Question

which energy source contributes least to global warming?

a. geothermal

b. oil

c. petroleum

d. coal

Explanation:

Geothermal energy is a renewable energy source that harnesses heat from the Earth's interior. It produces very little greenhouse gas emissions during operation. Oil, petroleum (which is similar to oil), and coal are fossil fuels. When burned, they release large amounts of carbon dioxide and other greenhouse gases, which significantly contribute to global warming. So among the options, geothermal contributes the least to global warming.

Answer:

A. Geothermal
