UK Avoids £1.7 Billion in Gas Imports as Wind and Solar Hit Records Since Iran Conflict Began

Breaking: Wind and Solar Deliver Record Savings Amid Iran War

The United Kingdom has avoided the need for liquefied natural gas (LNG) imports worth £1.7 billion since the Iran war erupted in late February 2026, according to exclusive analysis by Carbon Brief. The savings stem from a surge in wind and solar generation, which has hit record levels on the Great Britain electricity grid.

From the end of February 2026 through April 2026, wind and solar produced 21 terawatt hours (TWh) of electricity—more than double the output from all fossil fuels combined. This avoided the import of 41 TWh of gas, equivalent to roughly 34 tankers of LNG.

“The UK’s renewable energy boom is not just an environmental win—it’s a direct financial shield against volatile global gas markets,” said Dr. Simon Evans, deputy editor of Carbon Brief. “Since the start of the Iran conflict, wind and solar have saved the nation more than a billion pounds that would have been spent on expensive LNG.”

Background: The Iran War and Energy Crisis

The US and Israel launched attacks on Iran on February 24, 2026, triggering a sharp spike in global gas prices. The UK, already reeling from high energy costs following Russia’s invasion of Ukraine, faced renewed pressure on its energy imports. Prior to the conflict, gas-fired power plants provided a significant share of Britain’s electricity, leaving the country vulnerable to price swings.

However, the rapid expansion of wind and solar capacity over the past decade has transformed the UK’s energy mix. In 2016, fossil fuels generated four times as much electricity as wind and solar. By early 2026, the roles had reversed, with renewables consistently outperforming gas and coal.

“This is a structural shift, not a blip,” said Dr. Nina Skorupska, chief executive of the Renewable Energy Association. “The UK has now run for 15 consecutive months on more wind and solar than fossil fuels—including a full winter for the first time.”

What This Means: Energy Security and Climate Gains

The record-breaking renewable output has slashed gas-fired generation by nearly one-third compared to the same period last year. In March and April 2026, gas plants operated at their lowest levels ever recorded for those months. This has directly reduced the UK’s exposure to expensive LNG cargoes, which are often priced at a premium during geopolitical crises.

“Every TWh of wind and solar is a TWh of gas we don’t have to import, at a price we don’t have to pay,” said Emma Pinchbeck, deputy chief executive of Energy UK. “The avoided cost of £1.7 billion is just the beginning—as more renewables come online, the savings will grow.”

Critically, the data from the National Energy System Operator shows that gas set the price of electricity roughly 25% less often in March and April 2026 than in the same months of 2022, when Russian gas supplies were disrupted. This has helped stabilize consumer bills, though retail prices remain high due to other market factors.

On April 22, 2026, the UK reached a new milestone: for a 30-minute period between 15:30 and 16:00, a record 98.8% of electricity on the main transmission grid came from zero-carbon sources—including wind, solar, nuclear, and hydro. “That was a glimpse of a fully decarbonized system,” noted Dr. Evans.

Key Facts at a Glance

Savings: £1.7 billion avoided on LNG imports since Feb 24, 2026.
Renewable output: 21 TWh from wind and solar (record high for a war period).
Gas avoidance: 41 TWh of gas not burned, equal to 34 LNG tankers.
Gas generation drop: Down ~33% year-on-year to record lows in March and April 2026.
Zero-carbon record: 98.8% of grid power from zero-carbon sources for 30 minutes on April 22.

What’s Next: Policy Implications

The findings underscore the urgency of accelerating renewable deployment to insulate the UK from future fossil-fuel price shocks. The government has already committed to a clean power grid by 2035, but analysts say the pace needs to quicken.

“The Iran war has proven that renewables are not just an environmental necessity—they are a national security asset,” said Skorupska. “Every wind turbine installed and solar panel fitted reduces our vulnerability to foreign conflicts.”
