Light out for climate protection: Earth Hour 2025 in Hessen!

On March 22, 2025, the Earth Hour will take place worldwide, which begins at 8:30 p.m. In Hesse, numerous people will switch off the light for an hour to set a strong sign of climate protection. The aim of this global action is to motivate politics, business and private individuals to act more sustainably, especially with regard to renewable energies. A report by Statistik.hessen.de emphasizes that Hessen achieved gross current generation of 18.1 Terawatt hours (TWH), of which 49.1% came from renewable energies.

The renewable energies that contribute to electricity generation in Hesse are wind power, photovoltaics and biogas. Over 46.9% of the energy generated comes from wind power, followed by photovoltaics with 26.3% and biogas with 11.6%. Compared to 2017, this represents a decline in the share of renewable energy sources, which was 43.5% at the time. However, the development has shown an increase of 20.7% since then. Despite this progress, electricity generation in Hesse 2022 was lower than the electricity requirements of 37.8 TWh.

renewable energies and energy consumption in Hesse

In 2022, 52.1% of gross electricity consumption were covered by imports. The final energy consumption in Hessen was 732.4 Petajoules and increased by 3.0% compared to the previous year. Renewable energy sources made up only 5.9% of the final energy consumption, with more than half of the energy consumption loss of mineral oil products. Gas represented the most used energy source in Hesse with a share of 58.4%.

For new apartments from 2016, 26.5% were heated with renewable energies, while gas heaters were installed in 36.5% of new buildings. Another aspect is that only 13.8% of the 3.13 million apartments in Hesse were heated with renewable energies, which illustrates the challenges in the area of ​​sustainable heat supply.

Current developments in wind power expansion

The development of wind energy in Hesse has improved in recent years. According to a report by bundes- government.de , are part of an overarching goal of reducing the dependency on conventional energy sources.

For the further expansion of wind and solar energy, the new legal framework, the faster permits and the creation of additional positions to process applications are of great importance. These measures form a solid basis for future energy supply in Hesse and beyond.
