New simulations of wind power generation

and has no comments yet.
There has been a massive boom in wind power capacity both in Europe and worldwide. In 2015 global installed capacity was around 350 gigawatt (GW), with 135 GW installed in Europe, distributed across some 87,000 wind turbines. Wind power now provides a bigger share (13 percent) of electricity than nuclear power stations. In countries such as Spain, Denmark and Germany, the amount of wind power already installed is in theory enough to cover nationwide demand for electricity under ideal conditions, i.e. maximum wind power output and low consumer demand.

Solid batteries improve safety

and has no comments yet.
Lithium-ion batteries store a lot of energy in a small space, making them the energy source of choice for mobile electronic devices. Today, mobile phones, laptops, e-bikes and electric cars are all powered by such batteries. Researchers at ETH Zurich have now developed a type of battery that, unlike conventional ones, consists entirely of solid chemical compounds and is non-flammable.Conventional lithium-ion batteries are not without their dangers: mobile phone batteries have exploded several times in the past, resulting in injuries, and only six months ago an entire row of houses burned down in the old town of Steckborn on Lake Constance. The blaze was caused by a model-making battery that allegedly caught fire due to being charged improperly.
