Net public electricity generation reached a record share of 59.7 per cent in 2023. The share of the load was 57.1 per cent. This is the result of an analysis presented today by the Fraunhofer Institute for Solar Energy Systems ISE. New records were set for wind and solar power in 2023. In contrast, generation from lignite (-27 per cent) and hard coal (-35 per cent) fell sharply. Photovoltaics stood out in the expansion of generation capacity: at around 14 gigawatts, the expansion was in double digits for the first time and significantly exceeded the German government's statutory climate protection target.

Germany can still achieve its climate targets by 2030. This is shown in a new analysis by the Federal Environment Agency (UBA). This would require, among other things, more rail transport, a reform of the motor vehicle tax and the restriction of fossil heating. In addition, all emissions would have to be priced and charged to the polluter. In the so-called Climate Protection Instruments Scenario 2030 (KIS-2030), the UBA has examined how additional emissions can be saved in the building, mobility, energy and industry sectors. "The model calculation clearly shows that we have a lot of catching up to do in some sectors," says UBA President Dirk Messner. "We now urgently need a constructive dialogue about where emissions can be reduced, otherwise we will miss the legal savings targets. We also need to talk honestly about how to cushion the financial burden on lower-income groups and distribute it more fairly. Currently, low-income households are often asked to pay disproportionately. Understandably, this does not exactly increase acceptance for more climate protection.

15 % of deaths in Europe are due to environmental risks, the WHO estimates. Health hazards arise, for example, from air pollutants, noise, chemicals and the spread of antibiotic resistance. New burdens, such as those caused by climate change and biodiversity loss, are also emerging. 

The housing projects presented in Vienna arose from the desire to develop living concepts that strengthen the sense of community and contribute to a society based on solidarity - building groups and participatory projects, neighbourhood houses, temporary or permanent social forms of living and working for marginalised groups such as the homeless and asylum seekers. Private housing can be downsized if there is more shared space. These housing and living models are about alternatives to capitalist investor thinking. The users get involved, also in the project planning. Ulrike Schartner and Alexander Hagner from gaupenraup+/- explain the starting point and strategies of their work in an introductory interview. In two essays, Robert Temel and Isabella Marboe show the development of communal building and living forms.

The construction volume "Commercial Buildings in Clay and Wood - Added Value through Material" was published in 2020 by Sabine Djahanschah of the Deutsche Bundesstiftung Umwelt (German Federal Foundation for the Environment) at Verlag Detail. The publication, which appeared in book form, deals with the use of the building materials wood and clay in the construction of commercially used buildings. To this end, six buildings with commercial use were analysed in terms of their architectural construction and technical quality features and evaluated with the help of measurements, surveys and life cycle assessments.
