EARTH TALK: DIRTY FUELS

 

Dear EarthTalk: What are “dirty fuels” and why are they so called?    -- Bill Green, Seattle, WA

February 25, 2014 (San Diego's East County) - The term “dirty fuels” refers to fuels derived from tar sands, oil shale or liquid coal. Just like their more conventional fossil fuel counterparts such as petroleum and coal, they can be turned into gasoline, diesel and other energy sources that can generate extreme amounts of particulate pollution, carbon emissions and ecosystem destruction during their lifecycles from production to consumption.
