Which strategy is most appropriate for delivering electricity in remote, off-grid Indian hilly regions while remaining environment-friendly?
ASetting up large-scale coal-fired thermal stations near the village cluster
BMini-hydel plants tapping perennial streams to power small turbines locally
CExtending the central transmission grid using long-distance high-voltage lines
DInstalling diesel generator sets at every village panchayat
Answer & Solution
Correct answer: B. Mini-hydel plants tapping perennial streams to power small turbines locally
Mini-hydel plants use small perennial streams in mountainous regions, generate enough power locally to meet demand, avoid transmission loss, and do not change land-use patterns. Long grid extension and diesel sets carry far higher environmental and financial costs.
