In 2024, renewables and nuclear power accounted for 40.9% of world energy era, marking the primary time this determine has surpassed 40% for the reason that Nineteen Forties, in keeping with a current report by the worldwide power suppose tank Ember.
Renewable power sources added a report 858 TWh in 2024, which is 49% greater than the earlier peak in 2022. For the third consecutive 12 months, photo voltaic power was the main contributor, including 474 TWh and reaching a 6.9% share of world electrical energy era. Moreover, photo voltaic has constantly been the fastest-growing energy supply, experiencing a 29% development for the twentieth 12 months working.
In whole, photo voltaic power manufacturing has doubled over the previous three years, contributing over 2,000 TWh of electrical energy in 2024. Wind power additionally expanded its share to eight.1% of the worldwide electrical energy combine, whereas hydropower, the most important renewable power supply, maintained a gradual 14%.
Phil MacDonald, managing director of Ember, emphasised that “solar energy has turn into the engine of the worldwide power transition.” He famous that when paired with battery storage, photo voltaic is poised to be an unstoppable drive, essential for assembly the rising world electrical energy demand.
Ember’s sixth annual World Electrical energy Evaluate presents an in depth overview of the state of the world’s energy methods in 2024, primarily based on country-level knowledge. This report was launched alongside the primary open dataset on electrical energy era for 2024, which covers 88 international locations that collectively account for 93% of world electrical energy consumption, together with historic knowledge for 215 international locations.
Relating to the components driving elevated energy demand, the report highlights a 1.4% rise in fossil gasoline use in 2024, pushed by surging electrical energy demand, which subsequently pushed emissions from the facility sector up by 1.6% to a report excessive. The evaluation attributes this enhance largely to heatwaves, which accounted for practically a fifth of the rise in electrical energy demand attributable to enhanced cooling wants. With out these temperature-related results, the expansion in fossil gasoline era would have been minimal, with clear electrical energy sources assembly 96% of the demand enhance not pushed by warmth.
MacDonald famous that whereas the warmth from rising temperatures contributed to the rise in fossil gasoline era in 2024, the same pattern is unlikely in 2025. Rising applied sciences, together with AI, knowledge facilities, electrical autos (EVs), and warmth pumps, are additionally important contributors to rising world electrical energy demand, with these sectors accounting for a 0.7% enhance in 2024—double the contribution from 5 years prior.
The report means that the expansion charge of unpolluted power era is anticipated to outstrip the growing demand within the coming years, signaling a probable decline in fossil gasoline era. The anticipated clear power development would comfortably accommodate an annual demand enhance of 4.1% by means of 2030, which exceeds projections for demand development.
MacDonald remarked, “The world is watching how applied sciences like AI and EVs drive electrical energy demand,” asserting that the expansion of photo voltaic and wind power is sufficiently sturdy to fulfill this demand. He warned that expectations of continued development in fossil gasoline era would possibly result in disappointment.
China and India are pivotal on this transition to wash power, with over half of the rise in photo voltaic era globally coming from China in 2024. China’s clear power development met 81% of its demand enhance, whereas India’s photo voltaic capability additions doubled in comparison with 2023. Specialists agree that their growing reliance on renewables will considerably affect the worldwide power panorama and expedite the decline of fossil fuels.
Professor Xunpeng Shi, president of the Worldwide Society for Power Transition Research (ISETS), identified that the power transition is being predominantly formed in Asia, with China and India driving this motion.
For these taken with enhancing house resilience to energy outages, exploring photo voltaic options alongside battery storage could also be helpful. To seek out dependable photo voltaic installers in your area at aggressive costs, think about using EnergySage, which connects customers with pre-vetted photo voltaic suppliers, making certain high quality options whereas saving on prices. The platform facilitates simple comparisons of personalised photo voltaic quotes and presents steerage from unbiased power advisers all through the method.
