8月31日 新能源(sun, wind, water)will be soon replace 旧能源fossil fuels (oil, gas), agree or disagree? 2006 年10 月28日技术进步类 改作业的人辛苦了!一起加油!!:handshake
At present, the international community and our nation are focusing on the environment around our lives. People and related organizations would discuss this issue firstly when they need to chose which city or country should have an international conference, where the delegates from each nation will appear. Therefore, I definitely agree that the new energy will replace the old ones for the reason that it will not bring the pollution as the old energy did.
In the first place, fossil fuels led to industrial and atmosphere pollution. At the beginning of the developing industry, coal and fossil fuels played a key role in running the machines and produce electricity. It resulted in both air and water pollution, though, people got progress in industry. At that time, the sky of some industrial areas was dark or red. This situation starts to change when some developed countries adopted new energy, like solar energy. From then on, people use solar energy when take shower instead of electricity or fossil fuels, because it will not make any dirt to the air.
Meanwhile, the water power—hydroelectric power does not bring pollution. In many counties, such power plants are used to produce electricity. The falling water is pushing the turbines to run every machine for families and factories.
At the same time, some developed countries could be examples to developing nations when they utilize the new energy to reduce the pollution and to enhance national ability. At present, environmental protection is one of the main issues people are interested and care about. Development and pollution became a controversial topic in society. The old energy has brought a lot waste and the phenomenon of oil leakage made plants and animals died, which broke biological circle. Those developed countries realized that the serious consequence while developed their industry. They may have better methods to ameliorate it. For instance, the solar energy and hydroelectric dam are adopted in developed nations first.
In conclusion, the new power will replace the situation of the old ones soon, because of the limited old energy and the pollution they brought. Meanwhile, people need to utilize the new energy better to improve the living condition. |
