2021年下半年大学英语四级作文必背范文：能源危机
写作题目：能源危机
The global financial crisis hit the world in 2008. Many countries, especially America and European countries got into a terribly gigantic financial mess. With energy prices such as oil going up and down dramatically, a new round of international meetings concerning the promotion of renewable energy was kicked off. American President Obama even made plans to spend billions of dollars on renewable energy. Do you think renewable energy is a feasible way to solve the energy problem?
写作范文Renewable Energy Is the Way to Go
With the skyrocketing demand of oil, coal and natural gas, we are confronted with an energy crisis since energy resources such as gas and oil are fast diminishing this century, One remedy fo a this problem is the implementation of a renewable energy policy. As far as I am concerned, renewable energy can serve as an effective way of solving the energy crisis.
Firstly, renewable energy has unlimited availability. Traditional energy resources, such as coal, oil and natural gas are non-renewable, which means that the world will eventually run out of them, constituting the main threat to energy resources. However, generated from natural resources-such as sunlight, wind, rain, tides and geothermal heat, renewable energy is continuously being replenished by nature on a time scale appropriate to human use. Furthermore, with advancing technologies, renewable energy will be able to supply a significant proportion of the world's energy needs, making it possible to overcome the energy crisis. Secondly, renewable energy has many immediate environmental benefits. The use of fossil fuels-coal, oil and natural gas has affected the environment by polluting the air and water, creating toxic wastes, and causing global warming. However, renewable energy resources are clean. Their use can avoid these negative environmental impacts and risks, and moreover, it can help conserve fossil resources for generations to come.
Concerning the two main advantages of renewable energy, I personally hold that they are a feasible way to solve the energy problem. (240 words)
