The world is putting in wind generators and photo voltaic panels quicker than ever, however coal nonetheless generates extra electrical energy than another supply, and by an enormous margin.
The International Energy Agency (IEA) expects coal-fired energy vegetation to generate 10,974 terawatt-hours (TWh) in 2026, almost one-third of the 33,313 TWh of electrical energy produced worldwide. Pure fuel is a distant second at 6,976 TWh, adopted by hydropower at 4,536 TWh, photo voltaic at 3,289 TWh, wind at 2,898 TWh and nuclear at 2,871 TWh.
In different phrases, coal will generate almost as a lot electrical energy this 12 months as pure fuel and hydropower mixed. It is going to produce 77% extra energy than wind and photo voltaic mixed.
That creates a clumsy second for the worldwide vitality transition.
The IEA expects renewables collectively to overhaul coal in 2026 for the primary time. However that requires including hydropower, photo voltaic, wind, bioenergy, geothermal and different renewables collectively. No particular person supply is near coal.
And this 12 months, coal is getting one other sudden increase from the worldwide fuel market.
The Iran Warfare Driver
The IEA entered 2026 anticipating coal-fired energy technology to fall. Its Electricity Mid-Year Update 2025 forecast world coal technology would decline 1.3% this 12 months as renewable output surged and pure fuel displaced coal in some markets. However the ongoing U.S.-Iran conflict has prompted a change within the forecast.
The lack of LNG supplies by means of the Strait of Hormuz despatched fuel costs sharply greater in Europe and Asia, making coal significantly extra aggressive for energy mills capable of swap between fuels. The IEA now expects gas-fired technology to stay primarily flat in 2026, in contrast with the 1.3% improve it anticipated earlier than the conflict.

Coal technology is now anticipated to rise as a substitute.
Wind and photo voltaic can take an growing share of annual technology, however utilities nonetheless want energy when the wind slows, the solar goes down or demand abruptly jumps. Pure fuel has more and more crammed that function in markets attempting to cut back coal consumption. So, whenever you take that low-cost fuel away, coal abruptly turns into extra engaging.
That’s precisely what is occurring in elements of Asia and Europe this 12 months.
China And India Make The Numbers Work
Coal’s dominance is turning into extra concentrated in Asia, with China alone producing greater than half of the world’s coal-fired electrical energy. Coal provided round 55% of Chinese language electrical energy in 2025, even because the nation continued constructing extra wind and photo voltaic capability than the remainder of the world mixed, based on the IEA.
India is much more dependent, with coal supplying roughly 71% of Indian electricity final 12 months. Throughout Southeast Asia, the share was about 48%.
For China and India, it’s not so simple as changing one type of electrical energy technology with one other. The Asian push to construct huge new electrical energy provides from cleaner sources is not only in regards to the atmosphere. This can be a drive to fulfill rising demand.
China is concurrently the world’s largest coal shopper and its largest renewable-energy market. File renewable installations have helped drive coal’s share of Chinese language electrical energy decrease, however complete energy demand is so massive that the nation’s coal fleet continues to generate huge quantities of electrical energy.
Photo voltaic Is Rising Quick, However Coal Has A Huge Head Begin
The course of the worldwide energy market is evident: It’s constructing clear sources of vitality, however the street is beginning to look quite a bit longer.
Photo voltaic and wind are closing the hole rapidly, however they’re ranging from a lot additional behind. The IEA expects photo voltaic technology to leap round 30% this 12 months and wind by roughly 10%, serving to push complete renewable technology up greater than 8%.
Even after that progress, photo voltaic will generate 3,289 TWh in 2026 and wind 2,898 TWh, in contrast with 10,974 TWh from coal. Mixed, wind and photo voltaic will produce 6,187 TWh, which remains to be 44% much less electrical energy than coal.
Renewables solely transfer forward if we add hydropower, which can generate one other 4,536 TWh this 12 months. That’s the one perspective that permits us to say that renewables overtake coal this 12 months. The comparability’s downside is that coal is a fossil gasoline and we aren’t evaluating renewables and fossil fuels right here.
Coal Might Keep On High By 2030
The IEA expects coal to stay the world’s largest particular person supply of electrical energy by means of 2030. The Electrical energy 2026 outlook has world coal-fired technology declining by solely round 0.9% yearly between 2026 and 2030. Renewables will broaden far quicker and are anticipated to cowl just about all progress in world electrical energy demand over that interval.
Coal’s share of the worldwide energy combine will proceed falling, however the quantity of electrical energy generated from coal is anticipated to say no rather more slowly. The IEA forecasts coal-fired technology falling by a median of simply 0.9% yearly between 2026 and 2030.
The world at present will get almost 11,000 TWh of electrical energy yearly from coal. Changing that requires renewable technology to do two jobs directly: provide the extra electrical energy demanded and concurrently displace coal.
The world can set up extra renewable capability than ever earlier than whereas persevering with to burn monumental quantities of coal.
Changing coal turns into a lot tougher when the world additionally wants extra electrical energy. The IEA expects world energy demand to develop 3.6% this 12 months, and one other 3.8% in 2027, bringing consumption from 28,600 TWh in 2025 to 30,700 TWh in 2027. China’s electrical energy demand alone is forecast to develop 5.5% this 12 months, whereas India’s jumps 7%.
For renewables, it’s two steps ahead, three steps again. A lot of the brand new renewable technology being constructed has to fulfill new demand earlier than it might displace coal.
