Wind power

Slovakia is an inland country. The air circulation is not stable, during the year its direction and velocity changes. That’s why we have a lower wind-energy potential compared to other seaside countries in western and nothern Europe. The basic criterion for its estimation is the average wind velocity in certain altitudes. In the world, for below average are considered localities with average wind velocity less than 6 m/s. In Slovakia there are only two places with continuous wind velocity measurement where the average wind velocity exceeds 5 m/s and some others where the values are close to 5 m/s. From this we could conclude that wind energy in Slovakia has no future. However, it is not quite true:

-          wind in Slovakia blows mainly during the day (around noon). There is also high electricity consumption at this time.

-          wind energy doesn’t produce any emmisions

-          wind power plants represent decentralized energy production. That means there is no need to build large distribution networks.

-          operation costs of wind power plants are low (they can be controlled remotely)

-          air circulation in altitudes around 50 meters (axis of the wind power plant) is much more favorable, however, precise measurements have not been done in a long time

Drawbacks of wind energy (mostly in our conditions):

-          there are only a few localities suitable for the builging of a power plant and most of them are in protected areas

-          energy production depends on weather conditions (still wind, strong wind or frost mean plant shutdown)

2% of electricity produced in Europe comes from wind, however, in Denmark the wind power plants produce 20% of electricity.
