The use of coal, oil and natural gas is expected to decline by 2023, according to a report published by energy think tank Ember. That would mark the first year that fossil fuels will be used to generate electricity outside of a global recession or pandemic. The findings suggest the world has reached "the beginning of the end of the fossil age," lead author Malgorzata Wiatros-Motyka said in a statement. Wind and solar will account for 12% of global energy generation in 2022, with solar the fastest-growing source of electricity, up 24% from the previous year. Ember predicts that by 2023, clean energy will be able to meet the growth in total electricity demand. Coal remains the world's largest single source of electricity, accounting for 36% of global electricity production in 2022.
