Do power saving recommendations given out here to reduce consumption such as "don't use the oven" help in the winter given that wasted electricity ends up as heat? Or is this given by the electricity company hoping that they have natural gas to heat their house with instead?
If you have GAS you should use the oven and furnace as much as you can and shut off electricity. If you have electric heat it doesn’t really matter either way.
(Pro tip - if you have a gas or propane oven but a electric furnace/baseboard now is a great time to run the self cleaning cycle. The oven will get to 500+ degrees and heat your kitchen up real nice.)
Beside natural gas, heat pumps have become popular. Ballpack a heat pump at about 1/3rd as much electricity for a given amount of heat, compared to a resistive heater. Even (larger capacity) hot water heaters come with heat pumps now.
