A quick google shows that natural gas is generally capitalised whereas the rule for chemical elements seems to be that they are not. I am writing a text that includes Natural Gas (I cannot replace that with methane) and chemical elements such as helium. I find it odd to capitalise Natural Gas and not helium.

What is the correct way to spell Natural Gas?

  • Because "Natural Gas" is not just any natural gas. Let me know if you need more detailed explanation.

    "A quick google shows that natural gas is generally capitalised" Your Google must be different from mine. Dec 20, 2018 at 9:42
  • You only capitalize it if you're making money off of it.

Wikipedia writes it in lower-case.

All the dictionaries I have searched write it in lower-case.

(That would be Merriam-Webster, dictionary.com, the Free Dictionary and the Collins Dictionary.)

The only cases you would write it in capital letters would be in a title or name, e.g. the Natural Gas Association.
