Electric heat pumps have resistive heating elements that come on when it's too cold for the heat pump to create heat.

Electric resistance heating is wildly expensive. The power company is burning coal. Using that to boil water. To turn a turbine. To generate electricity through mechanical motion capturing a percentage of that heat energy as electricity that they send to you that you consume in a controlled short circuit as heat. 2/3 of the heat energy is wasted as steam out of the stack. What a stupid way to heat.

Electricity is very useful. It can do a lot of cool things. Using it to create electric resistive heat is an incredibly stupidly inefficient use of it.

Burning oil should be a lot cheaper but it's not because. I forgot why. Something to do with sulfur maybe? I don't know. Dinosaur juice should be 2 dollar a gallon but it's not.

Idunno. I forgot what I was talking about.

You people with your three digit power bills. lol :mad:

Do you think it's an issue with having infrastructure in place that's too expensive to update? It feel like a bit of foresight could at least have set up a mechanism to use the 2 thirds of energy lost in this transaction toward something productive .

Florida must have known I was coming and shown mercy on me, as it was the coldest you guys have seen in a while. I was the retard in shorts and a t-shirt, while you all looked like Randy on the way to school in ‘A Christmas Story’.

So cold at home right now that Huck didn’t make it the length of the driveway before he was lifting a paw. He loves the cold, so this is saying something.

Like for the picture, but a 😕 for Huck’s paw.

Not much you can do on the generator side. Going from coal to electricity nowadays is very close to the thermodynamic optimum.

The heater in your house is a different question.
