* The price of photovoltaic (PV) solar power panels has dropped 200 percent over the last 30 years, according to the Department of Energy. Owners now pay between 10 and 40 cents per kilowatt-hour.
* A study by the U.S. Department of Energy (USDOE) showed that solar power conditions were close to perfect (99 percent) in San Francisco on June 14th, 2000. On that day, 100,000 customers in that area lost power. Solar power could have provided all they needed.
* Another USDOE study showed that the roofs of California's city and county buildings, if covered with solar PV panels, could generate 200 megawatts of clean electricity! Cover California's school roofs with solar power panels, and you add 1,500 megawatts more to the state's peak power supply.
* In California, covering every available commercial and industrial roof with solar power panels could generate all of the electricity needed in that state during the daytime.
* Germany is making the best use of solar power, even though its climate includes many cloudy days.
* It takes only about 8 minutes for solar energy to travel from the sun to the earth.
Suggestion for school teachers: Have a contest to see which group of students can unearth the most fun facts on solar power.
