Been a little while since I looked up the utility rates, but last I remember gas is about 1/7 the cost of electricity in Saskatchewan. Makes it hard to justify heat pumps for heating in most places. Hope the technology continues to improve and it’ll be a more sustainable option when we have a more sustainable grid.
Gas furnaces achieve about 96-98% efficiency. Heat pumps achieve 300-400%. So you have to factor that in.
There's still a cost difference but the hope is for governments to start supporting serious nuclear energy to drive down electric costs. It'll take time but natural gas will become less economical as decades go on especially with investments.
How does something achieve 300-400% efficiency?
Refrigeration cycle can get crazy efficiencies like that because it is transferring energy from one side of the system (indoor unit) to the other (outdoor unit). The amount of energy that is transfered is greater than the amount of energy required to push the refrigerant through the system.
Newly built nuclear would do many things, but it wouldn't drive prices down.
Wind and solar would do that though.
Yeah, depends where you live. Saskatchewan is the worst place, Quebec is the best.
I'm in Manitoba and am kind of in the same situation. Even though our electricity is really cheap, it's still more economically efficient to use natural gas. Coupled with just buying a new furnace and air conditioner, I don't see myself getting one anytime soon. I'd still be happier if we subsidized electric heating/heat pumps (or stopped subsidizing fossil fuels so much) but recognize I'm in a place where I can afford that and many others simply can't.
I have to pay about $50 USD per month just for the luxury of having heating in the northern US., even during the summer when I don’t need it. R The gas company can fucking blow me, I’m getting natural gas out of my house as quickly as I can afford it.
Yep, doesn't make economical sense here yet. Better to put money towards air sealing and (the right kind of) insulation.
