Another form of renewable energy is small wind turbines with a maximum power of 50 kW which are subsidized with particularly high sales prices under Law 3851/2010. These are small wind turbine plants that are characterized as non-obstructive or low-nuisance depending on the installed power and do not affect the surrounding area, and no particular infrastructure interventions are required as opposed to large wind projects or produce high noise emissions. A further advantage of small wind turbines is that depending on the technology of the wind turbine they operate at very low wind speeds and therefore do not have to be installed in isolated areas with very high wind potential.
Modern wind turbines are separated into horizontal wind turbines and vertical axis wind turbines. Currently, the horizontal axis wind turbines dominate the market. A small 50 kW wind turbine installed in a location with a mean wind speed of 7m / s produces an average of 150,000 kWh per year. Combined with favorable pricing, this makes it attractive to invest in small wind turbines.
