History of solar energy - "Solar Power – Fun
Facts"
Fun facts about solar power are popular at any age.
People want serious information about solar power, but sometimes, even the
serious can be expressed in fun facts.
Fun facts on solar power
include things such as the fact that, in a single hour, enough sunlight
reaches the earth's surface to meet the entire world's energy needs for a
full year. Imagine! That information comes from the American Solar Energy
Society.
Here are some more fun facts on solar power.
12 Fun
Facts on Solar Power
* As early as 1921, the Nobel Peace Prize was
awarded for experiments with solar
power and photovoltaics. It was awarded
to Albert Einstein.
* When silicon is taken from just one ton of
sand, and used in photovoltaic solar
power panels, that silicon can
produce as much electricity as 500,000 tons of
burning coal.
* In
the U.S., there are more than 10,000 homes that get their energy entirely
from solar power.
* Nearly 200 years ago, a British astronomer by
the name of John Herschel
cooked food with solar power during an journey
to Africa.
* California opened its first large solar power plant in
1982.
* Solar power can cut water bills by more than 50 percent
each year in a home
where a solar model replaces the electric water
heater.
* 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.
