Environmental Indicators (El)

Although wind energy is legitimately held as a clean energy, electricity production based on wind energy still brings by itself certain environment impacts, chiefly expressed through environment impacts of grave energy – energy used for production of materials for wind turbines construction. As it is assumed that electricity used for materials production is generated in PC based power station, pollutant emissions generated by combustion of corresponding amount of coal are calculated, and devided by electricity production in lifetime. The results are given in Table 5.

3.1.2. Social Indicators (SI)

Job indicator is defined as number of paid hours devided by production of electricity in lifetime, determining engagement of employees for all options under consideration.
