Question

“The generation of energy through non-conventional sources is the need of the hour for sustainable development.” Explain the statement with examples.

Answer 1

1. Generating energy from non-conventional sources is essential for sustainable development because it reduces reliance on fossil fuels, limits environmental harm, and encourages cleaner energy options. Sources such as nuclear, solar, wind, tidal, geothermal, and bio-energy provide renewable and environmentally friendly alternatives.
2. Nuclear energy, produced from uranium and thorium, is emerging as an important source of power. India has large uranium reserves in regions like Rajasthan, Maharashtra, and Chhattisgarh, while thorium is found along the coastal areas of Kerala and Tamil Nadu. Nuclear power stations such as Tarapur and Kalpakkam help meet energy demands without releasing harmful pollutants.
3. Solar energy, captured through photovoltaic cells and solar thermal technology, is another significant energy source. It is economical, eco-friendly, and becoming more efficient. States like Gujarat and Rajasthan have high solar potential. Solar energy is used in devices such as heaters and cookers, offering a sustainable substitute for fossil fuels.
4. Wind energy is also a clean source of power, where wind turbines convert kinetic energy into electricity. States such as Rajasthan, Gujarat, Maharashtra, and Karnataka benefit from suitable wind conditions, enabling them to produce renewable energy.
5. Other non-conventional sources, including tidal, geothermal, and bio-energy, further expand energy choices. These sources contribute to sustainable development by lowering pollution levels and conserving natural resources.
