Gas for both heating and electricity is a single point of failure.
I’m starting to see the merit of the oil furnace with a big oil tank. You are not at the mercy of some centralized infrastructure.
Which sounds great unless you are one of the vast majority of oil heat users who have an electric ignition on the oil burner that stops working during a blackout.
Oil furnace and large oil tank are useless without power to run it.
People new a big freeze was coming so you plan ahead.
Coal, baby! (Well in the northeast, anyway.)
“A ton of anthracite, a particularly high grade of coal, can cost as little as $120 near mines in Pennsylvania. The (heat) equivalent amount of heating oil would cost roughly $380, based on the most recent prices in the state and over $470 using prices from December 2007. An equivalent amount of natural gas would cost about $480 at current prices.”

For 1/3 the price of of oil and 1/4 the price of NG, many in the northeast do still use coal.
A big honking propane tank is the functional equivalent. But the "centralized infrastructure" is still there..just at one remove. The place where I lived in Washington (state) had a 100 gal propane tank and propane fireplace..all electric otherwise. That fireplace saved our asses more than once (electric service VERY unreliable). And, having come from south Louisiana, I already knew the value of backup for lights and cooking from hurricane preparedness.
We moved from Washington to San Antonio last year, and haven't had a chance to fully "prep up" for the new place...yet!
Don’t debase yourself with oil, get propane instead.
