2.Hydroelectric power does not contribute to global warming

ABoth statements 1 and 2 are true ✓ Correct

BOnly statement 1 is true

COnly statement 2 is true

DNeither statement 1 nor statement 2 is true

Correct answer: (A) Both statements 1 and 2 are true

Explanation

Both statements about hydroelectric power are taken as true here.

Statement 1 is correct, as hydro is a renewable source generated using dams that harness flowing water.

Statement 2 is treated as correct, since hydro burns no fuel and so is regarded as not adding to global warming.

Water cycles naturally, so the resource renews continuously.

Generating electricity from falling water releases no carbon dioxide at the turbine.

Large reservoirs can still flood land and alter river ecology.
