▶ Your Answer : Some people think that fossil fuels will not be replaced to renewable energy sources. However, in my opinion, renewable energy source will be used instead of fossil fuels soon because it is more eco-friendly and econimical. First of all, fossil fuels have negative effect on the environment. They emit harmful gas and exhaust when they are burned. This gas from fossil fuels destroys the ozone and worsens the global warming as well. On the other hand, renewable energy can get from nature in an environmental way. They don't release any gas or dust. According to a study conducted by National Environment Center in 2007, the biggest cause of the global warming is Co2 gas and any emission from vehicles or machines running by fossil fuels such as gasoline or oil. This shows that fossil fuels will be less used than renewable energy will be used in the future because of it's harmful influence on environment. On top of that, fossil fuels are limited so the cost will be too high to use it in the future. People are looking for even bucks cheaper energy. Thus if it is more accessible to use renewable energy, consumers will tend to use it because it costs only for building facilities, and people can use it forever. Compared to this advantage of renewable energy, fossil fuels should be extracted from the limited amount in the ground, and those are used too much even now. Therefore, it is natural to assume that it will run out soon. According to a rule of "Provide and demand," the cost of fossil fuels will be sharply increase in the near future. For example, the gasoline cost is much higher than it was in last decades, and there are many researches conducting already to use the renewable energy more economically and efficiently. This reveals that renewable energy will be utilized on instead of fossil fuels. To sum up, fossil fuels have more disadvantages over the ones of renewable energy such as the fact that it is non-environmental and has a tendency to increase the cost. For these reasons, I strongly agree the idea that renewable energy will replace gas or oil in the future for the better environment and people's desire to save money. |
