25 Jan 2013. Rush to Natural Gas has Coal-fired utilities Seeing Red. Wall Street Journal.
Electricity from Natural Gas is now 30%, up 12% from 10 years ago (18%). From coal: now 37%, down 13% from 10 years ago (50%)
U.S. electricity in trillions of kWh (kilowatt hours):
- Coal 1.7 Trillion
- Natural Gas 1.0 Trillion
- Nuclear .79 Trillion

Only 3 states buy gas under contracts longer than 3 years (OR, CO, OK).
