I did some checking last night on this topic. What I learned was kind if eye opening.
Electric range top is approx 70% efficient at getting the heat from the source (burner) into the reciever (metal pan).
Propane, due to its requiring the pan to sit higher over top of the source, and not sitting squarely on the burner which allows heat to escape from the sides, is only 40% efficient at getting the heat burned (released into the area around the pan) into the pan. That means in the cooling season cooking on a stove top with propane requires the AC to pull those BTU's back out. Winter time, who cares about the inefficiency?
Induction stoves hit their target at about 90%, microwaves even higher.
On to the water heater. Electric is 100% efficient and some propane tankless are around 95%.
At 12 cents per kw, propane would need to be approx $3.60 per gallon to equal equivalent cost per btu produced. But current propane costs are about 2/3 of the $3.60 ($2.40) making it about 33% more cost effective to heat with propane currently.
One big surprise I found is the heat generation required to send you 1kw to your home. Heat required is about 10,000 btus or 3 times the energy you get from it on your end. Add in a 4% transmission line "leakage" (tree limbs, moisture in insulators, resistance in main line causing heat loss, and transformer loss) and that propane looks pretty green.
So if your goal was efficiency (save the planet) and performance, and you used alot of hot water and cooked every meal on your range or in the oven, is propane or electric the way to go?
I know this has little to do with religion, transgendered people or politics, but still thought we may get some interesting points in a debate.
