Germany Experiences Decline in Wind and Solar Power Production

Germany's wind and solar power production has fallen to its lowest level in a decade, reaching only 80 TWh in the first four months of 2025, according to data from climate think tank Ember. Consequently, the country's gas and coal generation has increased by 10% from last year, raising the share of hydrocarbons in its energy mix to the highest level in seven years.

The primary cause of the decline in wind and solar output was low wind speeds, which severely impacted wind energy generation, dropping it by 31% year-on-year to 39 TWh, the lowest since 2017, despite a 30% increase in wind turbine installations since then.

Looking ahead, Ember anticipates further deterioration, with low wind speeds likely to continue in the warmer months, increasing reliance on coal and gas. Coal power output rose by 16% year-on-year in the first four months to 40 TWh, while gas generation fell by 9% due to high prices. However, this could change as gas prices have decreased from their peak earlier this year.

Conversely, gas prices might rise again soon as Europe prepares to refill storage facilities for the upcoming winter season, which sees peak demand. Meanwhile, solar power output increased in early 2025 and is expected to rise further with more sunshine during late spring and summer. It remains uncertain whether this will offset the seasonal lows in wind power generation.
