Nonrenewable fossil fuels are a waste of energy and pollute, but there are both natural and artificial means to undo the damage, sequester the carbon, or produce gas out of biofuels etc.
When you use helium, it literally floats to the top of the atmosphere and escapes into space. It's never, ever coming back. It's a totally different class of "nonrenewable".
- nradov 5y agoIf we don't use the helium then natural gas producers just vent it into the atmosphere anyway. Helium is somewhat renewable because more is constantly created by underground decay of radiative isotopes.
