The long read: More or less

How much granularity in monitoring and optimization is enough?

India’s renewable energy subsidies fell 35% in three years

The subsidies to renewable energy went from a high of Rs 15,313 crore in FY2017 to Rs 9,930 crore in FY2019. At the same time, government subsidies for oil and gas went up from Rs 40,762 crore in FY2017 to Rs 67,679 crore in FY2019. Unprecedented resource crunch post-Covid-19, however, presents a good opportunity for the government to rein in specific fossil fuel subsidies while creating more fiscal room for promoting renewables and other welfare schemes—according to a new report by the International Institute for Sustainable Development (IISD) and the Council on Energy, Environment and Water (CEEW).
