In a world of higher electricity demand growth, clean electricity is stepping up to the challenge. Spearheaded by exponential solar expansion, clean power is set to grow faster than demand, marking the start of a permanent decline in fossil generation. 2024 both clarified and consolidated the shape of the global clean power transition. At first glance it might appear an unremarkable year, as global fossil generation increased for another year. However, the main driver of this increase was the change in temperature between 2024 and 2023. Stripping out these temperature effects, clean generation met 96% of the demand increase in 2024. Isolating the trend from the short-term fluctuations, it becomes clear that the world is very close to an era of falling fossil fuel generation. 2024 also cemented solar power as the engine of the global energy transition. Global solar generation increased by nearly a third, continuing its lead as the largest and fastest-growing source of new electricity. Its rise was on display everywhere in 2024, from world leaders like China, India, Brazil and the EU to new markets in Saudi Arabia and Pakistan. The startling expansion and cost reduction of battery storage offer another positive, enhancing the economics of solar power still further.
