Greenpeace USA rolled through my town, Bloomington, Indiana this weekend as part of its national tour to showcase solar energy. Rolling Sunlight will visit 50 communities across the nation talking to people and filming their own comments on how global warming is affecting their lives or will affect their children’s lives.

Their schedule for the next few weeks follows; the tour will proceed through October 16th where it will end in Washington, DC.

9/2 Columbus, OH
9/5 Phoenixville, PA
9/7 Philadelphia, PA
9/10 Elmira, NY
9/12 Oneonta, NY

The presence at these events consists of a 26-ft. biodiesel-fueled truck, a video camera, and an “action tent”, plus 256 square feet of solar panelsupplying enough energy to power three homes. At the action tent visitors can learn more about global warming by viewing videos and write a postcard to their local representatives to pressure them to act on climate change legislation.

Thin film solar technology has attracted interest from venture capitalists because of its higher efficiency, lower use of limited silicon, and more easily automated production processes. Now, established Japanese players in the solar arena are getting in the thin film game, followed by companies in China and India, as reported in Renewable Energy World.

Solar air conditioning has so far been the holy grail of the solar energy world, but now SolCool seems ready to make the dream a reality. With air conditioning being the heaviest user of electricity in many parts of the world, the 600-watt maximum average usage level of SolCool units will significantly alleviate strains on the electric grid. And, SolCool units can run on wind, solar, generator, electric [...]

Data centers, the nerve centers for the computing world, use an estimated 2% of all energy used in the United States, and are also heavy users of water. At an AeA presentation I attended in May of this year, Microsoft’s Lewis Curtis shared the following:

In 2006, U.S. data centers consumed 61 billion kilowatt-hours of electricity, enough to power 5.8 million U.S. households, costing companies $4.5 billion
If this trend [...]

Big money is backing wind power, and the number of investors ready to step up to the plate continues to grow. But according to an article in Renewable Energy World, that growth is hampered by a lack of a nationwide “electronic transmission superhighway”.

In the sixties America created the interstate superhighways that now crisscross our nation. Now, our country’s energy security depends on a new interstate initiative. Will the U.S. government step up to the plate?

“Across the country, hundreds of wind projects comprising tens of thousands of wind turbines are on hold because no one wants to step forward and pay for upgrades that will primarily benefit others. The obvious solution to this problem is a policy framework that will allow firms interested in building new transmission to collect the costs of the infrastructure investment from those who will benefit from it.”

Richard Sergel, president and CEO of the North American Electric Reliability Corporation (NERC), and Kevin Kolevar, DOE’s assistant secretary for electricity delivery and energy reliability, have pointed out in recent testimony before Congress that all low-carbon technologies, from large-scale wind projects to concentrated solar power, and even nuclear and “clean coal” technologies, require an updated electric grid because they are most often located in remote areas. The map above shows the Transmission Superhighway Vision put forth by the American Wind Energy Association and American Electric Power, an investor-owned utility that spans 11 states.

As tech giants rush into the solar cell business, their competition promises to bring down the cost of solar photovoltaic (PV) panels used to generate electricity. PV modules use silicon cells, which are also used in computer chips. But with the traditional chip business growing at only 5% annually, tech companies are looking for a new market niche to grow.

This is good news for the solar industry, where cost [...]

Armed with a survey that found that 63% of college applicants would use a college’s environmental commitment as a reason to choose to go to school there, the Princeton Review has added a “green rating” to its college rating system. EcoAmerica partnered with the Princeton Review on the study of students’ attitudes about the environment.

The Association for the Advancement of Sustainability in Higher Education, a member [...]

EDN reports that chip companies are gearing up to supply the widespread deployment of Smart Meters. Smart Meters provide real-time information on energy use so that homeowners can immediately see the effect of appliances, light bulbs, and computers on their energy usage and, their bills. Itron, Zigbee Alliance, Ember Corporation, and Teridian are some of the players in the smart metering arena that expect [...]

As ethanol from corn comes under fire due to rising corn prices, attention is turning to other ethanol sources. Plans are in the works to build a plant in northwest Indiana which would make ethanol from municipal waste. Approval of the plant was announced by the Lake County Solid Waste Management Board in January 2007.

And Chicago’s WBEZ reported this week that Indiana Ethanol Power is now [...]

Samsø, a Danish island in the North Sea, has become entirely energy self-sufficient, by using wind energy, solar and other renewables. The community was puzzled when it was announced in 1997 that it had won a government prize awarded to a community who would create a renewable energy plan; an engineer had submitted the entry without telling anyone but Samsø’s mayor. Interest was high after the award, but then fell off. It was Soren Hermansen, a lifelong resident of the island, who took on the task of turning the plan into action. The story of how he did it is a blueprint for other communities around the world.

In the nineties, the island of 4,300 people imported all their energy, mostly in oil tankers, and paid little attention to where it came from. In a fascinating article in The New Yorker magazine, Elizabeth Kolbert reports that:

“Then, quite deliberately, the residents of the island set about changing this. They formed energy coöperatives and organized seminars on wind power. They removed their furnaces and replaced them with heat pumps. By 2001, fossil-fuel use on Samsø had been cut in half. By 2003, instead of importing electricity, the island was exporting it, and by 2005 it was producing from renewable sources more energy than it was using.”
