Context: In this episode of the Perspective Prog. based on Investment in Green Technology. India has made significant commitments at COP26 towards climate action. 

• These include fulfilling 50% of its energy requirement through renewable energy and bringing its non-fossil fuel energy capacity to 500 GW by 2030. 
• All this will require huge investment in green technologies and big corporates are gearing up for this task. 
• Solar and wind energy prices have fallen over 90% since 2000, incentivised by only modest subsidies. However, solar and wind energy are intermittent and cheap storage is needed for them to ensure power 24/7. 
• New batteries and renewables are all set to power the world in a few decades based on commercial profitability. 
• India’s 2030 vision of e-mobility includes 70 per cent of all commercial cars, 30 per cent of private cars, 40 per cent of buses, 80 per cent of two-wheelers and three-wheeler sales to be electric by 2030. 
• This translates into more than 100 million Electric Vehicles and would require approximately 12.5 lakh crore rupees investment. 
• Hydrogen is also emerging as an important source of energy since it has zero carbon content and is a non-polluting source of energy in contrast to hydrocarbons that have net carbon content in the range of 75–85 per cent. 
• By moving to a hydrogen economy, India can not only reduce imports of oil, coal, and natural gas, but will also be able to export hydrogen to other countries in Europe and Asia.
