As I run across news items with the latest data, I add them here.
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
Some prefer coal power plants, where coal can be stockpiled. Gas is hard to store in bulk near power plants, making plants dependent on natural gas pipelines that simetimes have delivery issues.
Only 3 states buy gas under contracts longer than 3 years (OR, CO, OK).
