It's really the customers who are happy to pay that. And no one who's buying a calculator is thinking about how much per kWh they're paying, it's more a "convenience" feature of not having to change those little button cell batteries that the local drug stores gets $5/pair for (...which is... let's see... assuming alakaline LR44 cells... 150mAh*3V = 450mWh or 450e-6kWh --> $5/450e-6kWh = $11,111 PER KILOWATT HOUR! OH MY GOD IT'S THE END OF THE WORLD! :-) ) People who are heating water or their homes or running motors or furnaces or air conditioners are the ones who start worrying about the cost of a kWh... I like your presentation, though -- it makes a lot of good points, although I do think you need to place more emphasis on how here "in the real world" there's a lot more that goes into energy decisions than just efficiency and the direct costs: Where does the pollution go? What are the indirect costs? Does it look attractive (it's amazing how many people object to having, e.g., an oil refinery in their town primary because it's ugly and smelly)? Etc... Consider how much energy was wasted building the pyramids, and how much more is today as people fly from all around the world to see them. :-) ---Joel

And worse yet, the government largely subsidizes this means of food production! :-) ---Joel (off to eat some beef...)
