What a difference a year makes! What a difference an increase in the natural gas price of about $1.50 per thousand cubic feet makes.
Natural gas-fired generation is down 13.4% in the first 5 months of 2013, compared to the same period in 2012. Why? Coal generation is up 11% and is displacing gas. It's that simple.
Look no further than the above fact to understand why US carbon emissions are rising again after falling sharply from 2007 to 2012. EIA projects that energy related carbon emissions will be up more than 2% in 2013 and then rise again in 2014.
