Topic:Renewable resources of energy (sun wind water) will soon replace fossils fuels such as gases, oil, and coal.
If you are a serious observer of life, perhaps you have found the phenomenon that more and more renewable resources of energy such as sun, wind and water be opened up and utilized, they occupy the rate of resources higher and higher and government encouraged used renewable resources which has caused wide public concern by people. However, there still large number of people gain energy from fossils fuels such as gases, oil, and coal. Moreover, I baldly deem that most people will depend on fossils fuels in a long-period will soon replaced by new resources undoubtedly.
Frist of all, I ackownledge the fact that renewable are widely held and its are indeed more advanced than fossils fuels. They are less pollution comsuming, less labour comsuming, easier to made and so on so forth. But all of these benefits have a prerequisited: we need dive a mass of money into manufacture new equipment. We cannot overlook a fact that there are millions of people who still have a miserable life and have to face the dangers of starvation and exposure. Government have responsibility to figure out this question frist rather than develop new resources and any government which is blind to this point may pay heavy price. Though the society is developing in an incredible speed, I do not believe that every government have abundant strength to shoulder responsibility of develop renewable resources of energy, in other word, it is impossible that people will not use fossils fuels anymore for the objective situation.
Even if there is no such an objective limitation, some objective reasons will make many people keep gain energy from non-renewable resources. Because of the limitation of science and technology, make the development of application of renewable resources of energy still very unripe. People prefer to choose non-renewable resources which pollution to be heavy, but reliable rather than renewable resources of energy which favorable to the environment, but more expensive. Fossils fuels whose history spanned thousands of years are the most traditional way for people to get energy. It is a kind of custom that is not so easy to disappear completely. For instance, when the solar energy came into people’s life, many experts predicted that it will replace coal. However, the result is we can still used coal nowadays.
No matter for the objective cause or the subjective reason, the fossils fuels will not disappear after sever decades, not to mention 20 years. therefore, I totally believe that students will still use printed books many years later., not to mention be replaced completely by renewable resources of energy, therefore, I totally believe that fossils fuels such as gases, oil, and coal will still be used many years later. |
