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. from coal. Energy source. Natural gas. Natural gas. Geothermal.

CSIRO study finds little to no environmental impact from fracing in Queensland

Green Car Congress

A comprehensive three-year scientific study into the air, water and soil impacts of hydraulic fracturing (HF) in coal seam gas (CSG) in Queensland, Australia has found little to no impacts on air quality, soils, groundwater and waterways. CSIRO scientist sets up a solar-powered air-quality-monitoring station in the Surat Basin, Queensland.

GWU team develops cost-effective solar process to produce lime for cement without CO2 emission

Green Car Congress

Conventional thermal decomposition production of lime (left) versus STEP direct solar conversion of calcium carbonate to calcium oxide (right). Conducive to our new solar process, electrolysis of molten carbonates forms oxides, which precipitate as calcium oxide when mixed with calcium carbonate. Click to enlarge. —Licht et al.

Study finds shifts to renewable energy can drive up energy poverty

Green Car Congress

Efforts to shift away from fossil fuels and replace oil and coal with renewable energy sources can help reduce carbon emissions but do so at the expense of increased inequality, according to a new study by researchers at Portland State University (PSU) and Vanderbilt University. —Julius McGee.
