Why is geothermal energy better than wind energy for power generation?


Wind is unpredictable. Strong, steady wind with uniform velocity cannot be guaranteed at a place. The speed of wind varies at a place with time and season. Therefore, wind mills cannot ensure steady generation of power for 24 hoursa day throughout a year. Moreover, the wind mills and the turbines remain unoperational when wind blows at a slower speed which adds up to the operational cost. On the other hand, geothermal power plants can operate round the clock. Though the initial cost of setting up of a geothermal plant is high like a wind farm, but the operating cost of the former is less.
