Europe’s electricity mix is getting cleaner, and with it, the climate advantage of electric cars is growing. According to new ICCT research, battery electric cars sold today produce 73 % less life-cycle greenhouse gas emissions than their gasoline counterparts — even when factoring in production. That’s a 24 % improvement over our 2021 estimates. In contrast, other powertrains, including hybrids and plug-in hybrids, show only marginal or no progress in reducing their climate impacts.

Piezoelectricity is an inherent property of certain materials. Strange as it sounds, piezoelectric materials generate current when they are mechanically stressed. Inverse piezoelectricity also exists, where materials change shape upon the application of an electric field. The article explores the role of piezoelectric materials in modern times.

A GaN charger is a very small charger that doesn't become hot to touch, even after continuous use. Conventional chargers in our homes and offices are made up of silicon.
