Wind and solar power generated 22% of the world's electricity in April 2026, surpassing gas-fired generation for the first time on a monthly basis, climate think tank Ember reported. The milestone, driven by a global energy crunch that made gas unaffordable, marks a shift in how nations keep lights on during supply crises. "The current energy crisis has further strengthened the economic case for renewables compared to imported gas," said Ember analyst Kostantsa Rangelova.
The numbers tell a stark story. Gas generation fell to 20% of the global total, down from its typical share, as the Strait of Hormuz blockade choked off roughly one-fifth of the world's liquefied natural gas production capacity. Prices spiked.
Utilities scrambled. Solar panels and wind turbines, with zero fuel costs, suddenly became the cheapest option for many grid operators. Reuters first reported the Ember data, which captures a month when the energy world turned upside down.
The 30-nation military coalition led by the UK and France was still working to reopen the Strait. Tankers carrying millions of barrels sat idle. In that vacuum, renewable energy did something it had never done before: it beat gas on a global scale. "The current energy crisis has further strengthened the economic case for renewables compared to imported gas, while also adding greater political urgency to accelerate deployment," Rangelova told Reuters.
But the picture is more complicated than a clean-energy victory lap. Across Asia, the same price shock that made solar attractive also revived coal. The solid fuel remains the most affordable baseload generation option in much of the developing world.
As gas prices soared, countries from India to Vietnam fired up coal plants that had been running below capacity. The parallel growth in wind and solar on one hand, and coal on the other, suggests affordability remains the top priority for most governments. This dual trend undermines a simple narrative.
It is not a transition so much as a triage. When gas is scarce and expensive, grids reach for whatever is cheapest and fastest. Sometimes that is a solar farm.
Sometimes it is a coal plant. The policy says one thing. The reality says another.
Bob McNally, founder of Rapidan Energy Group and a former White House energy adviser, warned against assuming the shift is permanent. "Some people are saying this oil-price spike will do what the Paris Agreement and EV mandates haven't," McNally told Fortune, "which is to convince everybody to destroy demand for gasoline. But busts follow booms."
McNally's point cuts to the heart of the energy debate. When oil prices drop, the urgency to electrify fades. "When oil prices drop, I think demand for EVs will wane," he said. "You're on this roller coaster of oil prices."
The Strait of Hormuz crisis has scrambled every energy forecast. The first LNG tanker broke the blockade only recently, OilPrice reported. Three supertankers carrying 6 million barrels exited the strait in a single convoy.
But the system has already broken, as one OilPrice analysis noted. Venezuela oil exports hit a seven-year high as buyers scrambled for alternatives. US crude inventories came crashing down.
Goldman Sachs sounded a fresh alarm on global oil stockpiles, warning that the cushion between supply and demand is dangerously thin. Traders expect oil prices to remain above $81 for the next 12 months, according to a separate OilPrice survey. That price floor keeps pressure on gas markets and, by extension, on electricity grids everywhere.
What this actually means for your family. Higher electricity bills, for one. When gas prices spike, utilities pass the cost to consumers.
The April milestone for renewables is real, but it did not happen because the world built enough wind turbines and solar panels to meet demand. It happened because gas became too expensive to burn. That is a crisis-driven milestone, not a planned transition.
The economic toll extends beyond electricity bills. A Chevron executive told OilPrice that Venezuelan crude will eventually lower US gas prices, but that relief is months away. Infrastructure funds now capture 77% of new climate capital, suggesting investors are betting on a structural shift even if consumers remain on the roller coaster McNally described.
Behind the numbers lies a question that will define energy policy for the next decade. Can renewables sustain their new share when the Strait of Hormuz reopens and gas prices fall? The April data offers a glimpse of what is possible.
It does not offer a guarantee. The UK and France-led military push to reopen the strait is the most immediate variable. Success would restore gas flows and likely depress prices.
That would test whether the solar and wind capacity added during the crisis remains competitive or gets idled. Failure would extend the crisis and accelerate both renewable deployment and coal consumption—a strange pairing that defines this moment. Both sides claim victory.
Here are the numbers. Wind and solar generated 22% of global electricity. Gas generated 20%.
Coal's share rose in Asia but the global data is still being compiled. The International Energy Agency has not yet released its April assessment. When it does, the coal number will complete the picture.
Why It Matters: The April milestone is the first real-world stress test of whether renewables can displace fossil fuels during a supply crisis. The answer is a qualified yes—they can, but only when gas is too expensive to compete, and only alongside a coal resurgence that undermines the climate benefit. For policymakers, the lesson is that renewable deployment accelerates fastest when fossil fuels become unreliable or unaffordable, not when climate targets demand it. - The milestone was driven by the Strait of Hormuz blockade, which cut LNG supplies and made gas unaffordable for many grid operators. - The same price shock pushed Asian countries back to coal, the cheapest baseload option, creating a parallel surge in both renewables and coal. - Former White House energy adviser Bob McNally warned the shift may reverse when oil and gas prices fall, calling the energy transition a "roller coaster."
The coming months will test whether April was an anomaly or a turning point. The Strait of Hormuz military operation's outcome is the single biggest variable. A reopening would likely restore gas to its dominant position in global electricity generation.
A prolonged closure would force more solar and wind deployment, but also more coal. The IEA's April data release will provide the first official confirmation of Ember's findings. Until then, the numbers stand as a snapshot of a world scrambling to keep the lights on.
Key Takeaways
