Recently petrol’s price is increasing sharply, and this draws people’s great attention to petrol and its substitutes. However, for engineers and scientists, energy problems have been a long and great concern since the end of 20th century. For the following 21st century, engineers and scientists will need to do more to meet increasing demands with limited fossil resource. This essay will focus on the limitation of fossil resource, the technology of improving the efficiency and the bright prospect of new resources.
As we all know, the fossil resource, including petrol and coal, is limited. Firstly, it usually takes millions of years to form such resources from the bodies of dead animals and plants. Thus, it is almost impossible to have more fossil resource within the survival of human beings. Secondly, for thousands of years, our main energy comes from the fossil resource. Especially for hundreds of years after industrial revolution, the consuming speed is greater and greater. As a result, the fossil resource left is very limited.
Faced with limited fossil resource, we need to improve the efficiency of using it to get the maximum energy. For example, we can convert solid coal into powder to burn more efficiently and gain more energy. Another example is mixing petrol with alcohol, which is wide spread in some parts of China, and feedback is quite good.
Because of limited fossil resource and increasing demands, we have to develop new resources. Among new resources, sunshine and nuclear fusion are accessible and popular. We can get huge energy from these two resources, if we find proper and efficient ways to make full use of them. Certainly, it is we engineers’ duty to accomplish it. Besides great energy, these two resources are clean, which means they do not generate any toxic gas, liquid or solid.
In conclusion, as engineers, we will shoulder the duty of improving efficiency of using resources and developing new resources. To achieve this target, we should study and work hard from undergraduate studies.

First of all, you are deserved to be a chemical engineering student, who never forgets to share some knowledge about chemistry with us.However, I am afraid oil is mainly made from the remainders of aminals or fish.It has little to do with plants. In my knowledge of earlier, mine is made from the remainders of plants.All in all, you have done a good work.
