Which one among the following is not a renewable energy source?

Renewable energy is defined as energy derived from natural sources that are replenished at a higher rate than they are consumed, such as sunlight, wind, and moving water [4]. Solar, wind, and hydroelectric power are consistently classified as renewable or sustainable resources because they are naturally replaced on a seasonal basis or are continuously available [4]. In contrast, nuclear energy is classified as a non-renewable energy source because it relies on exhaustible raw materials like uranium [3]. While nuclear power is a low-carbon energy source that contributes significantly to global electricity, it is distinct from renewables because its fuel source is finite and cannot be replenished once consumed [2]. Therefore, among the given options, nuclear energy is the only one that does not meet the criteria for a renewable energy source.
