I was renting a place while rehabbing my home. We completely removed the natural gas from our house and went induction range, electric oven, heat pump water heater and heat pump air conditioner/furnace. The place we were renting was about 3 blocks away. It had an old but not terribly old gas furnace, standard gas range and oven, gas water heater, and no air conditioner. It turned out to be a really great way to compare the two setups. One mostly gas, somewhat inefficient (which is standard out there), the other ultra modern power saving equipment throughout the house. The rented place had baseboard heating as well, but that is so wildly inefficient that we turned them off and never used them. Sweet jesus it was like lighting cash on fire.

My last bill gas + electric at the old place was $210. My first full month bill at the new place was $90, and that includes an AC running at the new place that didn't exist at the old place.

It is a shocking level of savings, and we aren't even in winter yet where my gas bills at the inefficient place would regularly hit $200.
