analysis the advantages and disadvantages of various energy now today people put forward higher and higher requirements of energy, and to seek new energy has become the current urgent task faced by the human. The existing energy mainly include hydropower, thermal power, nuclear power, and solar energy Solar power ( 太阳能) Can refer to the heat of the sun, See the three ways of heat transmission: radiation) , main show is often said that the sun's rays. 】 Such as energy. Hydropower drawback: hydropower a large amount of land is submerged, could lead to ecological environmental damage, and once had large reservoir, consequence will be unimaginable, in addition, a country's water resources is limited, but also influenced by season. The disadvantage of thermal power, thermal power need some burning fossil fuels such as coal, oil 【 Fossil fuels also called fossil fuels, is a derivative of the hydrocarbon and hydrocarbon mixture, which include natural resources such as coal, oil and natural gas, is made up of dead organic matter and formed by the decomposition of plant in the ground, is non-renewable resources. 】 。 On the one hand, the less fossil fuel reserves is limited, the burning, are faced with the danger. On the other hand burn fuel will emit carbon dioxide and sulfur oxides ( The oxide (in the broadest sense of the 氧化物) Refers to the oxygen and another binary compounds, chemical elements, such as carbon dioxide ( CO₂） , calcium oxide ( CaO） And carbon monoxide ( CO） And so on. 】 , thus causes the greenhouse effect and acid rain, the earth's environment. Nuclear power faults: nuclear power under normal circumstances it is clean, but one thousand radiation leaks 【 Nuclear leak, also known as nuclear meltdown, is a kind of happened in nuclear reactor failure, serious sequelae. 】 , the same terrible consequences, such as Japan's fukushima nuclear leak happened recently and previous [in Russia The Russian federation ( 俄语：РоссийскаяФедерация） , hereinafter referred to as Russia, Russia, is made up of 22 autonomous republic, 46 states, nine frontier, four autonomous regions, 1 autonomous prefectures and three federal municipality directly under the central government of the federal republic of constitutional monarchy, land area of the world - eluosi】 As nuclear leak. Solar energy to meet the conditions of the new energy, forcing people to look for new energy, new energy sources to meet two conditions at the same time, the rich will not dried up; 2 it is safe, clean, not threat to humans and damage the environment. Now find the new energy mainly include solar energy and fuel cells. In addition, wind power is also supporting the new energy. Among them, the most ideal new energy is solar energy. As the traditional energy increasingly scarce, the application of solar energy will be more and more widely, especially in solar power field within the short several years has developed into a mature sunrise industry. In oil prices is unstoppable crazy speed fierce wind, solar firms are trying to cut costs, a main source to replace oil as the world's energy. It is predicted that by the end of this century, solar energy or will become the world's leading power sources, according to the current speed of soaring oil prices, the cost of solar power will soon with conventional electricity.
