Wind energy

wind energy

Wind energy rely on renewable source of energy. It is power of moving air masses. Converted into electricity by wind turbines. Unfortunately, the energy generated by the winds is very unstable, variable. Typically, the variation in energy produced varies between 100 and 300 MW.

However, the advantage is that with 80% confidence we can predict energy from the wind even two days earlier.

There are three types of windmills on the market. The first oldest with a shoulder diameter of 50 meters and a height of 70 meters, produced in 1990, producing 0.8 GWh per year with 0.5 MW of turbine power. The second was created in 2005 with a height of 100 meters and a shoulder diameter of 90 meters. Produce 4.4 GWh per year with 2 MW turbine power. The third, the latest from 2015, with a height of 120 meters and a shoulder diameter of 120 meters. Produce 8.4 GWh per year with 3 MW turbine power.

Wind is generated by the heating of the earth. The heated air rises up and then the cool air is sucked in most often from the water side. This is how the wind is produced.
