Oil, gas and coal - it dries out the energy sources that will sooner or later run out. Therefore, more attention is paid to alternative energy sources (air mass, water, geothermal and so on. D.).
Alternative sources of energy: types, advantages and disadvantages
Energy - is the basis for modern life. In addition to traditional forms of energy, there are other types, they are quite promising and effective but little known. Alternative energy is a group of promising energy production methods. Attention alternative energy deserve more because of its profitability and the absence of harm to the environment.
Alternative energy source device or structure may serve, which allows you to extract electricity, etc. They can replace conventional oil, gas or energy derived from coal. In more detail with the topic can be found in the article "What is alternative energy?".
The most efficient alternative energy sources
Now effective following types of alternative energy sources:
- wind power;
Converting solar energy into electricity
Using thermodynamic photovoltaics or solar light is converted into electricity. Each of the methods has its own advantages and nuances. For example, when processing a photoelectric photoelectric converter is used. As a result, photons (particles of light) is converted into electricity.
The second least effective way - thermodynamic. Solar rays are converted first into heat by means of thermodynamic systems, and after electricity. The design of such devices consists of a generator, a turbine and a boiler that "accumulates" photons.
The use of wind energy to convert wind energy into electricity is called. The transformation is carried out in the wind power plants. The construction of such a plant is composed of the following parts:
- wind turbine;
- avtoupravlenie engine and generator;
- design for installation/maintenance.
This method of energy production cost is very cheap, but the power plant is rather weak, and this work is dependent on weather conditions.
Steam energy sources (earth internal heat) is converted into electricity. This is called geothermal energy. The ability to use the terrestrial heat appeared due to the fact that at a depth of 2 - 3 km temperature reaches the temperature 100 degrees. The energy produced from geothermal plants. There are three schemes of electricity production:
- In the direct method, steam is fed directly to the turbine through pipes, which are connected to a generator.
- Indirect scheme has a significant difference - a couple before hitting the turbine, he is cleared of harmful gases.
- The essence of the mixed technique that is fed to the crude steam turbines, and then the condensate is removed from the undissolved gas.
Geothermal energy is inexpensive. The cost of building the station is low, the processing system of steam is also relatively cheap.
If we talk about the shortcomings, is due to geothermal installation possible seismic activity and local subsidence. In addition, for the construction of the station specific geological conditions are needed.
The energy of tidal waves
Wave energy - is a method of extracting electricity by converting the wave / tidal energy. Power is much higher than the wind power installation. As with other types of alternative energy - a renewable source.
Power plants using tidal energy. To equip a tidal station (PES) requires the presence of the pool, river or bay. And the main drawback is that the plant can be built only by the sea / ocean / river.
The conversion of energy from biomass
Rotting garbage and organic waste (plant, dead organisms) leads the evolution of gas, which contains high levels of methane. This biogas can be used to produce energy and heat.
Thanks to the biomass energy sector, some companies, such as cowsheds or pigsties, the ability to provide heat and electricity.
After processing wastes are to be used as a fertilizer for the soil. The fuel can be used seaweed, cane or corn stalks, and others.
What are the advantages of solar energy?
Solar energy - a renewable resource. Actually as the flows of air and water masses. Photons falling into the atmosphere, but rather the number and density are dependent on weather conditions. Systems equipped with accumulating devices.
If volnoenergeticheskie station can be placed solely on the shore, and geothermal units operate mainly in the mountains, the solar power plants can be placed anywhere, it is only important to take into account the meteorological features.
Solar power does not necessarily occupies a large area, in the commercially available and more compact equipment that can provide the necessary amount of power house and other buildings.
Where can I buy solar power systems for home and produce?
Using solar energy is much cheaper. You only need to buy the equipment for converting solar energy electricity, for which it is not necessary to pay.
The company Ekotehnika can buy systems for homes and industrial buildings.
It can be networked or stand-alone solar power for home collectors. For business the most profitable and modern solution are photovoltaic modules and solar stations. Ekotehnika offers an affordable cost of solar cells and power.
Solar cells are able to store light energy, operate in all weather conditions (at dawn, in the rain, and so on. D.). They are used to implement many tasks. Depending on the needs, you can give preference to autonomous power or solar collectors.

For many owners of private houses have appreciated all the advantages of using household SPP, chief among them: the independence of the urban networks, the ability to sell excess energy on the "green tariff", environmentally friendly installation. The main drawback is currently a need for sufficient space stations and expensive mounting.
