Conventional resources are those that have been in use for a long time and are typically non-renewable. These include fossil fuels like coal, natural gas, and mineral oil, which are widely used for energy production but are finite in nature and contribute to environmental pollution.
Non-conventional resources, on the other hand, are newer, renewable sources of energy that are considered more sustainable and environmentally friendly. These resources are renewable and can be replenished naturally, making them more suitable for long-term energy generation.
Among the given options:
- Coal (Option A), Natural gas (Option B), and Mineral oil (Option D) are all conventional, non-renewable fossil fuels.
- Wind energy (Option C), however, is a non-conventional resource. It is a renewable energy source that harnesses the power of wind to generate electricity. Wind energy is considered non-polluting and sustainable, making it a key component of the global transition to cleaner energy sources.
Therefore, the correct answer is Wind energy.
