Renewable energy has emerged as an important component of Karnataka's energy system, contributing to energy security, environmental sustainability and regional economic development. Karnataka possesses considerable potential for solar, wind, hydropower, biomass and other renewable energy resources because of its varied physical geography, high solar radiation, extensive plateau regions, favourable wind corridors, and agricultural base and river systems. The present study examines the spatial distribution and growth of renewable energy sources in Karnataka from a geographical perspective. Particular attention is given to solar, wind, small hydro, biomass and co-generation, together with the regional factors influencing their distribution. As of 31 March 2025, Karnataka had about 23.92 GW of renewable-energy installed capacity and ranked fourth in India in renewable-energy installed capacity. Solar constituted 47.85 per cent of the state's renewable-energy capacity, while wind accounted for 36.34 per cent. Renewable energy contributed 48.10 per cent of Karnataka's total electricity generation during 2024–25.
