Solar Power~~~Cheap??  

Photovoltaic, or solar-electric, systems capture light energy from the sun's rays and convert it into electricity. Today these solar units power everything from small homes to large office buildings. In the 1980s the average price of energy captured with photo voltaics was 95 U.S. cents per kilowatt-hour. Today that price has dropped to around 20 cents per kilowatt-hour, according to American Solar Energy Society. But the cheaper rate is still more expensive than the average national price of electricity, which in 2003 was a little over 8 cents per kilowatt-hour.
Other recent advances include "thin film" photovoltaic technology; a high-tech coating that converts any surface covered with the film into a solar-electric power source. Boats and RVs that use the film are now on the market. The Indian Railways has set up solar panels on the roof of most of the railway stations.
Engineers have also developed a roofing material coated with the electricity-producing film. Somebody who puts this on the roof of a house also thus puts on the solar panels at the same time. The roofing material withstands inclement weather and, on bright days, taps sunshine for electricity. Most traditional photovoltaic solar units on the market today convert between 11 and 13 percent of the sun's light into energy. Engineers think they can improve on that to 17 percent in the near future.
In the last two decades solar-thermal panels,units used to warm household hot water, pools, and spas, have become highly efficient. Energy costs have decreased from 60 cents to 8 cents per kilowatt-hour since the 1980’s.
Friends, get ready to use them.
