Alternative energy – is an association of different ways to generate energy, which laid the basis for the use somovozobnovlyaemyh sources. It is not as developed as the traditional energy, however, the gradual exhaustion of mineral resources will lead to the inevitable transition of humanity to the use of alternative energy.
There is pleased kinds of alternative energy:
· solar energy;
· wind power;
· geothermal energy;
· storm energy;
· hydrogen energy;
· space energy.
Of all the types of alternative energy are the most popular solar, wind and hydropower.
Based solar energy incorporated the use of solar energy and convert it into electricity and heat. Conversion is done by all the possible solar installations. The advantage of this type of energy has a quiet, environmentally friendly, zero emissions into the environment. The disadvantage is that the production of electricity and heat is directly dependent on the intensity of sunlight.
Wind power through wind turbines and wind power, converts kinetic energy of wind into electricity. In windy areas the wind of our planet – is an inexhaustible source of energy and samovozobnovlyaemy. However, there are several drawbacks in the form of wind turbines noisy, bulky and low power unit installation.
Hydropower – the transformation of water into electric energy. Alternative hydropower can be divided into four types. This wave power, tidal power, small hydropower plants, waterfall power.
Geothermal energy uses the heat of the earth’s interior. It is divided into hydrothermal energy, which is necessary in principle the use of hot groundwater, and petrotermalnuyu energy, which uses deep heat of the planet. The advantages include the fact that this kind of energy does not depend on external factors, time of day and season of the year and fully inexhaustible. However, there are some negative aspects that hinder its development. These include the inability to discharge waste water into water bodies, because of its pollution. Just acute problem of profitability of geothermal energy.
Bioenergy allows different types of biofuels to produce energy and heat. Biofuels can be liquid, solid and gaseous. Bioenergy is currently under active development. Large industrial and agricultural enterprises to actively switch to biofuels, which allows them to obtain electricity and heat from organic waste. The main advantages is the utilization of organic waste, reducing environmental pollution.
Storm power also refers to energy sources that samovozobnovlyayutsya. Its essence lies in the capture and redirection of lightning into the grid. However, this is not a very reliable source of energy, as to know in advance where it will be impossible to storm.
Hydrogen power uses hydrogen as the most abundant element on Earth, for the storage and transportation of energy. Hydrogen energy by far the most developed in the automotive field.
Space power uses the sun’s energy. Then this energy is converted into electrical energy and power are located or in Earth orbit or on the moon.
As you can see in the future when the natural resources used in traditional energy runs out, we have something to make up for their lack.
