What is the process of using nuclear fission to generate electricity called?
-
Hydropower
-
Thermal power
-
Nuclear power
-
Solar power
C
Correct answer
Explanation
Nuclear power is the process of using nuclear fission to generate electricity. It is a non-renewable energy source because it relies on the use of uranium, which is a finite resource.
