The surface of the Earth receives an amount of solar energy equivalent to roughly 10 000 times the worlds energy demand. Of course there isn’t always sunlight, but the solar panels can store the energy, and they are getting better and better at it. A solar panel converts one sixth of the sunlight into electrical energy. Although they also are getting able to turn more and more of the sunlight into energy, they are already so efficient that space isn’t much of an issue anymore. The area of solar cells needed to supply a family with electricity is usually much smaller than the roof of their house. And when including the land required for mining and excavation of coal, CPS-plants (power-plants that rely on solar energy) are more space-efficient than power-plants fueled by coal. Solar power is roughly fifty times as space-efficient as growing crops for bio fuels. And that’s just with the technology that currently is commercialized.

Just in time for Al Gore’s major renewable energy challenge Florida’s Public Service Commission has “unanimously and enthusiastically” approved plans to build USA’s largest commercial solar-power plant (so far, we hope). Two other facilities also got the green light by the committee and are due to go online around 2009.

SunPower has been chosen to construct the three solar plants in the state of Florida. Howard Wenger, senior vice president, global business units for SunPower, said that “these agreements confirm the growing trend in the U.S. to build solar power plants at a scale rivaling those in market-leading countries such as Germany and Spain.”

Here are some of the best Green videos of the week, collected by the Ecolive.TV community.

What is the Solar Energy?

This video is an amazing guide, to understand the source of the Solar energy.

So why are we using fossil fuel… big oil money? yes you may use it in class.
