I gave my students this multiple choice question: Burning coal and natural gas are ways to produce electricity. Both coal and natural gas are nonrenewable resources. Which is an example of producing electricity using a renewable source of energy?

Only one answer is correct among these 4 choices:
- using food pieces to make compost
- gliding a boat through the water using sails
- putting an energy-saving lightbulb in a lamp
- heating a home with energy collected by solar panels

Could you tell me which one is correct?

heating a home with energy collected by solar panels
