Energy crisis, one of the most serious problems, which Mankind will be faced with in the new millennium, causes more and more concerns. Someone think that among all the alternative energies, nuclear power should be the most suitable. But others argue that the safety of making use of nuclear power is still far from satisfaction. As I see it, both opinions have their own merits.

As we known, nuclear reaction can release great energy in a small instant. According to this theory, nuclear power station can provide us with sufficient and cheap electricity. What's more, this way of generation may be the most efficient in all ways we have mastered so far. Because one kilogram uranium, the main material of nuclear power station, can produce thousands of times as much as what one kilogram coal or oil can generate. Also compared with traditional fuel - coal, gas or oil, uranium is so adequate on the earth that we would not encounter the problem of shortage of fuel in many centuries.

However, a coin has two sides. Although during the generation in nuclear power station no smoke or harmful gas is given off, the radioactive rubbish remains the biggest problem presented in front of nuclear experts. Usually this rubbish sealed in metal containers is buried deeply in the earth where people seldom come. The radioactivity of rubbish still costs thousands of years or even longer to be reduced to the harmless level. Nobody is sure how much it will damage the environment surrounding it. The safety of generation procedure is also a big problem. Any careless may result in such a terrible consequence as the issue of.

In general, the technology of nuclear power still has much to be improved. With the development of science and technology, I'm sure the day of safe utilization of nuclear power is coming soon. (309 words)
