Fighting a war on the ground in Afghanistan has to be one of the hardest things a young person can do.
Fortunately, the U.S. Department of Defense, or DOD, is on the ground with our troops offering help and support – albeit in some very unexpected ways.
According to Tony Bui, an engineer with (more…)

AT&T is bulking up its latest corporate sustainability plan.
A 296-kilowatt solar power system has officially been activated in San Diego, and it’s just the first of six company sites around California scheduled for solar installation. The goal is 2 megawatts of clean solar electricity. The Trade Street site in San (more…)

The use of renewable sources of energy in Europe continues to grow at a brisk pace and energy efficiency also is improving, significantly reducing reliance on coal and natural gas, according to a new report. In
2009, renewable energy accounted for 18.4 percent of the European Union’s primary energy production, an increase of 8.3 percent from 2008, according to a (more…)

The government of St. Lucia has signed an agreement with a U.S.-based company to develop a series of geothermal plants they say will produce more than 120 megawatts of electricity, with plans to export much of that energy capacity within five years. The Caribbean island nation, located on the volcanic arc of the Small Antilles and home to about 175,000 people, has granted (more…)

British designers are developing a new type of offshore wind turbine that rotates on its axis, mimicking the spiral of a sycamore seed, and that stretches nearly 900 feet (275 meters) from tip to tip.
The so-called Aerogenerator has two enormous arms that extend from the base of the structure in a V-formation, each (more…)

Whenever you suggest that renewables could one day supply a large proportion of our electricity, scores of people jump up to denounce it as a pipedream, a fantasy, a dangerous delusion. They insist that the energy resources don’t exist; that the technologies are inefficient; that they can’t be accommodated on the grid; that the variability of supply will cause constant blackouts.
I suspect that no amount of evidence will sway some of these people. There’s a large contingent which seems to hate renewables come what may. (more…)

The widespread adoption of energy efficient light bulbs, fans, refrigerators, air conditioners, and irrigation pumps can overcome India’s electricity shortage by 2013 and significantly reduce the country’s rapidly growing carbon dioxide emissions, according to a new report. The study by the Lawrence Berkeley National Laboratory said such simple energy efficiency measures could add $608 billion to India’s gross domestic product by 2020 because they would eliminate the chronic energy shortages that frequently force businesses and factories to reduce production.

Imagine a world where you can buy electricity from your choice of vendor (not the utility) at prices that can be negotiated with the vendor. Kind of like shopping at eBay or Amazon. Want to buy a week’s worth (1,000 kWh) of power from SebaSolar at 9 ¢/kWh? Just click here. How about switching to WindyWelly for the weekend (300 kWh) at 8.5 ¢/kWh? Click! Wait, NeoGeo just announced it has a ‘fire sale’ at 7 ¢/kWh for next Tuesday through Thursday. Click!
Well, imagine no more. This electricity world exists today. To see this new architecture of energy at work I went to Wellington, New Zealand.
Powershop is a unit of Meridian Energy, the largest electricity generator and retailer in New Zealand. “The vision of Powershop is to be like eBay for electricity,” says CEO Ari Sargent. “Any electricity generator in New Zealand, including Meridian’s competitors, can offer their own brands of electricity at different prices and different times.”

The Oil Spill’s Unlikely Victim: As oil from the Deepwater Horizon spill continued to gush into the Gulf of Mexico, it tarred the feathers of an endangered creature: the climate bill. Sens. John Kerry and Joe Lieberman introduced a retooled American Power Act on Wednesday to little fanfare. Perhaps that’s because the media’s klieg lights were already divided between the grilling of oil executives on Capitol Hill or the so-far hapless efforts to plug the leak. Or maybe it’s because the two senators took to the dais without their erstwhile Republican ally, Lindsey Graham. Nevertheless, it was ironic to see a solution to our fossil-fuel addiction pushed to the side because of a fossil-fuel disaster. Must we cap the gusher before we get a cap on CO2?
More Electric Cars Roll to the Starting Line: You’ve heard that the Nissan Leaf and the Chevy Volt are on the way, but how about the Think and the Wheego? Wheego, a maker of electric putt-putt vehicles based in Atlanta, hopes that 200 highway-ready copies of its Whip Life will roll off the assembly line by August, months ahead of the well-publicized launch of the Leaf. Meanwhile, the Norwegian carmaker Think raised $40 million this week and plans to start assembly of the tiny Think City in Elkhart, Indiana in early 2011.

Emefcy, a microbial fuel cell startup based in Caesarea, Israel, has raised $5 million at a company value of more than $10 million, post-money.
UK investment fund Pond Venture Partners led the round, joined by current Emefcy investors Israel Cleantech Ventures Funds and Plan B Ventures, according to Globes and IVC Online.
Emefcy, co-founded by serial entrepreneurs Eytan Levy and Ronen Shechter, is developing the MEGAWATTER™ technology. This technology produces low cost electricity (at $0.10/kWhr) and hydrogen in a bio-electro-chemical process from wastewater treatment by leveraging Microbial Fuel Cell (MFC) technology.
