Are you looking for a cheap, clean, effective source of power that doesn't cause pollution or waste natural resource? Look no further solar energy from the Sun
At present, most of our electricity comes from the use of coal and gas, oil or nuclear power. This power could be provided by the Sun. One percent of the solar energy thet reaches the Earth is enough to provide power for the total population
Many countries are already using solar energy. Solar panels are plaaced on the roofs of a house and the Sun's energy is used to heat water. The energy can be stored a number of days, so or cloudy days you can use solar energy, too
Questions
1. Is the solar energy an effective source os power?
=>Yes,it is
2.Where are the solar panels placed?
=>They are placed on the roof of a house.
3.Is the solar energy used in Vietnam now?
=>Yes,it is
