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?

Our non-renewable energy sources such as coal, oil, and natural gas will (1) _______run___ out of in the future. That's the (2) ____reason______ why we are looking for alternative sources of (3) _______energy___ which are cheap, clean and effective. These (4) ____kinds______ of energy will not cause (5) _____pollution_____ or waste natural resources. (6) _____Renewable_____ power is one of them. It's currently the cheapest source of large-scale renewable energy.
Most wind energy is produced from turbines that have three 60-meter-long blades. The wind spins the blades, which turn a shaft connected to a generator that produces (7) ____electricity______. Now, mass production and technology advances are (8) ______made____ turbines cheaper. In 2000, cumulative wind capacity (9) ____of ______the world was 17,000 megawatts. Fifteen years later, this number increased sharply to 430,000 megawatts. It is predicted that with this pace of growth, (10) in 2050 one third of the world's electricity needs will be fulfilled by wind power.
Almost all our energy comes from oil, coal, and natural gas. We call them fossil fuels. The earth’s fossil fuels are running out. What will happen when there is no coal, oil and gas on earth?
Scientists are trying to find and use other alternative sources of energy. We can use energy from the sun, the wind, and the water.
Solar energy is unlimited. The sun supplies all the energy used to grow plants, to evaporate water for rain, and to maintain the temperature of the planet. All are necessary for human life. If we are able to collect solar energy, we will be sure to have this abundant source of power.
