The sun is likely to become the world's most important source of energy before 2050, according to British scientists. This is the result of an analysis of technological and economic data by the University of Exeter and University College London.

Researchers have come up with the vision of a pumped storage power plant of a special kind. Their idea involves a type of cable car that can be used to transport sand or gravel up mountains in order to generate electricity when required by transporting it down the mountain again.

Scientists in Singapore have developed a low-cost device that can harness the energy of light breezes and store it as electricity.

At high altitudes the wind is much stronger. Empa researchers want to harness the energy slumbering in the wind with the aid of kites. The technology would be particularly suitable for generating electricity in remote areas.

A Swiss research team has succeeded in increasing the efficiency of perovskite silicon tandem solar cells to over 30 percent. This is a world record.

Whether when typing, moving, or walking, scientists are investigating how devices recognize users by their behavior.

Scientists have developed a new method to convert plastic waste into hydrogen through pyrolysis, a high-temperature chemical process.

ETH Zurich has put an artificial sun into operation. In the room of a new laboratory, the sun shines at the push of a button, just as it does at midday in the Sahara or in January in Berlin.

Researchers want to use chicken feathers to produce green electricity. They use the keratin in chicken feathers to replace highly toxic chemicals in fuel cells.

Shipping leaves a large ecological footprint: the propulsion engines are largely dependent on energy sources that produce climate-damaging CO2 when burnt. In addition to hydrogen and methanol, ammonia is also considered a more climate-friendly substitute fuel.
