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. * Practice 1: Rearrange the groups of words in a
