Is Green Energy Viable?

[cmacq]

Right,
Your quite right. I live in the US southwest, and solar has been in use here, a variety of types at a variety of scales for quite a while now.

Also here are the basic stats on a few US solar plants.

Solar Thermal Energy Plants; proposed and operational
Solar Company & Electric Utility: BrightSource Energy and Pacific Gas & Electric. PLant Location: Mojave Desert, USA.
Megawatts: 500 MW, with plans to expand to 900 MW.
Status: Scheduled to be operational in 2011.

Solar Company & Electric Utility: Stirling Energy Systems and San Diego Gas & Electric. Plant Location: Mojave Desert, USA.
Megawatts: 500 MW, with possible expansion to 850 MW.
Status: Will be operational in 2011.

Photovoltaic (PV) Solar Power Plants; proposed and operational
By 2011, Deming, New Mexico, USA will be the home of the world’s largest solar power plant. This 300 Megawatt solar facility will be 15 times the size of the current largest solar plant on the planet. New Solar Ventures and Solar Torx are the companies behind the project. The solar energy plant will cover as many as 1,300 hectares and employ between 300 and 400 people. The project’s planners estimate that the plant will supply enough energy to power 240,000 homes.

The Solana solar plant, 70 miles from Pheonix, near Gila Bend, Arizona, USA, will compliment the Deming plant when both begin operations in 2011. It will produce 280 megawatts of energy, provide 1,500 jobs, and cover an area of 769 hectares. The solar power facility will be the child of Abengoa Solar and Arizona Public Service Company. However, the project depends on the United States Congress to renew clean energy tax credits, which would otherwise expire at the end of 2008.

An 80 megawatt solar farm in Fresno, California, USA will be completed by 2011. Cleantech, together with the California Construction Authority, will be responsible for construction. When finished, the plant will occupy about 260 hectares. It will be called the Kings River Conservation District Community Choice Solar Farm. In addition to this solar farm, Cleantech is in the preparing to develop several other facilities of a similar size also in California.

Las Vegas, Nevada, USA 14.2 megawatt solar park operated by SunPower. It’s located at the Nellis Air Force Base, which it powers. Saves the Air Force base an estimated $1 million USD annually in energy costs. The solar array covers an area of over 56 hectares and employs 70,000 PV panels.
