A lack of electricity

At present there is a heavy shortage of electricity all around the world. Maybe some night while you are doing something important, but suddenly the lights are off. What an indignant thing! Then, we could ask what has happened and why.
　　There are many reasons for lack of electricity in our world. I'll give two main ones. First of all, to make electricity needs plenty of natural sources, such as coal, water and wind. Unfortunately, there are fewer and fewer natural resources left because they are always limited but more and more people need it. It has become the basic factor for economical and social development. Secondly, many of us haven't paid enough attention and even still waste much of it. What a shame!
　　So, we should take quick and informed action to solve this problem. Of all measures, the below are the most important: We should develop more ways of making electricity such as nuclear energy, and form the good habit of efficiently making use of our limited but valuabe resources!
