Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Solar energy is a clean and renewable energy source that is often used in green buildings to generate electricity or heat.

Multiple choice

Which of the following is an example of a renewable energy source that can help reduce air pollution?

  1. Solar energy

  2. Wind energy

  3. Hydropower

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Solar energy, wind energy, and hydropower are all examples of renewable energy sources that can help reduce air pollution. Solar energy uses the sun's energy to generate electricity. Wind energy uses the wind's energy to generate electricity. Hydropower uses the energy of flowing water to generate electricity. These renewable energy sources do not produce air pollution, unlike fossil fuels, which emit pollutants such as carbon dioxide, nitrogen oxides, and sulfur dioxide.
