“Are you sure 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 coutries are ready 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 days , so on cloudy days you can use solar energy , too.
Sweden has an advanced solar energy and cars will use solar power instead of gas by the year 2015”
