A study examining the historic prices of fossil fuels and renewable technologies suggests coal, oil and gas might not actually be as cheap as commonly thought.
With their combed front edge and fringe at the back, owl wings could serve as the ideal model for quieter wind turbines.
In Germany, the rate of construction of new wind turbines has slowed dramatically - which could have fatal consequences for the energy transition. One of the reasons that new turbines face opposition is that the giant blades endanger near-flying birds. BirdVision is tackling the problem with the help of AI.
Higher, more efficient and definitely more mobile - students at the ETH Zurich are breaking new ground with a special airborne device for harvesting energy from the wind.
What do you need to build a wind turbine? Bits of an old printer, plastic buckets or bowls - and wind of course. Armed with enough innovation to impress even MacGyver, a professor in Vietnam has come up with an idea that has changed the lives of an entire village.
