Heating Buildings With Solar Energy Stored in Sand

Cars That Think

This sponsored article is brought to you by COMSOL. In a region known for long, dark winter nights, Polar Night Energy is building a system in the city of Tampere that can heat buildings with stored solar energy — all day, all night, and all winter long. This means that storing and distributing energy is as important as its generation.

UC Davis ITS researchers take a detailed look at water consumption and withdrawal requirements for ethanol

Green Car Congress

Water consumption intensity of ethanol from corn grain and crop residue and the avoided/displaced water use credits assigned to coproducts: DGS and electricity. In their paper, Mishra and Yeh analyze the lifecycle water requirement consumption and withdrawal requirements of ethanol produced from corn and from crop residue.

Energy storage: the key to a decarbonised future

Setec Powerr

This article will answer your confusion. Just like we put food in the refrigerator, we can store it for days or weeks without eating it immediately or discarding it. Mechanical storage systems are arguably the simplest, drawing on the kinetic forces of rotation or gravitation to store energy. So what exactly is energy storage?
