Which indicator measures the share of energy use from renewable sources?

• A. Water Quality Index.
• B. Ecological footprint per capita.
• C. GDP growth rate.
• D. Renewable energy share of total energy consumption.

Answer: (D)

This question asks for the indicator that shows how much of a society’s energy use comes from renewable sources. The renewable energy share of total energy consumption directly expresses that idea by comparing the amount of energy from renewables to the total energy used, usually shown as a percentage. It’s a clear measure of how much of the energy mix is clean and renewable, which is why it’s the best choice for tracking progress toward a low-carbon energy system.

Water Quality Index measures the health of water bodies, ecological footprint per capita estimates overall resource use relative to available biocapacity, and GDP growth rate tracks economic output. While they provide important environmental or economic context, they don’t specifically quantify the portion of energy derived from renewable sources.
