Question

The citizens of a town are aware of climate change, and they want to make changes to control it. One change they consider is replacing the nearby thermal power plant with a hydroelectric plant. If they want to make sure this change will help to slow climate change, which question should they ask?

Answer 1

They should mostly ask if a hydroelectric power plant emit less CO2 than a thermal power plant. In global warming, CO2 is one of the elements that causes global warming.

Answer 2

Answer:

They should ask the following question "Does the hydroelectric power plant emit less CO2 than a thermal power plant?"

Explanation:

Carbon dioxide (CO2) is responsible for more than 80% of the pollution generated by global warming. So if the population is worried about climate change and wants to make changes to control it, they should worry that those changes will emit less CO2 into the atmosphere, otherwise the change will not be beneficial.
