而相对应的可再生资源,像水力,风能,潮汐能和太阳能,又因规模受到环境,季节,地理环境等条件的限制,而且现在的开发技术不足,很难得到充分利用。
核能因为在地球中储量丰富,像海水中氘,有两千多亿顿,可用上千亿年,矿石中的铀能用2000多年。
而且所释放的能量比全世界所有能量综合还要大上千万倍,被称为“无穷的能源”。
Because of the limitation of traditional fossil energy reserves, people pay great attention to nuclear energy. Now there are over 6 billion people in the w orld, which is more than three times of that in the 19th century. And there are more than 16-fold increase in energy consumption. According to the current consumption level, the oil w ill be used up in 46 years, natural gas w ill be used up in 65 years, and the coal is onl y enough for over 200 years. How ever, it is di f ficult to make full utilization of the corresponding renewable resources such as hydro, w ind, tidal and solar energy in that the scales of them are limited by environmental, seasonal, and geographical conditions. Besides, the lack of development technology i s also a problem. Nuclear energy is abundant in the E arth, for example, there are over two hundred billion tons of deuterium in sea water. It could be used for hundreds of billions of years i f its great changes can be controlled. Uranium in ores can be used for more than 2,000 years. And the energies they release are million times of that of the integration of all world's energy, w hich is known as the "infinite energy."下图是非污染能源的结构比例,其中核能占绝大部分,占百分之70,因此核能也被称为最安全最清洁,经济效益最高的电力资源。

They say that Nuclear energy has many economic benefits:
What we want to say is that the nuclear power plant will cost a lot of money. To build the nuclear power plant will cost much money, to operate and maintain the nuclear power plant will cost much money, and to dismantle the nuclear power plant will also cost a huge amount of money. In 2013, Levy nuclear plant, a nuclear power plant in American put off its use of nuclear energy. Levy nuclear plant attaches to Duke energy, a sustainable electric and gas company. The statistic of Duke energy shows that Levy nuclear plant is more costly than a natural gas facility. It is said the levy nuclear plant cost 13.9 billion while the natural gas facility cost 10.1 to 12.6 billion, depending on the fuel. It shows that to operate a nuclear power plant does not save much money, and it even cost more money in some case, like the levy nuclear plant. The Times analysis found that the assumption that the Levy project will save money, or save customers’ money only if its believers ignore the massive price tag of building a nuclear plant, but it is a fantasy because there is no free nuclear power plant can appear magically. And even the Duke energy say so.
They say that Nuclear energy has abundant reserves:
What we want to emphasis is that the resources of developing nuclear energy is not so rich as what they say. Uranium is a necessary element when develop the nuclear energy, but uranium is a scare resource, a limited resource. Unlike fossil fuels which are available to most of the countries, uranium exist in only few of the countries, so most of the countries rely on other countries for the constant supply of this fuel. It is mined and transported like any other metal. Supply will be available as long as it is there. Once all extracted, nuclear plants will not be of any use. Due to its limited supply, we can not say the nuclear energy development has abundant resources, on the contrary, we even lack some kind of the necessary resources to develop it.
They say that Nuclear energy is easy to transport:
But we want to emphasis that it needs high technology, and there are potential risks when transport it.
Conclusion:
Since the nuclear energy has so many disadvantages, we have to stop developing nuclear energy. What we need to do is to focus on the development of other new clean energy, renewable energy, such as hydro-energy, solar energy, and wind energy. We can not develop the nuclear energy at the cost of people’s safety, the country’s safety, and even the whole world’s safety. We can not pay less attention on these potential risks, we need to do something to prevent the danger from happening.。
