The levelised costs
of electricity, which were generated by Bonus™ 300 kW/33 and
Bonus™ 1 MW/54, were promising at 0.019 US$/kWh and
0.012 US$/kWh, respectively. On the other hand, mean wind speed
of 5.65 m/s and the average wind power density of 217 W/m2 at
the height of 40 m were reported in Tunisia [9]. The vast variations
of the power density in Karnataka were found from 829.73 W/m2
in monsoon season to 186.15 W/m2 in winter season [20]. The
power density across Iceland varied between 300 and
1500 W/m2 in winter [11]. In Hong Kong, the capacity factor was
obtained with 0.35 or ever reached the maximum value of 0.50
in October [23]. The costs of electricity generation were estimated
to be 0.027 US$/kWh in Turkey and 0.041 US$/kWh in Jordan
