摘  要在当今社会，电能已经走进了家家户户，千家万户都享受着电的便利，手机、电脑、厨具、烧水、洗衣服、看电视等等事物，似乎在我们身边的每一样事物都已经离不开电能。科技的发展使各类用电器变得五花八门，全球电量的使用也变得更加紧张，大家对电能的需求量呈现出爆炸性的增长趋势，无论是生活生产还是工业制造。于是人们通过不断的发展科技，寻找到了多样的不同发电的途径，同时也逐渐改变了电能发电来源的比例配置，新能源很快在电力行业崭露头角，虽然目前使用最广泛的仍然是火力发电和水利发电，但是新兴能源中的太阳能发电、风电、地热能发电、潮汐能发电等等和核能发电在世界的脚步已经开始奔跑。89405

在世界和平的年代里，核能已经成为发达国家的主要供电来源。 中国目前的核能已经有9处左右，但是在世界范围中，这个还是很小的一部分。有些发达国家的核电事业已经达到一般以上了，比如美国。但是核电的危害也是非常大的，一旦出现核燃料泄露，周边的环境乃至整个城市都会陷入灾难，因此核能的利用也是让人思考的。

对于太阳能电池板发电供电而言，这种新型的，节能环保型的供用电方式占总供电来源的规模也快速增加，虽然当下的转化率还不是很高，前期投入也比较大，但是能利用太阳光这种清洁、安全、可再生的供电方式必将成为未来可持续发展的主流，也随着各国对太阳能供电的扶持力度的加大，太阳能供电也必将迅速崛起，估计在未来的10-20年，太阳能发电供电的比例将提高到总供电比例的40%以上；未来的50年至80年将超过60%的比例。

Abstract In today's society, electric power has entered every family, thousands of households enjoying electric facilities, mobile phone, computer, kitchen, heating water, washing clothes, watch TV and so on things, everything seems to be in the US are already cannot do without electricity。 The development of science and technology makes use of a wide variety of all kinds of electric power becomes, the world has become more intense, people's demand for energy increases explosively, whether it is life or industrial production。 So people through the development of the science and technology, to the different ways for power generation, but also gradually changed the allocation of electric power sources the proportion of new energy in the electric power industry quickly emerged, although there is still the most widely used in thermal power generation and water power, but the new energy in solar power generation, wind electricity, geothermal power, tidal power, nuclear power and pace in the world has started running。

In the era of world peace, nuclear power has become the main source of power in developed countries。 China now has about 9 nuclear power, but this is still a small part of the world。 Some developed countries have reached more than general nuclear power, such as the United states。 But the danger of nuclear power is also very large, once the emergence of nuclear fuel leaks, the surrounding environment and even the whole city will be in a disaster, so the use of nuclear energy is also a reflection。源Q于W优E尔A论S文R网wwW.yOueRw.com 原文+QQ75201,8766

The solar panel power supply, the new power supply mode, energy saving and environmental protection of the total power source scale increases rapidly, while the conversion rate is not very high, the initial investment is relatively large, will supply but can use the sun to this clean, safe, renewable and sustainable future become the mainstream the development, along with the increasing support for solar powered countries, solar power will rise rapidly, estimated in the next 10-20 years, solar power supply proportion will increase to more than 40% cases of the total power supply; the next 50 to 80 years will be more than 60% of the proportion。
