HYDROPOWER

The main task of hydroelectric power plants is to convert the energy of water flow into electrical energy. For this, turbines are used, which are connected to generators. The leaders in hydropower generation are Norway, Iceland, Canada and China. Hydropower plants are built on rivers, constructing dams and reservoirs.

In Ukraine, hydroelectric power plants are divided into: small (MHP) with a capacity of 1 to 30 MW; mini-hydropower plants - from 100 to 1000 kW; micro-hydropower plants - no more than 100 kW, as well as medium - from 30 to 1000 MW and large - more than 1000 MW.

By type, hydroelectric power plants are divided into: channel, dam, diversion, pumped storage and tidal.

The Svitovyr company offers the full range of construction, modernization and maintenance works.

SOLAR ENERGY

According to astronomers, the Sun will shine for at least another 5 billion years. Thus, the development of solar energy has considerable prospects for existence. Such energy can be converted into electricity in two ways: thermodynamic and photovoltaic. The thermodynamic method consists in the fact that the heat from fuel combustion in thermal plants is replaced by a stream of concentrated solar radiation. The photovoltaic method is the conversion of solar radiation into electrical energy.

The southern regions are best suited for installing solar power plants in Ukraine. The average annual insolation level ranges from 2.92 to 3.58 kW/m²/day. The positive aspects of solar power plants are that they can be installed almost anywhere (ground, roof, wall). The rapid development of solar energy in Ukraine began with the adoption of the green energy development program in 2008. Every year, solar panels become more efficient, allowing them to convert solar radiation into electricity with less loss.

WIND ENERGY

Scientific studies show that the Earth's wind energy potential is 1200 TW. This figure is quite high, but the possibilities of using this type of energy are different in different regions of the Earth. Wind turbines are used to convert wind flow into energy. The principle of operation of which is as follows: under the pressure of the wind, a wind wheel with blades rotates, which transmits torque through the transmission system of the generator shaft, which produces electricity. 
There are two fundamentally different designs of wind power plants: with a horizontal and vertical axis of rotation. The power of the wind flow is proportional to the area of ​​its cross-section and has a cubic dependence on the wind speed, that is, its power grows even faster than the wind speed. Wind power plants are recommended to be installed in areas with strong and constant winds, namely: coastal strips and mountain tops.
