Sun and Wind Are Free. So Why Are German Power Bills Among Europe's Highest?

Germany generated more electricity from wind and solar in 2025 than any other EU country. It accounted for more than a quarter of the bloc's total wind and solar generation. Clean sources made up 59% of its electricity mix. Yet German households pay around a third more for electricity than the EU average – €0.39 per kilowatt-hour including taxes and levies, compared to the EU average of €0.29.

Only Ireland, at €0.40 per kWh, has higher prices.

The paradox has a name: the merit order principle. It ensures that electricity prices are based on the most expensive power plant still needed to meet demand. If Germany's electricity needs cannot be covered solely by clean energy, more expensive and polluting sources such as coal or gas step in – and they set the price for everyone.

Germany's rapid renewable expansion has not broken this link. The country's share of generation from wind and solar alone rose from less than two percent in 2000 – when its landmark renewable energy law was introduced – to almost 45 percent last year. Coal fell from supplying more than half of Germany's electricity to just 21 percent. But fossil fuels still determine the marginal price.

Adding more renewables can solve this problem. Spain proved it: wind and solar growth have reduced the influence of fossil generators on electricity prices by 75 percent since 2019. Spain had a similar share of electricity from wind and solar as Germany in 2025, but other clean sources such as hydropower and nuclear significantly reduced its reliance on fossil fuels. Clean energy made up 75 percent of Spain's electricity mix, compared to 59 percent in Germany.

Germany also faces a flexibility problem. According to Jannik Schall, co-founder of energy firm 1KOMMA5°, "Germany does not have too much cheap wind and solar power, but too little flexibility in the system." Last year, Germany spent €435 million on renewable energy curtailment – intentionally shutting down electricity production in areas of oversupply and ramping up supply elsewhere. This happens when ideal conditions for solar and wind result in more electricity being produced than the grid can handle. When supply outstrips demand, negative energy prices can occur.

Europe's energy grid was never designed for the renewables boom. It was built for centrally located plants. Wind and solar energy, often produced in remote areas, frequently cannot reach homes and offices. Battery energy storage systems (BESS) have been touted as a solution. According to a 2026 Solar Power Europe report, despite a tenfold expansion of the EU battery fleet since 2021 – reaching more than 77 gigawatt-hours today – Europe remains "far from where it needs to be." To meet 2030 targets, the EU must scale battery storage to 750 gigawatt-hours within five years. Germany and Italy are leading the race, accounting for more than 60 percent of new BESS capacity in 2025.

Germany's electricity prices are also heavily influenced by costly grid fees and taxes. 1KOMMA5° found that households would only be paying €0.26 per kilowatt-hour if not for levies – lower than in Belgium, Luxembourg, and the Netherlands. "We could significantly reduce grid charges if redispatch measures were better avoided," Schall said, referring to the short-term shutdown or start-up of power plants. "Instead of shutting down generation plants for compensation, an intelligent control system enables the forward-looking shifting of electricity volumes between storage systems and flexible consumers. This reduces grid costs for everyone in the long term."

A typical single household consuming 1,500 kilowatt-hours per year pays around €150 more annually than the EU average. A family with 5,000 kWh consumption pays an additional €500. The gap is not lost on German voters – or on policymakers who have spent decades championing the Energiewende, the country's energy transition.

The solution, experts say, is more renewables and more storage. But until the merit order principle is broken and the grid becomes flexible enough to handle peak production, Germany's electricity prices will remain tied to the very fossil fuels it is trying to leave behind. The sun shines. The wind blows. The bills keep arriving. And German households are left wondering: if we are leading the world in clean energy, why does it still cost so much?
