Guillaume Albasini + 851 October 30, 2018 According to this interesting study, US Electricity customers in four competitive power markets paid at least $1 billion per year more than they needed to pay for their electricity over each of the last three years because utilities sold them power from their own coal-fired plants instead of from cheaper power sources on the grid., https://blog.ucsusa.org/joseph-daniel/the-coal-bailout-nobody-is-talking-about?_ga=2.118490505.1024418369.1540903129-2076229930.1539806212 2 Quote Share this post Link to post Share on other sites

If they shut down the coal power plants, natural gas will not be left in a monopoly situation. There is also solar and wind energy increasingly competitive to challenge natural gas. 1 Quote Share this post Link to post Share on other sites
