Gas is kinda easier to replace though. As you can burn other Gases instead of Natural Gases with a few modifications to the Powerplant.

Natural Gas is such a weird PR term coined by fossil industry. I think the term "fossil gas" is much clearer.

Well, the term "natural gas" is ~200 years old and was invented to distinguish it from manufactured coal gas. But other than that, you're right. It's getting tiring having to explain to people why biogas isn't "natural gas".
