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 because they are formed from the remains of ancient plants and animals over millions of years and cannot be replenished at a rate comparable to their consumption.
What is the main component of a wind turbine?
-
Blades
-
Generator
-
Tower
-
All of the above
D
Correct answer
Explanation
Wind turbines consist of blades that capture the wind's kinetic energy, a generator that converts this energy into electrical energy, and a tower that supports the entire structure.
Which of the following is a type of renewable energy source that utilizes heat from the Earth's interior?
-
