An activist caravan to bring one of Jimmy Carter’s solar panels back to the White House symbolizes not only the time the U.S. has lost in developing new energy technologies – but also the urgent need for taking action on climate.

As I write this piece, we’re in the midst of a (biodiesel) road trip to Washington, D.C., (more…)

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…)

If micro-inverters are the current craze in the solar industry, then I predict that solar energy monitoring systems will be the next big thing.

Micro-inverters (and other parallel technology) are given lots of attention because they can increase the efficiency of a system by up to as much as 10%-20%. Similarly, solar electricity systems that are hooked up to monitoring systems have a 10% energy production increase over systems that are not hooked up to monitoring systems, according to Will Shortt, CEO of Deck (more…)

Fannie Mae and Freddie Mac have already put a halt to many state clean energy and energy retrofit programs affectionately known as Property Assessed Clean Energy (PACE) or PACE like obligations. In July, California Attorney General and candidate for Governor, Jerry Brown, filed a lawsuit against Fannie Mae and Freddie Mac alleging that Fannie Mae and Freddie Mac (more…)

From a technological point of view, India is an excellent place for the development of solar energy. It gets plenty of sunshine for most parts of the year, with the summer temperatures well in excess of 100⁰ F in most parts of the country. To the northwest, India has the Thar Desert that has been identified as a feasible spot for the development of solar power, since the area is mostly an arid land and gets plenty of sunlight.

Apart from the solar power generation potential at a large scale, there is plenty of scope for household solar harvesting. (more…)

The biggest deterrent for retail consumers to install solar panels on their rooftops is the upfront cost, which may vary depending on the country and state incentives. The cost of repair is on the owner of the panels (most panels are insured for 20 years or more and since they have no moving parts are pretty stable). The inverter that coverts the current to a usable form needs to be (more…)

Big solar news from Illinois last week. The Wanxiang America Corporation held a ribbon cutting ceremony for a new $12.5 million, 40,000 sq ft solar module plant in the town of Rockford. It’s yet another example of how product follows policy and how manufacturing follows markets. It is yet another example of how strong solar programs beget new jobs. And of how the (more…)

Electric vehicles (EVs) are widely considered an inevitable part of the future of transportation. Every major auto manufacturer is working on their own electric model, with notables like the Nissan Leaf, Chevy Volt and an electric Ford Focus scheduled for release within the next year or two.

It seems that the most important meetings at SunPower all take place in the Tiffany & Co. conference room. In fact, all the other conference rooms are named after significant SunPower installations—Nellis (14.2 MW), Bavaria One (10 MW), Moscone (675 kW), and Olivenza (18 MW).

Perhaps the high-quality, luxury jeweler, (more…)

Farmers and solar energy businesses are relieved after the Ontario Power Authority (OPA) announced on August 13 that recent changes to the pricing scheme for small-scale, ground-mounted solar panel installations under Ontario’s micro feed-in tariff (microFIT) will not be applied retroactively.
