Study finds steelmaking by electric arc furnace in US produces up to 75% less carbon emissions

Green Car Congress

Blast furnace steel, which represents about 70% of global steel manufacturing, is produced at large steel plants that use coal to melt raw materials into iron and then process it into steel.

Roskill: CO2 emissions from lithium production set to triple by 2025

Green Car Congress

The high emissions intensity of refining concentrate to lithium carbonate or hydroxide, in part driven by China’s power grid mix and reliance of coal. The low emissions output from mining equipment and on-site vehicles, despite their comparatively high energy intensity.

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. Click to enlarge.

3 Oil Majors That Bet Big On Renewables

Green Car Congress

As we have pointed above, ENI has the most ambitious climate change pledge with plans to lower its greenhouse gas emissions by 80% by 2050. Natural gas does produce about 28% less CO2 emissions than heating oil and 50% less than coal for the same amount of energy when burned.

IEEE Discusses 6 Simple Solutions to Climate Change at COP27

Cars That Think

Simple, effective solutions that can help lessen the impact of climate change already exist. Rahman, a power expert and professor of electrical and computer engineering at Virginia Tech , is the former chair of the IEEE ad hoc committee on climate change. It results in higher efficiencies: about 46 percent.

CMU policy briefs outline benefits and potential for adoption of electrified vehicles in the US

Green Car Congress

Further, drivers should not be encouraged to charge at night in coal-heavy regions. As the electric power grid becomes cleaner, as electric vehicles become cheaper and faster to recharge with longer range, and as policies adjust, electrification may offer benefits across the board, the brief notes.

Siemens presents three-point plan for implementing cost-efficient energy transition in Germany

Green Car Congress

In addition, despite the rigorous development of renewables, carbon dioxide emissions are increasing, because the energy mix increasingly includes coal-fired power plants that emit large quantities of CO 2 to compensate for weather-related fluctuations in power generation from renewables and the closing of nuclear plants.
