Barack Obama showed his confidence in the solar energy and the jobs that the renewable energy sector can create by visiting the solar installation at the Denver Museum of Nature and Science today before signing the stimulus bill into law. Obama's team was joined by representatives from Namaste Solar Electric, Inc, a Colorado-based employee-owned solar electric company.

If you don't pay your own electric bills, you can find out, more or less, by checking out the EIA website, which gives, plus or minus this or that, the retail price of electricity.

Researchers at Rensselaer Polytechnic Institute have discovered and demonstrated a new method for overcoming two major hurdles facing solar energy

Researchers have created a new material that overcomes two of the major obstacles to solar power: it absorbs all the energy contained in sunlight, and generates electrons in a way that makes them easier to capture.

A recent partnership between the steel industry and UK university researchers has led to the development of a unique photovoltaic paint that can be applied to steel.

Revisiting a once-abandoned technique, engineers at the Massachusetts Institute of Technology (MIT) have successfully created a sophisticated, yet affordable, method to turn ordinary glass into a high-tech solar concentrator.

Ask any scientist to name Earth's most abundant source of energy, and the answer comes quickly: sunlight. In one hour, the sun strikes Earth with enough energy to power the entire planet for a year.

A cheap alternative to silicon solar cells can be found in dye-sensitised solar cells. This type of cell imitates the natural conversion of sunlight into energy by, for instance, plants and light-sensitive bacteria.

A diverse committee of experts from around the world, convened at the request of the National Science Foundation (NSF), announced 14 grand challenges for engineering in the 21st century that, if met, would improve how we live.

Learning how to control the movement of electrons on the molecular and nanometer scales could help scientists devise small-scale circuits for many applications, including more efficient ways of storing and using solar energy.

Steel forged railroads, skyscrapers and the automobile industry. Now it may help solar energy become cheaper and more widely available. In a study scheduled for the March 20 issue of ACS' weekly Journal of Physical Chemistry C, Finnish scientists report an advance in replacing the single most expensive component of a cutting-edge family of solar cells with less costly material.
