How to Solve the Energy Problem
When asked about one of the biggest problems today, many people say would that an energy crisis is approaching and is threatening mankind's survival. They are afraid that the world is likely to run out of oil and metals and even to run short of food.
To this problem, most countries respond with the demand for more rigid conservation of our natural resources. Indeed, this is urgently needed, since the present waste of energy is so serious. If the natural resources are used economically, we can certainly slow down the present drain on the limited energy supply.
However, the problem cannot be solved by conservation only. I think another way is to develop new energy resources. Obviously, no matter how hard we try to save energy resources and how abundant they are, we will use them up sooner or later. I think we don't have to depend only on the current energy resources. There are many other energy resources that we can develop such as nuclear power, water power and solar power. If so, these resources can completely replace the conventional energy and thus solve the problem of energy crisis. (188 words)
