No one except a few miners will lament the loss of coal as a power source. It's dangerous to mine and filthy to burn. NG offers a cheaper and better alternative. While renewables have their place in the grid, particularly as individual residential installations, the new backbone of industry should be NG and nuclear.
Personally, I prefer nuclear in the form of new Gen IV reactors, but it is more expensive. I also favor solar panels on homes and small businesses. But what we need more than anything, of course, is a good way to store power. Perhaps Tesla will make even more progress on their batteries.
