Audi introduces new CNG A3 Sportback

Green Car Congress

Its turbocharger with variable turbine geometry makes optimal use of the exhaust gas energy for early and harmonious torque development. The synthetic fuel is produced at the power-to-gas plant in Werlte from water and carbon dioxide using electricity generated by wind power. The A3 Sportback 30 g-tron 1.5

IEEE Discusses 6 Simple Solutions to Climate Change at COP27

Cars That Think

One type is the ultrasupercritical coal-fired steam power plant. Conventional coal-fired plants, which make water boil to generate steam that activates a turbine, have an efficiency of about 38 percent. Ultrasupercritical plants operate at temperatures and pressures at which the liquid and gas phases of water coexist in equilibrium.

EV myths busted: Are electric vehicles actually good for the environment?

Drive Electric

These vehicles use large traction battery packs to power the motor. Because EVs run on electricity, the vehicle emits no exhaust from a tailpipe and does not contain the typical liquid fuel components in ICEVs. If it’s manufactured on a ‘dirty’ power grid it becomes a major source of emissions over the EV lifecycle.
