Excellent article, thank you for your hard work. I'm curious about your comment that electric is the cheapest heat energy source. I wondered if you have done some comparative number crunching (electric vs propane vs natural gas vs firewood vs whatever) to convince yourself. I don't have enough technical info or expertise to figure out how to do that (make some realistic calculations), so far. I'm about to upgrade my brewery size-wise, moving from electric stove boiling 3 to 4 gallons, to a big brew pot in which I'll be boiling probably 15 gallons plus. I just assumed I'd have to use a propane stove out on the porch. If electric would be cheaper, and if I can get a hold of some kind of immersible, powerful electric element maybe I should consider that. If you have any comments, please share.
thanks again for the article, cheers
