CMU study finds that coal retirement is needed for EVs to reduce air pollution

Green Car Congress

Electric vehicles charged in coal-heavy regions can create more human health and environmental damages from life cycle air emissions than gasoline vehicles, according to a new consequential life cycle analysis by researchers from Carnegie Mellon University.

The Complex Calculus of Clean Energy and Zero Emissions

Cars That Think

—Jesse Jenkins, Princeton University When I entered the field, commercial wind was starting to scale up and the questions were about engineering feasibility. What was the maximum share of wind that we could have in the system without blowing it up—5 percent or 20 percent or 30 percent? What about the pitfalls with energy modeling?

Mercedes-Benz Cars plants in Germany to be supplied with CO2-neutral energy from 2022

Green Car Congress

Thereby, we completely forego coal-based electricity and obtain our electrical energy from only renewable sources. In the future, 100% of additional purchased electricity will come from verifiable renewable sources, such as wind- and hydropower. This corresponds to about three quarters of the required electricity in the German plants.

EPA Proposes Transport Rule to Cut Pollution from Power Plants in 31 States and DC; New Approach for Pollution Reduction

Green Car Congress

These pollutants are carried on the wind to other states, contributing to health problems for their residents and interfering with states’ ability to meet air quality standards. To meet this proposed rule, EPA anticipates power plants will: Operate already installed control equipment more frequently; Use lower sulfur coal; or.

Researchers demonstrate electrochemical synthesis of ammonia from air and water under mild conditions

Green Car Congress

Andrews have demonstrated that ammonia can be synthesized directly from air (instead of N 2 ) and H 2 O (instead of H 2 ) under a mild condition (room temperature, one atmosphere) with supplied electricity which can be obtained from renewable resources such as solar, wind or marine. tons of CO 2 is released per ton of ammonia produced.

Energy Secretary Chu says US faces a new Sputnik Moment in Chinas clean energy successes

Green Car Congress

China has deployed the world’s first Ultra High Voltage AC and DC lines—including one capable of delivering 6.4 Advanced Coal Technologies. China is installing wind power at a faster rate than any nation in the world, and manufactures 40% of the world’s solar photovoltaic (PV) systems. Renewable Energy.

EPA proposes rule for nationwide 30% cut in GHG from existing power plants by 2030 relative to 2005

Green Car Congress

Vermont and Washington, DC are not included in this rule because they do not have fossil fuel-fired power plants. The value allocated here in EPA’s goal-setting formula was an average heat rate improvement of 6% for coal steam electric generating units (EGUs). the remainder from other sources, including wind and solar.
