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. Another source of energy from nature is the wind which is clean and plentiful. Energy from the wind has been used for centuries to move ships, grind grain, pump water and do other forms of work. In recent time, wind has been used to generate electricity. Water can also provide power. For a long time, people have used water to power machines. Some early uses of water were to mill grain, saw wood and power machinery for the textile industry. Today water is mostly used to generate electricity. 28. The fossil fuels on earth are ....................... A. unlimited B. being used up C. renewable D. not uesd now 29.

Most of our electricity comes from the use of coal, oil, water power and nuclear power. We are looking for a cheap and clean source of power. Solar energy can be cheap and clean because it is available and it doesn’t cause pollution. One percent of the solar power that reaches the earth is enough to provide power for the total population. It is possible to store energy for a number of days, so solar energy can be used on cloudy days. Many countries in the world are beginning to use solar energy. By this way, we can save natural resources.

The more waste we produce, the more disposal trucks, labor and dump space are needed. All these cost money. That’s why we must learn to use less, and to reuse and recycle so that less waste is produced. Recyclable wastes include paper, glass, plastic and metals. When you go shopping, do not buy over-packaged products. If you have to buy heavily packaged products, do not throw away the packaging, use it for another purpose. For example, paper bags can be used for carrying other things, or for mak...

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.
Natural resources will never run out.
A. True
