As states use less coal for electricity, driving electric vehicles becomes even cleaner

Green Car Congress

These results indicate that coal and oil are the energy sources leading to most emissions, and that hydro, wind, and nuclear are the energy sources leading to least emissions. On the two extremes, coal and oil result in about 176 times the emissions from hydro.

As states continue to use less coal for electricity, driving electric vehicles becomes even cleaner

Green Car Congress

These results indicate that coal and oil are the energy sources leading to most emissions, and that hydro, wind, and nuclear are the energy sources leading to least emissions. On the two extremes, coal and oil result in about 176 times the emissions from hydro. Therefore, the data for 2008 are included here as well. from coal.

Udokan Copper to cut carbon intensity of copper production up to 75% by 2035

Green Car Congress

It will also study opportunities to switch from coal to less carbon-intensive fuels for heat generation as well as electrification of the mining fleet. Udokan Copper (earlier known as Baikal Mining Company) was established in 2008 to develop the Udokan copper deposit. In 2021, Udokan Copper invested RUB 764 million (US$11.5

MIT study concludes that absent climate policy, coal-to-liquids could account for around a third of global liquid fuels by 2050

Green Car Congress

A new assessment of the viability of coal-to-liquids (CTL) technology by researchers from the MIT Joint Program on the Science and Policy of Global Change (JPSPGC) found that without climate policy, CTL has the potential to account for around a third of global liquid fuels by 2050.

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 study was published online 24 May in the ACS journal Environmental Science & Technology. The study examined the fuel-cycle CO 2 , SO 2 , and NO x emissions of EVs in China in both current (2008) and future (2030) periods and compared them with those of conventional gasoline vehicles and gasoline hybrids.

Study Finds that US Subsidies for Fossil Fuels Are Almost 2.5x Those for Renewables

Green Car Congress

US subsidies for fuels and renewable energy, 2002-2008. The study, “Estimating US Government Subsidies to Energy Sources: 2002-2008”, found that fossil fuels benefited from approximately $72 billion over the seven-year period, while subsidies for renewable fuels totaled $29 billion. Nuclear was not included in the analysis.
