The advantages and disadvantages of each type of energy analysis

Now people put forward higher and higher requirements of energy, and search for new energy become the urgent task facing the current human. The existing energy mainly include hydropower, thermal power, nuclear power and new energy sources such as solar energy.

the disadvantage of hydropower, water and electricity to drown a large amount of land, 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 needs to the burning of coal, petroleum and other fossil fuels. 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 oxide, 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, the same terrible consequences.

solar energy to meet the conditions of the new energy, these are forcing people to find new sources of 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 to find new energy mainly include solar ( Solar street lamps) And fuel cells. In addition, wind power is also supporting the new energy. Among them, the most ideal new energy is solar energy.

along with the increasing shortage of traditional energy sources, 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.
