Almost 90 per cent of global electricity generation in 2050 could come from renewable energy sources, with solar PV and wind together accounting for nearly 70 per cent, according to International Energy Agency’s new Net Zero 2050 roadmap.

The roadmap , published on 18 May, calls for scaling up solar and wind energy rapidly this decade to reach 390 GW of wind capacity added per year by 2030, of which new installed offshore wind capacity annually would be around 80 GW. By 2050, IEA sees 350 GW of wind energy added to the global energy mix each year, with 70 GW of that being installed offshore, in order for the world to achieve carbon neutrality.
