The conditions for renewables are good—but there is a need to catch up in terms of storage and sector coupling

Infografik of January 13, 2026

The infographic illustrates key developments in Germany’s energy transition in 2025. The title reads: “Supply of renewable energies on the rise, demand lags: electricity system needs more flexibility.” It highlights that photovoltaics grew faster than wind power in 2025. Onshore wind power is on track to meet its targets by 2028, while offshore wind power shows hardly any expansion yet but has ambitious plans. Electric mobility is progressing slowly, with fewer than one in five new car registrations being electric. Many new fossil fuel heating systems were still installed in 2025. Flexibility technologies such as storage grew more slowly than renewables. Electricity market prices were negative more often than ever before due to supply exceeding demand. At the bottom, the source is noted as “DIW Berlin 2026” with the statement: “The conditions for renewables are good—but there is a need to catch up in terms of storage and sector coupling.”
