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.

Many people still believe that natural resources will never be used up. Actually, the world's energy resources are limited. Nobody knows exactly how much fuel is left. However, we also should use them economically and try to find out alternative sources of power. According to Professor Marvin Burnham of the New England Institute of Technology, we have to start conserving coal, oil and gas before it is too late; and nuclear power is the only alternative. However, many people do not approve of using nuclear power because it's very dangerous. What would happen if there was a serious nuclear accident? Radioactivity causes cancer and may badly affect the future generations. The most effective thing is that we should use natural resources as economical as possible

Cars will use solar power instead of gas in Sweden by the year 2015.
OR: In Sweden, cars will use solar power instead of gas by the year 2015.
Part : T (true) or F
We can develop alternative sources of energy, and unless we try we'll never succeed. Instead of burning fossil fuels we should be concentrating on more economic uses of electricity, because electricity can be produced from any sources of energy. If we didn't waste so much energy, our resources would last longer. We can save more energy by conservation than we can produce for the same money. Unless we do research on solar energy, wind power, tidal power, hydroelectric plants... our fossil fuels will run out and we'll all freeze or starve to dealth. Several countries are spending much more time and money on research because the energy from the sun, the waves and the winds last forever. We really won't survive unless we start working on cleaner and safer sources of energy.
1. Fossil fuels are renewable sources of energy F
2. Eletricity can be produced from the sea T
3. The energy from the sun, the waves, and the winds will never be used up T
4. We really need to worry about cleaner and safer sources of energy T
5. What is the passage mainly about?
A. We are facing huge lack of energy
B. Electricity is the main energy we use
C. Altenative sources of energy must be developed
D. It is impossible to have safer sources of energy
6. Which source of energy cannot last forever?
A. coal B. wind C. water D. waves
