About solar energy? i wanna have the newest information about solar energy,specaily solar plant that can work in cloudy weather t this is an article in Scientific American about a proposal to convert the U.S. electric grid into almost all solar by 2100, 65% by 2050,
using solar thermal and concentrating PV solar power plants in the U.S. southwest.

%26quot;Solar is one the most land-efficient sources of clean power we have, using a fraction of the area needed by hydro or wind projects of comparable output. All of America%26#039;s needs for electric power – the entire US grid, night and day – can be generated with Ausra%26#039;s current technology using a square parcel of land 92 miles on a side. For comparison, this is less than 1% of America%26#039;s deserts, less land than currently in use in the U.S. for coal mines.%26quot;

%26quot;Solar thermal power plants such as Ausra%26#039;s generate electricity by driving steam turbines with sunshine. Ausra%26#039;s solar concentrators boil water with focused sunlight, and produce electricity at prices directly competitive with gas- and coal-fired electric power.%26quot;
from Ausra%26#039;s website

Green Wombat has several articles on solar thermal plants being built in California.

Here are links to some solar thermal companies. there are a few more.

Here%26#039;s a company at or near the cutting edge in thin film PV
http://www.nanosolar.com/

other thin film companies are
United Ovonics Solar (claims good performance in less sunny areas)
First Solar
Emkor
Heliovolt
Open Energy

Evergreen Solar( unique string ribbon technolgy)
Sunpower has the most efficient cells

• Any solar cell can work in cloudy weather. It will make less power but not zero power. If you want complete information consult wikipedia. If you think wikipedia is not reliable, then check their sources. All wikipedia articles give links to other web sites that are NOT part of wikipedia where they got their information.But it will take more work than just asking a question here. You need to read articles, then click on the links in them to find other sites, and use google to look up words or phrases, and you need to build up a network in information in your mind. In other words, you need to do RESEARCH.
• The sun is the leading cause of global warming. By encouraging the use of solar energy, we are encouraging the sun to continue getting warmer and warmer until the earth will be so warm that many penguins and polar bears will die. I recommend the use of fossil fuels, since they are made from dinosaur bones, and since dinosaurs are all dead, its not really that big of a deal if we burn up all the fossil fuels. Thanks for taking an interest in saving mother earth!!!
