Looked at another way, shale natural gas has largely displaced coal which emits more CO2 and can be burned in the same power plants. This base load allows for more wind and solar. Natural gas is a great bridge fuel.
When the natural gas is displacing coal by being cheaper, that's pretty bad in the long run. We're still probably going to use that coal later, and cheaper fossil fuels reduce the price pressure to install renewables.
Higher prices would promote a faster shift directly from coal to solar (or nuclear if the price works out). And there was already enough natural gas production to fill the gaps that solar, wind, and batteries can't fill.
I don't believe nat gas is burned in the same plants as coal.
here's a decent recap (now a couple years out of date)
