Natural gas overwhelmingly dominates the U.S. electric power system, double second place coal. Gas is cleaner, cheaper, more flexible, and more reliable. Gas will supply over 40% of our power this summer and is racing toward being 50% of total generation capacity. Just think about the scale of that. For every 10o power plants in America that create electricity, 50 of them will run on natural gas (see Figure). Further, the International Energy Agency has specifically credited the rise of gas in our power system as the reason why we are slashing CO2 emissions faster than any other country ever.
