The remaining carbon budget available to the world to limit global warming to 1.5 degrees celsius or to “well below 2°C” very small and is being rapidly depleted. The year 2021 has witnessed a flurry of pledges by countries to achieve net-zero emissions around the second half of this century. But the analysis shows the pledges of Annex-I parties to the United Nations Framework Convention on Climate Change to be highly inadequate to limit the temperature rise to below 1.5°C. In this context, this paper reviews India’s climate change mitigation efforts and policies over the last decade and assesses the recently declared net-zero emissions pledge against a range of illustrative emissions pathways and the implied cumulative emissions of these pathways. The ambition of India’s pledge is assessed, with a discussion of the challenges that lie ahead for India’s energy sector.

Solar-powered irrigation has expanded in India at an unprecedented pace—the number of solar irrigation pumps—from less than 4,000 in 2012 to more than 2,50,000 by 2019. It has been argued that besides giving farmers an additional and reliable source of income, grid-connected SIPs also incentivise efficient energy and water use—critical for sustaining groundwater irrigation. The Surya Raitha scheme was the country’s first, state-driven initiative for solarisation of agriculture feeders by replacing subsidy-guzzling, inefficient electric pumps with energy-efficient, net-metered SIPs. An early appraisal of Surya Raitha lauded the scheme as a smart initiative and argued that it could set an example for promoting solar power as a remunerative crop. However, the scheme was eventually executed as a single feeder pilot with some design changes in Nalahalli panchayat from 2015–18. The authors visited the pilot in 2017–18 and 2018–19 to assess if it had delivered the promises of Surya Raitha scheme. The results are a mixed bag and offer important lessons for implementation and scaling out of component C of the Government of India’s Pradhan Mantri Kisan Urja Suraksha evam Utthaan Mahabhiyan policy.

Demand for electricity in India is growing due to the increase in GDP and quality of life along with structural changes in the energy sector leading to the increase in the percentage share of electricity in the total final consumption of energy. Decarbonisation of the energy sector is a necessity, and it should be achieved without negatively affecting economic growth of the country. It can be best managed by having a diverse portfolio of technologies as diversity provides supply security, resilience, and hedging against price fluctuations. Therefore, all low-carbon technologies—hydro, nuclear, solar, and wind—should be exploited and provided with a level playing field.
