Researchers have developed a new type of small-scale electric power generator able to produce alternating current through the cyclical stretching and releasing of zinc oxide wires encapsulated in a ...

It hasn’t been that long since humans figured out how to create power grids that integrated multiple generators and consumers. Ever since AC won the battle of the currents, grid operators have had to ...

In the future, Europe is to be dominantly powered by renewable energy. The expansion of wind and solar power capacity and the provision of sufficient power in winter are just two of the challenges ...
