NCERT (2026-27): “Non-Conventional Energy Sources … 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, hydrogeothermal and biomass. These energy sources are more equitably distributed and environment-friendly.” |
