Pacific Gas & Electric is planning two massive solar projects, 250 & 550 megawatts. Working with Optisolar and Sun Power Corporation PG&E hopes to meet its 20% target for renewables with these plants. Just how big is that 550 MW project? Nine square miles!

A two-part article about solar electricity, the first one focusing on photovoltaic electricity.

Sun Run has come up with a "solar as a service" model, where you don't need to buy the panels, they install and maintain them, and you just pay a low monthly utility. Could this be what gets solar out there far and wide?

 Developing organic solar cells from polymers is a cheap and potentially simple alternative energy. New Jersey Institute of Technology's Dr. Somenath Mitra has developed solar cells that use a carbon nanotube complex. Nanotubes are 50,000 times smaller than a human hair, but one nanotube can conduct a current better than any electrical wire.

California city and state officials are making residential solar panels cheaper for homeowners with some creative incentive programs.

I recently came across a very unique photovoltaic product, in fact it is quite amazing. It is based on amorphous(non-crystalline) silicon photovoltaic technology, making it ideal for both power generation and controlling light and heat.

Bikini season is almost here. How about a photovoltaic bathing suit to charge your iPod?

The Voltaic Generator, due out the end of April, is the first carrying bag with solar cells powerful enough to recharge a laptop computer.

An article comparing price, efficiency and the environmental impact of different solar panels.

The Cool Earth Solar balloons are a hot new product being developed to deliver renewable energy cheaper than current natural gas power plants.

Quantum dots by photovoltaic and semiconductor company Spire, Incorporated could be the key to cheap solar energy.

I have the privilege to show to the public: the first ever official electricity bill , that come from a green energy installation for pubblic lighting. A copy of the bill it is even available for download - (just click the red sentence at the bottom of their blog page.) that show the huge saving of money that has been collected by the town of Torraca,

This is the 11th in a 15+ series of articles by a home owner on his experiences from participating in the ecoENERGY Grant program.

In this article, the home owner discusses the solar energy recommendation and what he was able to discover on its practical implementation.

Solfocus is building a 500 kw concentrator photovoltaic power plant in Spain that it believes will be disruptive technology for the rest of the solar industry.

Lawrence Kazmerski, Director of the National Center for Photovoltaics, discusses the prospects of solar-photovoltaic (PV) technologies, arguing that this solar-electricity source is at a tipping point in the very complex realm of worldwide energy. Kazmerski discusses how recent research and development advances in areas such as solar
