The IEA’s latest World Energy Outlook 2024 shows solar overtaking nuclear, wind, hydro, gas and, finally, coal, to become the world’s single-largest source of electricity by 2033. This solar surge will help kickstart the “age of electricity”, the agency says, where rapidly expanding clean electricity and “inherently” greater efficiency will push fossil fuels into decline. As a result, the world’s energy-related carbon dioxide (CO2) emissions will reach a peak “imminently”, the IEA says, with its data indicating a turning point in 2025.
