Which of the following is NOT a renewable energy source?
-
Solar Energy
-
Wind Energy
-
Hydropower
-
Fossil Fuels
D
Correct answer
Explanation
Fossil fuels, such as coal, oil, and natural gas, are non-renewable energy sources formed from the remains of ancient plants and animals. Renewable energy sources, on the other hand, are replenished naturally and can be used indefinitely.
The photovoltaic effect is the basis for which renewable energy technology?
-
Solar Photovoltaics
-
Wind Turbines
-
Hydroelectric Dams
-

A
Correct answer
Explanation
The photovoltaic effect is the process by which certain materials generate an electrical current when exposed to light. This principle is utilized in solar photovoltaic (PV) systems to convert sunlight directly into electricity.
Which type of renewable energy technology harnesses the kinetic energy of moving air?
-
Solar Thermal
-
Wind Turbines
-
Biomass Energy
-
Tidal Energy
B
Correct answer
Explanation
Wind turbines convert the kinetic energy of moving air into mechanical energy, which is then used to generate electricity. Wind energy is a clean and sustainable source of renewable energy.
What is the primary energy source for hydroelectric power plants?
-
Sunlight
-
Wind
-
Moving Water
-
Geothermal Heat
C
Correct answer

Which renewable energy technology converts organic matter into usable energy?
-
Solar Thermal
-
Wind Turbines
-
Biomass Energy
-
Tidal Energy
C
Correct answer
Explanation
Biomass energy involves the conversion of organic matter, such as plant materials, animal waste, and wood, into usable energy. This can be done through combustion, anaerobic digestion, or other processes.
What is the primary energy source for geothermal power plants?
-
Sunlight
-
Wind
-
Moving Water
-
Heat from the Earth's Core
D
Correct answer
Explanation
