US power mix: Gas relpacing coal faster than expected
Coal has been the dominant source of electricity in the U.S. power mix for more than a century, but that may be coming to an end sooner than expected. For only the second time ever, but also the second time this year, gas generated more electricity in the U.S. than coal. According to statistics from the Energy Information Administration, in July 2015 coal generated 139 TWh, while natural gas generated 140 TWh. Some of the dip in coal's share is likely the result of the final compliance deadline for the Mercury and Air Toxics Standards in April 2015.
