Based in 2005 as an Ohio-based environmental newspaper, EcoWatch is a digital platform devoted to publishing high quality, science-based content material on environmental points, causes, and options.
A brand new report has discovered that 40.9% of worldwide electrical energy manufacturing final yr got here from “clear,” low-carbon power sources akin to photo voltaic and wind energy. This quantity is up from the 39.4% share clear power had of the overall electrical energy technology combine in 2023.
In line with the sixth annual International Electrical energy Overview from Ember, whole international electrical energy manufacturing was comprised of seven% photo voltaic, 8% wind, 14% hydropower, 9% nuclear power and three% different renewable sources. Main strides in photo voltaic and wind energies specifically helped electrical energy technology from low-carbon sources surpass 40%.
Photo voltaic power has doubled to achieve greater than 2000 terawatt hours (TWh) over the previous three years and for 2024, this power supply was the largest supply of latest electrical energy technology for the third consecutive yr, Ember famous. Photo voltaic has additionally been the quickest rising supply of electrical energy technology for the twentieth consecutive yr as of 2024, the report discovered.
“Solar energy has turn out to be the engine of the worldwide power transition,” Phil MacDonald, managing director at Ember, mentioned in a press release. “Paired with battery storage, photo voltaic is ready to be an unstoppable power. Because the fastest-growing and largest supply of latest electrical energy, it’s essential in assembly the world’s ever-increasing demand for electrical energy.”
Solar energy manufacturing elevated notably in China, the place 53% of the rise in photo voltaic for 2024 befell. Final yr, China set a file for installations of latest photo voltaic and wind energy for the second yr in a row.
Though the rising reliance on clear power sources was a spotlight of Ember’s report, the power think-tank identified that heatwaves in 2024 additionally led to an elevated demand for electrical energy, a few of which was met utilizing greater fossil gas output.
International electrical energy demand elevated 4% in 2024 in comparison with the two.6% improve in demand in 2023, and electrical energy technology from fossil fuels elevated 1.4% final yr. Additional, carbon emissions from international power elevated as properly, reaching 14.6 billion metric tons — a file excessive.
In line with Ember, the upper temperatures of 2024, which has been deemed the most popular yr on file, had been the principle trigger of upper fossil gas electrical energy technology. With out the heatwaves, fossil gas energy technology would have elevated about 0.2% final yr. Nevertheless, the report authors don’t anticipate as excessive of a rise for this yr.
“Amid the noise, it’s important to deal with the actual sign,” MacDonald mentioned. “Hotter climate drove the fossil technology improve in 2024, however we’re not possible to see an identical bounce in 2025.”
Different elements, together with powering synthetic intelligence, information facilities and EVs, are additionally contributing to rising demand, Ember discovered. The report confirmed that energy demand for these applied sciences was linked to a 0.7% improve in electrical energy demand for 2024.
Nevertheless, the authors are optimistic that rising demand for know-how might be met with a rise in clear energy sources over fossil fuels sooner or later.
“The world is watching how applied sciences like AI and EVs will drive electrical energy demand,” MacDonald mentioned. “It’s clear that booming photo voltaic and wind are comfortably set to ship, and people anticipating fossil gas technology to maintain rising might be dissatisfied.”
