Poland and Ukraine are increasing this year’s production of thermal coal, the most polluting fossil fuel, preparing for colder months as Europe grapples with an energy security crisis exacerbated by the war in Ukraine.

Coal use as fuel for thermal power plants must also decline if the world is to meet net zero emissions targets by the middle of the century, but since the Russian invasion of Ukraine and the European sanctions on Moscow, the flow of Russian gas to Europe has decreased.

The future of solar panels may lie in coffee. Researchers at the University of California, Los Angeles (UCLA) and Solargiga Energy in China recently published the results of research in which they saw improved thermal stability of perovskite solar cells and their efficiency increasing from 17% to 20%. This was achieved by applying caffeine on the perovskite layer.

The idea began as a joke over morning coffee, the researchers said in an interview. “One day, as we were discussing perovskite solar cells, our colleague Rui Wang said: ‘If we need coffee to boost our energy then what about perovskites?
