Just got a link to this article with my monthly bill and thought it may be of interest here: Microwave, electric oven or slow cooker – Which uses the least energy?

Without clicking on the link I would say Microwave unless you were processing Gold which takes many hrs

That's fine as far as it goes, but it really only tells half of the story.  You also have to consider the consequence of the waste heat each appliance produces.

 

If it's summer and you're running the air conditioner, the microwave saves even more compared to the slow cooker or oven because it produces much less waste heat that the air conditioner then has to run longer to remove.

 

But if it's winter and you're paying to heat the RV (or house) that same waste heat can make running an oven or slow cooker essentially free - the heat they produce adds to the heat inside the house, which means the furnace runs just that much less.  Energy wise, it's close to a wash between heating the oven (and then the house) or running a furnace longer to do the same thing.

 

That's one of the big fallacies in the incandescent vs. compact fluorescent bulb debate.  You don't save any energy  in the winter, when lightbulbs are on longest, by replacing incandescent bulbs.   You only save money during the warmer months when the furnace is off or when you're air conditioning the house - and that's when the days are longest and you use lightbulbs less.
