Imported wood combustion? Some say it’s fine..others disagree

By Dave Elliott

Many environmentalists are not keen on using imported wood pellets in old inefficient converted fossil-fueled plants. They say there are better ways to use biomass and better sources- local anaerobic digestion of biomass wastes and residues, along with Combined Heat and Power (CHP). Large-scale biomass conversion, and even co-firing with coal, is sometimes portrayed as an interim option, getting biomass use established, but not everyone is convinced that this helps build up support for local sourcing of biomass. It’s just a way to keep old power plants going, so as to avoid having to write off some sunk costs.  There is also the wider debate about the extent to which large-scale combustion of grown biomass, especially from forests, is net low carbon, given that it takes time for new growths to absorb emitted CO2. It’s even been claimed that using wood from trees might lead to more emissions net than from using coal, depending on the source of the wood: http://www.rspb.org.uk/Image/biomass_report_tcm9-326672.pdf

Do the math – no, the U.S. can’t punish Putin by exporting oil and gas

Since Russia has taken over the Crimea region of Ukraine, there have been several news articles written regarding the supposed ability of the United States (U.S.) to use our oil and/or natural gas as some sort of geopolitical weapon.  This weapon would somehow hurt Vladimir Putin (not Russian citizens) and probably help the Europeans and Ukrainians that buy natural gas from Russia. I link here a recent Bloomberg article (March 25, 2014) that is an example of an article that does not ask the most relevant questions on this topic. By not asking relevant questions and not using relevant data, the public is not being properly informed.
