Even if water is not present, we can use the warm ground at depths of 4 to 300 feet for heating and cooling residential or commercial buildings.
What is wind energy?
The use of wind turbines to generate electricity.
Is geothermal energy a renewable resource?
Yes, the heat coming from the core of the earth cannot be depleted by human activities.
What is the main factor that decides how much energy a wind turbine may supply?
Height
What are the drawbacks of geothermal energy?
There are no drawbacks, only advantages to the use of geothermal energy for electricity production and direct use (heating, cooling).
What is the life span of a wind turbine?
18-20 years.
Where is geothermal energy found?
Geothermal energy is generated in the earth's core, about 4,000 miles below the surface
What type of energy do wind turbines use to create electricity?
