Israeli fuel cell start-up EnStorage Ltd. has raised $15 million in a Series B financing round.

U.S. private equity fund Warburg Pincus led the round, and was joined by all of EnStorage’s current investors, including Greylock Partners, Canaan Partners, Siemens TTB, and Wellington Partners, according to a report in “Globes“.

EnStorage was founded in 2007 by VP R&D Dr. Arnon Blum, Chief Scientific Officer Prof. Emanuel Peled of Tel Aviv University, Chairman Nachman Shelef, and former CEO Eran Yarkoni.

Many moons — and political news cycles — ago, I was very critical of the Obama administration’s “Cash for Clunkers” program, as much on green (environmental) impact as on green (cash) grounds. Later, I briefly became a darling of the Republican right when I was similarly skeptical of the “Cash for Refrigerators” appliance rebate proposal (they subsequently boomeranged on me when I questioned the relevance of ClimateGate).

But this is not about me. It is about the future of the “Cash for Stuff” model. Even as odds of getting a comprehensive energy and environment bill wane in this congressional session, a “Cash for…” proposal worth supporting has emerged.

And to the delight of bloggers and wordsmiths everywhere, it is as alliterative as it is promising. I give you “Cash for Caulkers.” (more…)

The British 10:10 campaign has only been in action for two months and has already received the praises of Oscar winner and Nobel Peace Prize laureate Al Gore, who claimed the movement was so good it should have a presence in the United States.

350.org , 10:10 is now taking its message around the world. By going global 10:10 will extend its unique ethos – along with its simple, contagious idea of asking people to cut their emissions by 10 per cent starting in 2010 – to more than 30 countries including the USA, India, France, Germany, New Zealand and China.

The plan is to hold the biggest day of climate action ever seen on the 10^th day of the 10^th month, 2010 and although that is still six months away, more than 800 local groups across the globe have signed on. (more…)

(Reuters) – Sporting goods maker Puma will launch eco-friendly packaging for its sneakers next year to reduce its carbon footprint, beating governments to the punch as it kisses old-fashion shoe boxes good-bye.

Puma said it would roll out the new packaging in the second half of next year and that by putting its shoes in cardboard frames wrapped in reusable shoe bags, it would save 8,500 tonnes of paper — the weight of more than 1,400 adult elephants.

It also said the change would mean a reduction of 60 percent in water and energy used during the production process and the amount needed for transportation due to lighter packaging (more…)

With subsidy support for corn ethanol under attack, algae and cellulosic look to secure federal support.  The result: a subsidy battle in the Capital that could dictate the direction of the U.S. biofuel industry over the next decade.

Has the transition to advanced biofuels turned the corner?

Probably not yet, but sustainable alternatives are beginning to get their day in the sun in Washington D.C.  The result: a subsidy brawl is taking shape that will likely dictate the direction of U.S. biofuels development over the next 5-10 years.

There are a few moving elements, but here are the recent highlights: (more…)

This month marks the 40th anniversary of Earth Day, an event that has attracted millions to environmental causes. But winning passage of meaningful legislation on climate change requires more than slogans and green talk — it demands intense, determined political action.

Size doesn’t matter.

Or at least, size is not the only thing that matters. In 21st century American democracy, massive public support is certainly desirable, especially over the long run. But what really counts with Congress is intensity.

A huge majority of Americans favor gun control, for example. According to the National Opinion Research Center at the University of Chicago, four out of five believe a police permit should be required for the purchase of a firearm. (more…)

As John McDonald tells it, smart grid needs GOLD. And he’s not talking money. GOLD stands for Graduates of the Last Decade, the technology savvy, risk-taking engineers and technicians who may be among the greatest benefactors of the new smart grid movement. While most recent college graduates face dismal employment prospects, for the GOLD kids, the job market is, well, golden.

“I’ve never seen electric utilities and suppliers outbidding each other for a bachelor’s degree,” said McDonald, who has had 35 years in the energy business and now serves as an IEEE Fellow and general manager of marketing for GE Energy T&D.

Have we outsourced global warming? Critics of cap and trade systems or carbon offsetting have argued that buying a carbon credit is like a medieval indulgence. Rather than saving the planet, it allows me to buy a clean conscience. I’ll give two examples of how this might be true.

Lets say I want to have no carbon emissions. The average American produces 20 metric tons of carbon dioxide a year. Rather than reduce by 20 tons I just buy 20 credits.

Those 20 credits might represent 20 tons of carbon that have been sucked out of the air by fast growing trees. Or do they? What if those trees would have been planted anyway? Then I’m just spending some money to keep polluting — and the world keeps warming.

Top News: This week, President Obama startled both his allies and critics with a plan to permit drilling for oil off the Southern Atlantic states and in the Gulf of Mexico. Meanwhile the Secret Service, in a stroke of karmic justice, denied the president’s request for a hybrid limo.

On Saturday, Apple’s long-awaited iPad emerged to great fanfare, and with it some schwag and a initial smattering of green apps.

Wising Up to the Smart Grid: After years of talk and speculation, several big U.S. companies revealed that the smart grid lies at the center of their business plans. At the New York Auto Show, Ford and Microsoft announced energy-management software designed for the thousands of people who will plug in their electric cars or hybrids at home. Connecticut Light & Power applied for permission to scrap its flat-rate price structure in favor of one that penalizes customers for overloading the grid. Under the proposal, Connecticut electricity would be ten times cheaper at night than it would be in the middle of the day, when the A/C units are cranking.

On Tuesday, Agriculture Deputy Secretary Kathleen Merrigan and Assistant Secretary of the Navy for Energy, Installations and Environment Jackalyne Pfannenstiel kicked off the first of several energy forums in front of a packed room to look at ways to increase biofuels production and meet the Navy’s renewable energy needs.  The forum comes as a result of the Memorandum of Understanding (MOU) recently signed by the USDA and the Navy to encourage the development of advanced biofuels and other renewable energy systems.

As the President pointed out in his energy security remarks last week, “…the Pentagon isn’t seeking these alternative fuels just to protect our environment; they’re pursuing these homegrown energy sources to protect our national security.  Our military leaders recognize the security imperative of increasing the use of alternative fuels, decreasing energy use, reducing our reliance on imported oil, making ourselves more energy-efficient.”
