Renewable energy is acknowledged as a measure for both mitigation and adaptation. At least 34% of the 190 countries that had submitted NDCs by the end of 2020 mentioned renewable energy in their adaptation component.30 India, too, has focused on renewable energy to aid its adaptation efforts. Though, in 2022, India fell short of its renewable target of 175 gigawatt (GW) comprising 100 GW from solar, 60 GW from wind, 5 GW from 'small' hydro and the remaining 10 GW from bio-power – developing 120 GW of renewable energy capacity by the end of the year31 the country has seen considerable growth in the sector. It has set an ambitious goal of 500 GW of non-fossil fuel capacity by 2030.32 Solar and wind are expected to draw in significant investment this decade due to their potential to offer sustainable, commercial returns to businesses.33 India’s solar and wind power base is the fourth largest in the world.34 Hybrid projects have piqued interest as well. For example, a large corporation recently commissioned its third wind-solar hybrid power plant in Rajasthan.
Solar photovoltaics (PV) is among the fastest growing sub-sectors. While an estimated 12.7 million people were either directly or indirectly employed in the renewable energy sector globally in 2021, a third of these jobs were in solar PV.35 India is also making strides in solar PV, increasing its capacity to 10.3 GW in 2021, up from 4.2 GW installed in 2020. Supportive regulatory frameworks, such as the government’s production-linked incentive (PLI) scheme, are giving a boost to domestic manufacturing. India is expected to add an estimated 29 GW of cell capacity and 33 GW of module capacity by 2025.36
Despite these advantages, the overall share of renewable energy in the primary energy mix needs to increase to 75% for the world to meet the 1.5°C climate goal of the Paris Agreement. This requires an annual investment of over USD 4.4 trillion.37 More investments are being made in energy-related climate tech globally. The shift is especially remarkable in neighbouring China, where startup investment in energy-related tech increased to 22.2% in 2023 from just under 2% in 2018.38
Technological innovations can extend the benefits of renewable energy-based solutions to non-energy services. For instance, distributed renewable energy solutions – technologies that don’t rely on centralised energy generation – are increasingly being deployed in remote regions to provide access to water.39 Decentralised solar- or wind-powered water purification systems can be a cost-effective solution in developing countries.40
Furthermore, vapour (or fog) harvesting is an emerging technology that collects water in the ambient air. Desert safaris in Dubai are using hydro panels that turn vapour in the atmosphere into drinking water using solar PV and solar thermal technologies.41
