Study finds climate impact of hydropower varies widely

Green Car Congress

earlier post ), a new study by a team at Environmental Defense Fund finds that the climate impact of hydropower facilities varies widely throughout the world and over time, with some facilities emitting more greenhouse gases than those burning fossil fuels. They also estimated emissions caused by flooding the reservoir.

Volkswagen outlines coming changes to charging for its EVs

Green Car Congress

Charging and energy are becoming a core business for Volkswagen; the company is building a universal and seamless eco-system for charging its electric models. This means, for example, that wind turbines won’t need to be shut down because there isn’t anyone using them. Volkswagen intends to be climate-neutral by 2050 at the latest.

Stanford study finds current carbon capture technology inefficient & increases air pollution

Green Car Congress

Jacobson, professor of civil and environmental engineering at Stanford University, suggests that carbon capture technologies are inefficient and increase air pollution. Wind replacing fossil fuels always reduces air pollution and never has a capture equipment cost. Only when wind replaced coal itself did social costs decrease.

Global Carbon Project: Global carbon emissions growth slows, but hits record high

Green Car Congress

Driven by rising natural gas and oil consumption, levels of CO 2 are expected to hit 37 billion metric tons this year, according to new estimates from the Global Carbon Project (GCP), an initiative led by Stanford University scientist Rob Jackson. In 2019, consumption of coal is expected to drop 11% in the U.S.—down Peters, R.M.

CESifo: EVs not the best option for reduction in on-road CO2 in Germany given power mix

Green Car Congress

Unfortunately, due to our grid situation, electric cars are still too early for this strategic goal in the sense of German climate protection efforts. The idea of providing the necessary storage of wind and solar energy with batteries is utopian, as the Leopoldina, Acatech and the Union of Academies of Sciences have emphasized.
