Renewables in electricity must increase 55-fold for India to achieve net-zero emissions by 2050, according to a report by Council on Energy, Environment and Water (CEEW).
India will need to generate at least 83 per cent of its electricity from (non-hydro power) renewable energy sources by 2050 to achieve net-zero greenhouse gas emissions by mid-century, according to the study.
This would mean a massive 55-fold increase in the use of non-hydro renewables in electricity generation within the coming three decades, from only 160 Terawatt-hour (TWh) (10 per cent) in 2019, CEEW said in a statement.
Further, to achieve net-zero by 2050 the share of electricity in India's industrial energy use must rise three-fold, from 20.3 per cent in 2018 to 70 per cent in 2050, the study - Peaking and Net-Zero for India's Energy Sector CO2 Emissions: An Analytical Exposition - revealed.
The share of electric vehicles in passenger car sales will also have to rise to 76 per cent by 2050 from just 0.1 per cent in 2019, it added.
These estimates are based on CEEW's best understanding of progress on mitigation technologies.
To meet net-zero, India will need to either eliminate greenhouse gas (GHG) emissions or balance these by sequestering GHG emissions.
The study is the first exercise to outline multiple pathways for India to attain net-zero emissions, rather than fixating on a single scenario or a single year.
