Europe’s Solar Power Boom Saves €37.4 Billion in Gas Imports Amid Iran War

Europe’s growing reliance on solar energy has helped the European Union (EU) avoid an estimated €37.4 billion in gas import costs since the Iran war began, highlighting the economic benefits of renewable energy amid rising fossil fuel prices.

The estimate was reported by Euronews on October 2, 2026, citing analysis from SolarPower Europe, the industry association representing Europe’s solar power sector. The savings reflect gas imports avoided because solar-generated electricity reduced the need for gas-fired power generation.

The conflict in the Middle East has disrupted energy markets and heightened concerns about Europe’s dependence on imported fossil fuels. Solar energy has helped cushion the impact by supplying electricity without requiring fuel imports.

According to SolarPower Europe, cumulative savings from avoided gas imports had already exceeded €30 billion by September 2021? No—by September 2026, approximately six months after the conflict began. The subsequent €37.4 billion estimate reflects the continued contribution of solar generation and elevated gas prices.

The savings are not necessarily direct cash payments received by European governments or households. Instead, they represent the estimated cost of gas that Europe did not need to import to produce electricity.

Solar power has expanded rapidly across Europe, helping reduce the role of fossil fuels in electricity generation. In June 2026, solar supplied approximately 25% of the EU’s electricity, becoming the bloc’s largest single source of electricity for that month, according to SolarPower Europe.

The benefits extend beyond avoided fuel purchases. When solar generation displaces more expensive gas-fired power plants, it can also reduce the influence of gas prices on wholesale electricity markets.

However, the extent of those benefits varies with weather conditions, electricity demand, the availability of other power sources and the ability of national grids to distribute renewable electricity. Despite the savings, Europe remains exposed to volatile international energy markets. Natural gas continues to play a role in electricity generation, heating and industrial activity.

Solar output also varies with daylight and weather conditions, making battery storage, stronger electricity grids and other flexible energy sources important for maintaining reliable supplies.

The European Environment Agency has similarly highlighted the importance of combining renewable generation with storage, grid improvements and demand management to reduce exposure to gas price volatility.

Europe’s experience illustrates how investment in renewable energy can reduce exposure to international fuel price shocks. For countries that depend heavily on imported energy, expanding domestic renewable generation may help limit fuel costs and strengthen energy security.

For Nigeria, which faces persistent electricity supply challenges and relies on fuel-powered generators across many homes and businesses, the broader lesson is the potential value of developing reliable domestic energy alternatives. However, the European savings figure should not be assumed to translate directly to Nigeria, whose electricity market, infrastructure and energy needs are different.

Europe’s estimated €37.4 billion in avoided gas imports demonstrates the growing economic significance of solar power. The longer-term challenge will be sustaining that progress through investment in generation, storage and electricity infrastructure.
