36
The ______ energy from the wind is captured by a _____________.
37
What are… Mechanical and wind turbine?
38
This energy source can only be used to create electricity on a plate boundary or hotspot
39
What is… geothermal?
40
Creating ethanol from sugar cane is an example of using this source of energy.
41
What is… biomass?
42
In a hydropower plant the kinetic energy of the falling water is used to do this.
43
What is… Turn a turbine?
44
When using uranium or coal in a power plant heat is produced. These are the additional steps needed to make electricity.
45
What are… Heat water to steam, steam turns a turbine, turbine spins a generator which produces electricity
46
This occurs when energy goes from one object to anther object.
47
What is… Energy transfer ?
48
This occurs when energy goes from one form to another.
