Renewable energy has received a total investment of USD 70 billion (about Rs 5.2 lakh crore) in the last seven years across the country, according to Power Minister R K Singh. Given India's ambitious aim of 175 gigawatts (GW) of renewable energy by 2022, this is significant. Yesterday evening, Singh spoke at an event organised by the Ministry of New and Renewable Energy on 'Accelerating Citizen Centric Energy Transition' (MNRE). It was organised in partnership with India's Permanent Mission to the United Nations (PMI) and the Council on Energy, Environment, and Water (CEEW).
