Energy Resources and Storage Questions

Multiple choice

Which of the following is NOT a renewable resource?

  1. Solar energy

  2. Wind energy

  3. Fossil fuels

  4. Hydropower
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Fossil fuels, such as coal, oil, and natural gas, are non-renewable resources because they are formed from the remains of ancient plants and animals and take millions of years to replenish.

Multiple choice

Which of the following is an example of a renewable energy source?

  1. Solar energy

  2. Wind energy

  3. Hydropower

  4. Nuclear energy
Reveal answer Fill a bubble to check yourself
Correct answer
Explanation

Solar energy, wind energy, hydropower, and nuclear energy are all considered renewable energy sources because they can be replenished naturally.

Multiple choice
