electrical energy, which actively began to use, by historical standards, not so long ago, significantly changed the lives of all mankind.Currently, different types of power plants generate enormous amounts of energy.Of course, for a more accurate picture could find specific numerical values.But the qualitative analysis is not so important.It is important to note the fact that the electrical energy is used in all spheres of human life and activity.Modern man is hard to imagine how it was possible to do without electricity even some hundred years ago.
high demand for electric energy demands and the corresponding generation capacity.To generate electricity, as it is sometimes expressed by people in everyday life, used thermal, hydraulic, nuclear and other power plants.It is not difficult to see the specific form of generation is determined by the type of energy that is required to generate an electric current.In the hydroelectric energy of the incident from the height of the water flow is converted into an electrical current.Similarly, power to the gas is converted into electricity thermal energy combusted gas.
Everyone knows that in nature, the law of conservation of energy.All of these types of power plants are inherently convert one form of energy into another.In nuclear reactors comes a chain reaction collapse of certain elements to generate heat.This heat via specific mechanisms converted into electricity.Exactly the same principle applies thermal power plants.Only in this case, the heat source is an organic fuels - coal, oil, natural gas, peat, and other substances.The experience of recent decades has shown that this method of power generation is very cost causes significant damage to the environment.
The problem is that the reserves of fossil fuels on the planet are limited.They should spend sparingly.Advanced minds of mankind has long understood this and are actively seeking out of this situation.One option considered alternative power output, which work on different principles.In particular for energy uses sunlight and wind.The sun will shine and the wind always blow never get tired.As expressed by experts, it is inexhaustible or renewable energy sources which need to be used efficiently.
recently list, which includes the types of power plants, was short.There are three positions - thermal, hydraulic and nuclear power.At present, several well-known companies in the world conduct extensive research and development activities in the application of solar energy.As a result of their work appeared on the market converters of sunlight into electricity.It should be noted that their efficiency leaves much to be desired, but this problem sooner or later be resolved.Likewise, the situation with utilization of wind energy.Wind generators are becoming more common.
