Compare the Cost of Fuel Use

(This page was updated April 23, 2026.)

On average, natural gas energy is somewhat cheaper to operate compared to electricity. It's true; natural gas is the cleanest of all fossil fuels, and it's so reliable and comfortable that you may just forget that you're doing something good for the environment (and your wallet, too).
