Are you looking for a cheap, clean, effective source of power that doesn’t cause pollution
or waste natural resources? Look no further than solar energy from our sun.
At present, most of our electricity comes from the use of coal, gas, oil or nuclear power.
This power could be provided by the sun. One percent of the solar energy that reaches the Earth
is enough to provide power for the total population. Many countries are already using solar
energy . Solar panels are placed on the roof of a house and the sun’s energy is used to heat
water. The energy can be stored for a number of days, so on cloudy days you can use solar
energy, too.
Sweden has an advanced solar energy program. There all buildings will be heated by
solar energy and cars will use solar power instead of gas by the year 2015.
