Led by solar PV, renewables are poised to transform electricity systems across the globe this decade, with the world on course to add more than 5 500 GW by 2030, the International Energy Agency’s (IEA’s) ‘Renewables 2024’ report states. Such additions would increase global renewable electricity generation to over 17 000 TWh, which is roughly equal to the current combined electricity demand of China, the European Union, India and the US.
