and NuCoal Energy Corporation recently executed a Memorandum of Understanding (MOU) wherein Sparton and NuCoal will jointly evaluate the potential of NuCoal’s lignitic coal holdings in Saskatchewan to host commercial germanium and uranium mineralization. The quantities are dependent on the amounts of metal contained in the coal feedstock.
In addition to its regional and temporal scope, this study is distinct from earlier LCA literature in four key aspects: This study considers the lifetime average carbon intensity of the fuel and electricity mixes, including biofuels and biogas. Source: The ICCT.
Oil demand grew by less than 1%—the slowest rate amongst fossil fuels—while gas grew by 2.2%, and coal was the only fossil fuel with above average annual consumption growth at 5.4% Coal was again the fastest growing fossil fuel with predictable consequences for carbon emissions; it now accounts for 30.3% globally, and 8.4%
Small amounts of biofuels, electricity, and coal were also imported. Exports of primary energy from the United States were led by petroleum products (48%), followed by crude oil, natural gas, and coal, with small amounts of biofuels and electricity. Coal category includes coal coke. type jet fuel, kerosene?type
Gasoline section shows results for fuel derived from both conventional oil and oil sands. The study also highlights that upstream CH 4 (methane) leakage and venting is a key contributor to the total upstream emissions of natural gas pathways, and can significantly reduce the life-cycle benefit of natural gas compared to coal or petroleum.
by Michael Sivak, Sivak Applied Research The overall advantage of battery electric over gasoline vehicles, in terms of well-to-wheels emissions of greenhouse gases, has been well documented. However, the emissions of electric vehicles depend greatly on the energy source used to generate the electricity that powers them.

The Ugly Coal sucks, there's really no two ways about it. But not all use of coal is alike. The Good About half our electricity comes from coal, and that will change, at best, slowly as we move to renewables. That includes the worst, most coal dependent areas.
The decrease was driven by the economic downturn, combined with a significant switch from coal to natural gas as a source of electricity generation, according to the EIA. The EIA projects that fuel switching in the electric power sector and declines in industrial use will lead to a 7.9% increase in coal CO 2 emissions in 2010.
Stay-at-home orders, travel restrictions, and work-from-home arrangements reduced demand for motor gasoline, distillate fuel oil (primarily consumed as diesel), and jet fuel. Compared with petroleum and coal, EIA expects a relatively smaller decline in natural gas consumption and its related CO 2 emissions (both 4% lower) in 2020.
A new report from the National Research Council examines and, when possible, estimates, “hidden” costs of energy production and use—such as the damage air pollution imposes on human health—that are not reflected in market prices of coal, oil, other energy sources, or the electricity and gasoline produced from them.
