Picky quibble:

Uses for gas turbine electricity production is largely LPG.

You mean “LNG” — liquefied natural gas, methane, CH4.

LPG is “liquefied petroleum gas” — propane and butane, C3H8 and C4H10. They’re both primarily side effects of petroleum refining.

But your poiint is correct.

Also, electric power production with gas gives complete combustion, so there aren’t as many side pollutants, like NOx.
