This is why my mom is switching from oil to electric for her furnace... power here is pretty cheap, and it will be cheaper to run than oil (plus replaced the current furnace and 47 year old underground tank) as long as it remains at this prices which I doubt it will ever go under $3.00 per gallon ever again.
A heat pump would be nice (especially for the A/C) but just not in any budget to do the full install of one.
