LLNL’s Energy Flow Diagrams Show That The US Isn’t Moving The Needle On Climate Action

CleanTechnica EVs

In 7 years of electrification and deployment of wind and solar, the US barely budged the needle, in fact declining slightly to more wasted energy in 2016 and 2017 before improving again in 2018 and onward.

Wind-to-Hydrogen Tech Goes to Sea

Cars That Think

Wind and solar parks produce a large portion of their energy. Then, as now, wind farms are operating off the world’s coasts—but not all of these offshore sites are connected to the mainland via underwater power cables. Some of the wind farms instead sit in clusters more than 100 kilometers out at sea.

European Union adopts strategies for energy system integration and hydrogen; Clean Hydrogen Alliance

Green Car Congress

For example, this means a system where the electricity that fuels Europe’s cars could come from rooftop solar panels, while buildings are kept warm with heat from a nearby factory, and the factory is fueled by clean hydrogen produced from off-shore wind energy. The Renovation Wave will be an important part of these reforms.

Audi introduces new CNG A3 Sportback

Green Car Congress

With full gas tanks, the car has an NEDC range of up to 495 (307.6 Before the tanks are mounted in the car, they are pressure tested at 300 bar, far above the operating pressure of 200 bar. More than half of them sell biomethane produced entirely from waste, and this number is increasing.

Heating Buildings With Solar Energy Stored in Sand

Cars That Think

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. The intermittent nature of daylight and strong winds, however, is a stubborn problem. The apparent contradictions do not end there.
