to think independently as an Island
community.
Susan agrees, We have terrific, smart people on the Vineyard,
and I think well get it right by learning from other islands
around the world and by communicating well. Together we can create
a role model for others and a healthy place to live. Feeling good
about our energy is an intriguing idea.
On Saturday, July 16, there is a Solar Home Tour in West Tisbury from
9 am to noon, all within walking distance of the Farmers Market.
A good place to start is at 1085 State Road. Look for signs and yellow
balloons or see the Calendar section of The Times for site locations.
