9. How to Solve Energy Crisis
Man is faced with a grave problemthe energy crisis, which is becoming increasingly serious. First, with the increase in the worlds population, the demand for fuels is growing steadily. Second, the rapid development of industry and agriculture calls for an increasing amount of coal, oil and natural gas.
Confronted with the energy crisis, we should take a series of effective measures to save energy. For one thing, it is high time that people all over the world realized the severe fact that our natural resources have been fixed since the earth was created. For another, the governments of all countries are supposed to lay down the rules and regulations to restrict the amount of gas used by cars. Finally, scientific researches should be encouraged to work out efficient methods of saving fuels and to seek new sources of energy.
Personally, I believe that solar energy is a possible source of clean, inexpensive and abundant energy. It does not pollute the environment and costs only as much as the installation of solar panels to absorb the suns rays. Consequently, Im confident that a bright future is awaiting us because solar energy will be able to help us to solve the energy crisis.
