Military ‘Battle Lab’ Cashes In On Solar Savings -- Earth Techling

No one ever said training for battle was easy, nor energy-efficient. The “Battle Lab” is a U.S. military facility in New Jersey where more than 20,000 soldiers prepare and train for battle. The lab includes shooting ranges, vehicle rollover trainers and other high-tech simulators. But those high-tech tools suck up millions of kilowatts of power.

Now, more than a quarter of the training facility’s power is being provided by renewable energy sources. The Army Corps of Engineers along with the help of contractor P & S Construction helped complete a solar power project onsite at Joint Base McGuire-Dix-Lakehurst. Photovoltaic solar panels were mounted to the roof of the Battle Lab, covering approximately 71,000 square feet.

A Youngster's Bright Idea Is Something New Under The Sun -- Wall Street Journal

Aidan Dwyer Took a Leaf from the Trees and Electrified International Debate

NORTHPORT, N.Y.—A new way of collecting solar energy has polarized scientists around the world and ignited fierce debate on the Internet, where the innovator in question has been called everything from an alien to the agent of a global conspiracy.

Maybe a better title would be an intellectual Hannah Montana. That's because the scientist, Aidan Dwyer, is 13 years old.

This past summer, Aidan won a national science competition with what seemed to be a bright idea: His research appeared to show that solar panels arrayed like the leaves on a tree collect sunlight more efficiently than traditional setups.

Surfing A Wave Of Californian Sunshine As America Looks For Renewable Future

The eSolar plant in the Mojave Desert generates enough electricity to power 4,000 homes

From Times Online:

On a dry, scrubby plain on the edge of the Mojave Desert north of Los Angeles, 24,000 mirrors track the Sun’s progress across a clear, blue sky. The neat ranks of heliostats and the computer algorithm that moves them make the Sierra SunTower plant a focal point for a novel type of power generation and a new wave of energy companies looking to turn the search for renewables into successful businesses.

Solar tower technology uses mirrors to reflect sunlight on to a thermal receiver atop a tower. The reflected sunlight boils water inside the receiver to create superheated steam at 440C (824F), which drives a turbine and generates electricity.

From The Christian Science Monitor:

Discount deals and tax incentives help homeowners go solar.

If faced with a $700-a-month electric bill, one might be inclined to cast one’s eyes heavenward. So it wasn’t surprising that Lisa Max took a good hard look at rooftop solar panels as a possible solution to her soaring energy costs. But the estimates “shocked” the San Rafael, Calif., homeowner.

It’s a typical scenario faced by US homeowners who are eyeing solar energy as a way to help the environment and save themselves some cash at the same time. When they crunch the numbers, the financial clouds descend.

Can Saharan Solar Power Save Europe?

Is it a mirage? Some experts think so, others say it will become a reality. AP

From Spiegel Online:

Some say it's a foolish fantasy, others believe it has the potential to save the world from the effects of climate change. The German-led Desertec initiative to build a massive solar thermal power plant in the Sahara Desert has both advocates and critics. SPIEGEL ONLINE looks at the current state of play.

For years, the idea of generating solar power for Europe in the Sahara was dismissed as pure fantasy. But then all of sudden it was happening, and Desertec was making headlines worldwide.

Solar Panel Costs 'Set To Fall'

The fall in cost is due to the increased lifetime, the institute says

From the BBC:

The cost of installing and owning solar panels will fall even faster than expected according to new research.

Tests show that 90% of existing solar panels last for 30 years, instead of the predicted 20 years.

According to the independent EU Energy Institute, this brings down the lifetime cost.

The institute says the panels are such a good long-term investment that banks should offer mortgages on them like they do on homes.

Solar Power Costs 50% Lower Than Last Year

From Scientific American:

New research by leading alternative energy research firm New Energy Finance finds that solar power will cost less by about 50% at the end of 2009 compared to the end of 2008.

The costs are pre-subsidy, so they could be much lower if you take better government subsidies into account.

But it isn’t only solar that’s down in cost. It’s other renewable energy sources, too.
The research company found that equipment costs (in solar, wind, and other sectors) decreased throughout the year but these were offset by increasing financing costs. However, equipment prices are expected to continue falling whereas the financing market is expected to get better.

Solar Superpower: Should Europe Run On Sahara Sun?

More energy than we could ever possibly need, but how can we tap into it?
(Image: Chris Anderson/Aurora/Plainpicture)

From New Scientist:

EVERY two weeks, the sun pours more energy onto the surface of our planet than we use from all sources in an entire year. It is an inexhaustible powerhouse that has remained largely untapped for human energy needs. That may soon change in a big way. If a consortium of German companies has its way, construction of the biggest solar project ever devised could soon begin in the Sahara desert. When completed, it would harvest energy from the sun shining over Africa and transform it into clean, green electricity for delivery to European homes and businesses.

Solar Snafu: The Contractor Finally Installs The Panels, But Goofs

From Scientific American:

Editor's Note: Scientific American's George Musser will be chronicling his experiences installing solar panels in Solar at Home (formerly 60-Second Solar). Read his introduction here and see all posts here.

The first message I got from my wife last week was happy news indeed: “Solar guys are working on our roof!” As readers of this blog know, we’d started the process of installing solar panels back in February, and we had no idea what were getting ourselves into. The red tape for the state and utility subsidies took through the end of May. Then we had to get our roof restored, which added a couple of months. In early July, I told myself, the wait was over. How wrong I was.

Introducing The Most Efficient Solar Power In The World

Image: Randy Montoya

From Discovery Magazine:

It's taken 25 years, but a new solar-thermal plant in New Mexico has finally broken the old efficiency record.

In 1986 solar panels were literally ripped from the White House roof. But political will and financial incentives have reignited the search for efficient, affordable ways to harness the sun’s energy. Two new solar thermal technologies—which focus sunlight to create heat rather than convert it directly to electricity, as photovoltaics do—promise to make solar power practical at vastly different scales.

Solar Power Outshining Colorado's Gas Industry

From Time Magazine:

(DURANGO, Colo.) — The sun had just crested the distant ridge of the Rocky Mountains, but already it was producing enough power for the electric meter on the side of the Smiley Building to spin backward.

For the Shaw brothers, who converted the downtown arts building and community center into a miniature solar power plant two years ago, each reverse rotation subtracts from their monthly electric bill. It also means the building at that moment is producing more electricity from the sun than it needs.

"Backward is good," said John Shaw, who now runs Shaw Solar and Energy Conservation, a local solar installation company.

Good for whom?
