Assertion: The renewable energy sources like solar, wind, hydro geothermal and biomass are considered as sustainable resources.
Reasoning: These energy sources are less equitably distributed in comparison to non renewable energy sources.

Assertion (A) is true but Reasoning (R) is not correct.

Fossil fuel sources, such as coal, petroleum, natural gas and nuclear energy use exhaustible raw materials. Sustainable energy resources are only the renewable energy sources like solar, wind, hydro geothermal and biomass. These energy sources are more equitably distributed and environment-friendly. The non-conventional energy sources will provide more sustained, eco-friendly cheaper energy after the initial cost is taken care of.
