▶ Your Answer : It is often said that givne the fact that there are enough remaining fossil fuels we are able to use for a long time, we do not have to think about advance of renewable energy sourses. Howerever, I firmly believe that now is the time for us to seriously contemplate on substituting renewable energy sources for the fossil fuels, suggesting that in the future, the fossil fuels are going to be replaced with renewable energy sourses for two reasons: the rest amount of the fossil feuls is limited and renewable sourse is helpful for saving money and the environment. To begin with, with the advent and spread of renewable energy sourses such as wind and solar energy, people will not confront a problem in which they worry about the limited amount of fossil fuels. This is attributed to the fact that we knowing through it's name, the renewable energy is a almost perpetual and everlasting ones compared to the fossil fules. According to a study conducted by Seoul National University of Korea in 2009, the amount of fossil fues is so restrictive and limited that people only can use the fossil fuels for up-coming 50 years. The researchers showed that we should consider the limitedness of the fossil fuels and be prepared for it within the forthcoming half an century. This implies that in the future, we have no choice but to replace the traditional energy such as fossil fuels with renewable energy sources. In addition, considering the claim that utilizing renewable energy sourses will contribute to overcoming today's energy problems in terms of cost-effectiveness and environment, we end up replacing fossil fuels with renewable energy sources in the future. This is due to the fact that when governments and individuals increase the use of renewable energy sources such as solar energy, people can depend less on traditional energy sources such as fossil fuels which are running out, expensive. and even severely detrimental to the environment. For example, when I was in fifth grade, my father decided to install a solar energy heater at our house. The cost of the installation was much high, but it was fully offset by government tax breaks on eco-friendly energy. Moreover, we were able to save money which could have been wasted on the maintenance cost using gas every month. In the long run, using solar enegy allowed us to save money and the environment. In brief, it seems that we could not subsist well, if it were not for the fossil fuels because we are fairly used to utilizing the fossil fuels almost all places. In spite of this fact, the fossil fuels cannot help being replaced with renewable and alternative energy sources since the existing amount of them is capable of covering only short-term period and it is less cost-effective than the renewable ones, even damaging the environment. |
