In 2023, solar and wind power continued to grow, with solar producing a record 5.5% of global electricity and wind reaching 7.8%. China was the primary driver for both, accounting for 51% of solar growth and 60% of wind additions. Conversely, coal generation reached a record high of 10,434 TWh (35% of the global mix), largely due to droughts in China reducing hydropower output, which fell by a record 88 TWh. Fossil gas remained the second-largest source at 23%, with growth driven by the US. Nuclear generation saw a slight rebound to 9.1% of the mix, while bioenergy reached a record 697 TWh (2.4%). The report notes that while solar and wind are on a positive trajectory, coal and gas must decline sharply, and nuclear and hydro must accelerate growth to meet IEA Net Zero Emissions targets by 2030.
