Do you agree or disagree:Renewable sources of energy (sun, water, wind) can replace fossil fuels such as gas, coal?
Introduction
Although human beings use traditional fossil fuels a lot, renewable fuels will be more beneficial for our lives. Moreover, traditional fossils fuels trend to be limited after hundreds of year; renewable fuels have been considered more and more significantly by all over the world since the beginning of 20th century. I absolutely agree It seems clear that fossil fuels will be instead used of renewable energy because of being that they are environmentally friendly, cause less pollution, and have an unlimited supply.
Body I [Environmentally friendly]
First of all, the global warming phenomenon is being considered by scientists. According to the Discovery reference, the green house effect is caused by the excessive output of CO2, on the other words, the paramount reason is that coal and natural gas is overusing being overused in manufacturing areas, producing areas and in a normal human being's life in the past. Although traditional sources of energy are close necessary to human being life, they are making the environment of humans being worse than before. Regrettably, human beings should do not focus more on the usage of new energy as possible much as we they could.
Body II [Cause less pollution]
In addition, Renewable fuels have much less pollution than fossil fuels. For example, a solar panel produces no waste, whereas a coal plant contributes many tons of waste, especially in the atmosphere. Although toxic chemicals are used to produce solar panels, they are minimal in comparison than to a coal plant. Clearly, this renewable fuel is much healthier than fossil fuels.
Body III [have an unlimited supply]
Last but not least, renewable energy will solve the essential issue problem-the limited supply of energy. The traditional energy will be exhausted soon or later, according to scientist’s prediction. As we is known, traditional normal resources such as coal, wood and gas are given as gift by the earth. The form of them must be waiting for produced over hundred of years, even thousand of years. Although the traditional energy is not limited recently, they will be limited in the future. Luckily, the renewable energy can and will replace the traditional energy under the unlimited condition.
Conclusion
In conclusion, the benefits of using renewable energy are more than traditional energy’s in many ways such as the improvement of environment, the decrease of air pollution and the unlimited supply of its form. It is a fact that the renewable energy replaces the traditional energy and makes the life of human beings better.
Additional Example
For example, neon lights are shining the whole night in some metropolis so that they exhausted the electric power which was exchanged by burning coal.
