Read the passage, then answer the questions below

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 the Sun.

At present, most of our electricity comes from the use of coal and gas, oid 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 roofs 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.
