FWIW, we were at around $0.50 / therm in the 90s. In 1990s dollars.
I put in dual fuel (heat pump with a natural gas furnace) system about 10 years ago because of the high price of natural gas.
During Trump, I was wondering about the wisdom of that choice, natural gas was so cheap due to fracking.
Today, I’m thinking a dual fuel system is a good hedge, plus a wood burning stove.
People need to look securing their heating sources.
I was spot heating with a kerosene heater back in the early 2000s, and doing quite well with it.
Then the Green children in ClownBammy's goobermint mandated low-sulfur diesel/kerosene...
Of course, we have backup...another wood burning stove.
