Solar energy is continuously supplied by the Sun and is not depleted by human use. As long as the Sun shines,the resource is available,which makes it renewable in nature. The stem clearly refers to using solar energy for electricity,so renewable is the correct classification. Therefore Option D is appropriate.

Option A:
Non renewable resources are finite and not replenished on human timescales,unlike solar energy.

Option B:
Fossil resources come from ancient organic matter; solar energy is sunlight,not fossil fuel.

Option C:
Nuclear energy depends on fission fuels like uranium,not solar radiation captured by PV panels.

Option D:
Renewable resources such as solar are naturally replenished and are central to clean energy transitions,matching the stem.

Wind energy is continuously replenished by atmospheric processes driven by solar heating and Earth’s rotation. Using wind to generate electricity does not deplete the underlying resource. This aligns with the definition of a renewable resource. Therefore renewable is the appropriate label in the question.

Option A:
Renewable resources can be used repeatedly without being exhausted if managed properly. Wind turbines harness the kinetic energy of moving air without permanently reducing future wind. This characteristic makes wind energy a classic renewable resource.

Option B:
Non renewable resources such as coal,oil and natural gas are finite and form over geological timescales. Once burned,they cannot be quickly replaced. Wind does not share these constraints,so non renewable is an incorrect classification here.

Option C:
Fossil based resources originate from ancient organic matter converted into fuels like coal and petroleum. Wind has no such origin and is not derived from fossil material. Thus fossil based is not a valid description for wind energy.

Option D:
Nuclear based energy relies on fission or fusion of atomic nuclei,commonly using uranium. Wind energy generation does not involve nuclear reactions,so categorising it as nuclear based would be wrong.
