Business Insider reported on natural gas slowly taking over coal as the dominant fuel for power generation. The low prices of natural gas and the introduction of new turbine technologies, as well as legislation in Congress mark the rise of natural gas usage over coal.
As quoted in the report:
Higher natural gas prices—a certainty, given that they’re currently below production costs—will have some impact on the speed of the progression of natural gas. In the short term, power generators switch between fuels to take advantage of lower costs here and there. But as more gas-fired plants have come on line, and as the oldest, most inefficient coal plants are being retired, the shift to natural gas has become structural—pushing up demand inexorably.
