Do you agree or disagree:Renewable sources of energy (sun, water, wind) can replace fossil fuels such as gas, coal?
Introduction
Although human being use traditional fossil fuels a lot, renewable fuels will be more beneficial for out 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 that fossil fuels will be instead of renewable energy because of being environmentally friendly, cause less pollution, and have an unlimited supply.
Body I [Environmentally friendly]
First of all, Global warm phenomenon is being considered by scientists. According to the Discovery reference, the Green house is caused by the excessive output of CO2, on the other words, the paramount reason is that coal and natural gas is overusing in manufacture area, producing area and normal human being life in the past. Although traditional sources of energy are close to human being life, they are making the environment of human being worse than before. Regrettably, human being should focus more on the usage of new energy as possible as we 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 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 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-the limited supply of energy. The traditional energy will be exhausted soon or later, according to scientist’s prediction. As we known, traditional normal resources such as coal, wood and gas are given as gift by earth. The form of them must be waiting for 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 form. It is fact that the renewable energy replaces the traditional energy and makes the life of human being 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 exhausting the coal.
