Tape Transcript:
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 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 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.
