This decline was due almost entirely to a drop in coal consumption. Coal-fired power generation fell by a record 18% year-on-year to its lowest level since 1975. An increase in natural gas generation offset some of the climate gains from this coal decline, but overall power sector emissions still decreased by almost 10%.
My favorite part of this next CicLaVia is t he Bike Parade coming from my friends at Greenpeace and Sierra Club which they’re calling ROLL AGAINST COAL. In case you didn’t know, the City of Los Angeles still gets 40% of its electricity from coal-fired power plants, the dirtiest polluters and greenhouse gassers on the planet.
Researchers from SRI International (SRI) are developing a methane-and-coal-to-liquids process that consumes negligible amounts of water and does not generate carbon dioxide. In conventional CTL approaches, energy is supplied by burning a portion of the coal feed, which then produces carbon dioxide. Process flow diagram. Source: SRI.
US electric power sector CO 2 emissions have declined 28% since 2005 because of slower electricity demand growth and changes in the mix of fuels used to generate electricity, according to the US Energy Information Administration (EIA).

Natural gas will play a leading role in reducing greenhouse-gas emissions over the next several decades, largely by replacing older, inefficient coal plants with highly efficient combined-cycle gas generation, according to a major new interim report out from MIT. The first two reports dealt with nuclear power (2003) and coal (2007).
Oil accounts for most of this decline as, for the first time, global consumer spending on oil is set to fall below the amount spent on electricity. Electricity grids have been a vital underpinning of the emergency response to the health crisis – and of economic and social activities that have been able to continue under lockdown.
One of the common arguments you hear from people in America who are not fans of the idea of electric vehicles is that they are mostly charged from electricity produced from coal power plants. Heavy Coal Using States Accounted for Only 10% of EV Sales in 2020. of electric vehicle sales in the US. of sales.
The EMS (Earth and Mineral Science) Energy Institute at Penn State has developed a conceptual novel process configuration for producing clean middle-distillate fuels from coal with some algal input with minimal emissions.
