There has long been the hope for renewable and alternative sources of energy and some people think it is still imaginative for the renewable energy to considerable replace the currently prevailing fossil fuels. They argue that the lower cost and lower efficiency of the renewable sources of energy than fossil fuels hinder wide spread usage of them. However, I strongly believe that renewable energy will replace fossil fuels soon because of both the imperative needs to preserve the environment and and the technology improvement at a speed of lights.
To begin with, the recent and strong movements for environment preservation from many countries around the world will reduce the amount of usage of fossil fuels. This is because most people are now very well aware of the severity of environmental pollution that comes largely from the overuse of fossil fuels and they want to live in more favorable surroundings and give it to the next generations. To be specific, consumption of fossil fuels like gasolines and charcoals produces greenhouse gases and smogs which have significantly negative influences on the global climate by increasing the temperature of the earth. These gases such as carbon dioxide and nitrous oxide are emitted by the vehicles and plants powered by fossil fuels. In order to decrease the risk of the environmental distruction in the future, many countries drew an agreement on the limitation of the amount of emission of carbon dioxide and abide by related rules. Even charging proportionally to the volume of carbon dioxide is now in act. From these kinds of efforts, the usage of fossil fuels will be probably reduced by substantial amount soon in the future.
What’s more, state-of-the-art technology will enable the renewable sources of energy to be cheaper and more efficient, which will lead to the remarkable replacement of fossil fuels. The speed of development of technologies which are related to the renewable energies is incredibly accelerating to the extent that many people are even not able to recognize it. For instance, some peple still think that the hydrogen-powered vehicles are not yet useful due to the heavy weight of the specially engineered engine as well as the risk of explosion derived from the unstable nature of hydrogen. However, the enthusiastic scientists and engineers came to develop smaller and more stable engines, increasing the possibility to be purchased and used by more and more people. In this sense, to thank to the endeavors of the technicians and engineers, most people will be able to change their motors from ones powered by fossil fuels to hydrogen cars in near future. This is because the less the amount of the fossil fuels remain, the higher their price will climb.
To conclude, it can be surely expected that fossil fuels will be replaced by renewable sources in near future. The rationale behind this expectation is that the environmental movement will curb the abuse of fossil fuels in order to reduce the greenhouse gases. In addition, the recent technology for renewable energy will provide people with the opportunities to use vehicles driven by cheap and safe hydrogen engines. If had not been for the enormous efforts of the engineers, people would have waited for commercialization of renewable resources longer than now. |
