Winning the battle of energy savings
Two years ago, the New Jersey Army National Guard asked the Army Corps if it could construct a solar power project so they could save energy and money as they had done for them on previous solar power projects.
Addressing the challenge of expiring federal incentives for renewables
With the elimination of federal incentives for renewable generation, more than $20 billion may be shifted from the federal level (i.e. all taxpayers) to the customers in states with RPS targets.

Cogenra Solar and Kendall-Jackson Winery Unveil Nation's Largest Rooftop Solar Cogeneration Array
Cogenra Solar, a provider of distributed solar cogeneration systems, today announced the nation's largest rooftop solar cogeneration system to date at Kendall-Jackson's Kittyhawk winery in Windsor, California. Expanding on Kendall-Jackson's existing energy and water conservation projects, the 96-module, 241kW hybrid solar photovoltaic (PV) and thermal array is expected to save approximately $30,000 in annual energy costs.
"Our founder Jess Jackson was a trailblazer who made sustainability a core part of Kendall- Jackson's DNA largely through innovation"
U.S. Congressman Mike Thompson and local business leaders convened today at Kendall-Jackson's Wine Center to celebrate the company's commitment to sustainability and unveil the solar cogeneration system, now supplying solar hot water and electricity to power the winery's extensive tank and bottle washing operations.

The long, long (long) road for algae fuel
Earlier this week algae fuel startup Sapphire Energy announced that it’s in the process of raising a whopping $144 million from private investors, which will be used to build out its first commercial demonstration algae farm in New Mexico. That farm could be able to produce 1.5 million gallons of Sapphire’s green crude per year by 2014, says Sapphire’s VP of Corporate Affairs, Tim Zenk.
That might sound impressive, but it’s a far cry from the company’s previous projections. Back in 2009, Sapphire was hoping its algae farm would be able to produce 1 million gallons of green crude per year by 2011, followed by 100 million gallons per year by 2018, and 1 billion gallons per year by 2025. When Sapphire made those projections, the sheer volume was so much more than any of their competitors were putting out there, that I asked if Sapphire was going to be “the gorilla of algae fuel?“

RENEWABLE ENERGY EXPERIENCES EXPLOSIVE GROWTH DURING FIRST THREE YEARS OF OBAMA ADMINISTRATION
According to the most recent issue of the "Monthly Energy Review" by the U.S. Energy Information Administration (EIA), with data through December 31, 2011, renewable energy sources expanded rapidly during the first three years of the Obama Administration while substantially outpacing the growth rates of fossil fuels and nuclear power.
Between January 1, 2009 and December 31, 2011, renewable energy sources (i.e., biofuels, biomass, geothermal, solar, water, wind) grew by 27.12%. By comparison, during the same three-year period, total domestic energy production increased by just 6.72% with natural gas and crude oil production growing by 13.66% and 14.27% respectively. Moreover, during the same period, nuclear power declined by 1.99% and coal dropped by 7.16%.

Floating Windmills in Japan Help Wind Down Nuclear Power: Energy
Japan is preparing to bolt turbines onto barges and build the world’s largest commercial power plant using floating windmills, tackling the engineering challenges of an unproven technology to cut its reliance on atomic energy.
Marubeni Corp. (8002), Mitsubishi Heavy Industries Ltd. (7011) and Nippon Steel Corp. (5401) are among developers erecting a 16-megawatt pilot plant off the coast of Fukushima, site of the nuclear accident that pushed the government to pursue cleaner energy. The project may be expanded to 1,000 megawatts, the trade ministry said, bigger than any wind farm fixed to the seabed or on land.
“Japan is surrounded by deep oceans, and this poses challenges to offshore wind turbines that are attached to the bottom of the sea,” Senior Vice Environment Minister Katsuhiko Yokomitsu said at a meeting in Tokyo this month. “We are eager for floating offshore wind to become a viable technology.”
