Non-conventional sources of energy, such as solar, wind, and biomass, are significant for the following reasons:
• Renewable and Sustainable: Unlike coal and petroleum, non-conventional energy sources are renewable and can be used indefinitely. For example, solar power in Rajasthan.
• Environmentally Friendly: They produce minimal pollution and help combat climate change. Wind farms in Tamil Nadu generate clean energy.
• Energy Security: Reduces dependency on imported fossil fuels, strengthening energy security. For instance, India’s focus on solar energy reduces oil imports.
• Cost-Effective: Technological advancements have made renewable energy cost-efficient in the long run.
