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.
