With development of modern technologies the quantity of alternative energy sources only increases. Work with such power sources as means: energy of the sun, wind, biofuel and internal heat of the earth.
There are various alternative energy sources which allow to save considerably electricity and to cut its consumption. Alternative power sources it is accepted to call the equipment intended for catching and use of inexhaustible energy of the environment.
One of the major alternative energy sources it is considered to be energy of the sun. Solar energy represents the specific direction of power based on use of sunlight for obtaining energy. Solar power stations make energy without emissions of harmful waste.
As for wind power, it specializes in transformation of energy of an air flow to other kind of energy. Especially actively wind power is applied in the national economy. Transformation of wind power is carried out by means of such installations as wind generators, wind mills and others. Wind power can be referred to renewables. Now this branch of power very dynamically develops. Modern wind generators are usually created from fiber glass and a coal plastic. Power of the existing wind generators is extremely high.
Also electric energy can be made due to energy which contains in the depths of the earth. Actually the geothermal power is also based on it. Access to underground waters vozmozhny only by well-drilling. Also high-temperature breeds are considered as very demanded. Energy from such breeds is usually received by means of downloading and selection from them of superheated water. By the way application a geoterm as a power source is considered especially perspective. Economic use of geothermal sources is widespread in many countries of the world. The most important source of alternative energy can be considered biofuel. This fuel is received from animal or vegetable raw materials and also industrial wastes. There is a solid, gaseous and liquid biofuel. Liquid it is often applied to internal combustion engines. Solid biofuel can be considered firewood, straw, briquettes. And gaseous biofuel is a biogas and hydrogen. Now technologies of biofuel continue to be improved. The market of biofuel can be considered almost boundless.
