The Washington Post brings to light just how big an impact Obama’s pledge will have for renewable energy companies. We’re already seeing high profile interest in funding entrepreneurs in solar, wind and alternative energy; early next year we could see a boom!
President-elect Barack Obama wants the nation to derive 10 percent of its electricity from renewable energy sources by 2012, up from 2 percent today. That comes on top of the global push for green power, making wind and solar power companies a good bet.
It’s been a rocky road for the high flying sector, recently as the credit crunch has reduced investors willingness to capitalize any company, least of all those involved in risky new ventures. But, that hasn’t stopped big names like T. Boone Pickens from investing in wind power and..

By turning a long line of mirrors, the first solar thermal plant in nearly two decades was launched last week in Bakersfield, California. Unlike solar photovoltaic systems that convert sunlight into electricity, this plant will focus sunlight on tubes that contains water. The light heats the water, creating steam, thus turning turbines.

A newly discovered material called ‘black silicon’ is between 100 and 500 times more sensitive to light than conventional silicon, and could be used to revolutionize solar energy generation.
The material was discovered when a team of Harvard University scientists shone an ultra-powerful laser (briefly producing the same amount of energy as the sun falling on the entire surface of the Earth) on a silicon wafer, before adding sulphur hexafluoride. The result was a silicon wafer that looked black to the naked eye, but when examined under an electron microscope turned out to be covered with a massive amount of ultra-tiny spikes.

An Australian scientist has developed a new method of manufacturing solar cells using nothing more than some nail polish remover, a pizza oven and a standard inkjet printer.
The iJET technique is so easy and cheap to carry out that it could revolutionize access to solar technology in the developing world.
In a recent radio interview (audio), Nicole Kuepper, a 23 year-old PhD student at the University of New South Wales, explained the process.

Morgan Solar, a Toronto-based company launched last summer, believes it has the answer to creating simple and cheap solar concentrators.
While other companies are working to make solar cheaper by using mirrors or lenses to magnify sunlight that is directed into solar cells, Morgan Solar takes a different approach. Their system uses a thin sheet of acrylic to concentrate sunlight 750 times. The sunlight is directed to a tiny cell on the edge of the plastic, greatly reducing the amount of material needed.
Orlando, Florida, recently became one of 12 cities across the U.S. chosen as a federal Department of Energy (DOE) “Solar America City.”
Each of the dozen cities will receive $200,000 to advance the use of solar technologies in their communities. All the cities were selected for “their commitment and comprehensive approach to the deployment of solar technologies and the development of sustainable solar infrastructures,” according to the DOE.
New solar technology based on organic photoelectrochemical, dye-sensitized cells, is being implemented in hundreds of every day use consumer products ranging from clothing, smart cards, gadgets, lighting to windows and building facades.
Konarka, a Lowell, MS, company pioneering the technology, says it’s ready to market the products in which the solar dye has been implemented after the summer. The technology has a light to energy conversion rate of of 7.2 percent. This compares to 16 to 20 percent of regular, photovoltaic, solar technology.
The advantages of dye solar technology include flexible implementation options. Dye-based solar technology also converts low light and light rays at obscure angles. Plus the electricity generated can be applied to specific current wavelengths.
