Nine years ago, Britain generated nearly 75% of its electricity using natural gas and coal. In 2018, this dropped to under 45% – a remarkable transition away from fossil fuels in under a decade.
Fusion power has been the fevered dream of scientists, environmentalists and futurists for almost a century. For the past few decades, scientists have been attempting to find a way to create sustainable fusion reactions that would provide human beings with clean, abundant energy, which would finally break our dependence on fossil fuels and other unclean methods.
Inexpensive clean energy sounds like a pipe dream. Scientists have long thought that nuclear fusion, the type of reaction that powers stars like the Sun, could be one way to make it happen, but the reaction has been too difficult to maintain. Now, we’re closer than ever before to making it happen — physicists from the University of Tokyo (UTokyo) say they’ve produced the strongest-ever controllable magnetic field.
Physicists at the University of Arkansas have invented a nano-scale power generatorthat could potentially use the movement of graphene to produce clean, unlimited energy. Called a Vibration Energy Harvester, this development provides evidence for the theory that two-dimensional materials could be a source of usable energy.
A German town is now home to the world's tallest wind turbine. The 808-foot-tall turbine is part of a project expected to generate 10,500MWh annually, which would be enough to meet the needs of more than 1,000 U.S. households.
