India’s population, currently 1.4bn, is growing and electricity use is soaring. India needs to add capacity equivalent to all of the EU’s output, over the next 20 years, according to the International Energy Agency. Today 70% of the country’s electricity comes from coal. The government has promised to increase renewable-energy capacity to 500 gigawatts by 2030, more than doubling the current output. But this would still account for just half of anticipated need. The creaking electricity grid needs an upgrade too. What is the Indian’s contribution in achieving net zero by 2050?
