Why EVs Aren't a Climate Change Panacea

Cars That Think

Today, depending on the EV model, where it charges, and assuming it is a battery electric and not a hybrid vehicle, it may need to be driven anywhere from 8,400 to 13,500 miles , or controversially, significantly more to generate less GHG emissions than an ICE vehicle. The answer is perhaps some, but maybe not too much.

New wind farm and Tesla Megapack projects may reduce Australian coal use

Teslarati

An upcoming Tesla Megapack project and a new wind farm may help Australia reduce its use of coal power. Australia has long used coal as a power source, mainly because of its abundance. Currently, the country operates four Megapacks, the biggest being Victoria’s 450MWh Victorian Big Battery project.

Tsinghua University provincial-level lifecycle study finds fuel-cycle criteria pollutants of EVs in China could be up to 5x those of natural gas vehicles due to China’s coal-dominant power mix

Green Car Congress

In regions where the share of coal-based electricity is relatively low, EVs can achieve substantial GHG reduction, the team reports in a paper in the ACS journal Environmental Science & Technology. According to the 12 th Five-Year Plan of the China Coal Industry (2011?2015)

Tsinghua/Argonne Study Finds That Mass Use of EVs in China Could Result in Higher CO2 and Criteria Pollutant Emissions Than Conventional and Hybrid Gasoline Vehicles Due to Coal-Fired Generation of Electricity

Green Car Congress

The researchers found that while EVs do offer a very promising solution to energy issues due to their replacement of petroleum fuels, for now “ the high pollution levels of coal-fired power plants will trade off EVs’ potential energy benefits in China ”. The power of EVs is electricity from the grid.

U-M study: When, where, how electric delivery vehicles are charged has big impact on GHGs

Green Car Congress

A key point of the study is that both the emissions directly tied to charging the vehicles and emissions that result from manufacturing the batteries must be considered. Charging practices that shorten a battery’s lifetime will lead to early battery replacement, adding to the total greenhouse gas emissions associated with that vehicle.

IEA: carbon intensity of global energy supply has barely changed in last 20 years; “window of opportunity in transport”

Green Car Congress

The global energy supply became 6% cleaner from 1971 to 1990,in response to the oil shocks of the 1970s. Since 1990, however, the ESCII (2010 = 100) has remained essentially static, changing by less than 1%. The world must slow the growth of energy demand as well as make its energy supply cleaner, the IEA said. tCO 2 /TJ (2.39
