One percent of the solar energy that reaches the Earth is enough to provide power for the total pollution. Many countries are already using solar energy. Solar panels are placed on the roof of a house and the Sun's energy is used o heat water. The energy can be stored for a number of days, so on cloudy days you can use solar energy.
