We are looking for cheap, clean, and effective sources of energy. These types of energy won’t cause pollution or waste natural resources. It will be provided freely by the sun. One percent of the solar energy that reaches the earth will be enough to provide electricity for the whole population of the world. Solar energy will be used by many countries around the world. Solar panels will be placed on the roofs of houses and other buildings and the sun’s energy will be used to heat water. The energy will be stored for a long time. We hope that by using solar energy the problem of the energy shortage will be solved.

1. What types of energy are we looking for?

 _We are looking for cheap, clean, and effective sources of energy

2. What will we use the sun’s energy for?

 _____ The sun’s energy will be used to heat water

3. How long will the energy be stored?

 __________The energy will be stored for a long time

Renewable energy sources wind and solar energy will be used to solve the problem of pollution.

Renewable energy sources wind and solar energy will be used to solve the problem of pollution.

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, 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 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. Sweden has an advanced solar energy program. There, all buildings will be heated by solar energy and cars will use solar energy instead of gas by the year 2015.

True or False sentence:

1...........T.........Solar energy can be cheap and clean.

2........F............Most of our electricity now comes from nuclear power.

3..........F..........the solar energy that gets to the Earth cannot provide enough power for the world's population.

4..............T......Solar energy can be used on cloudy days.

5...........T.........All buildings in Sweden will be heated by solar energy in 2050.
