Pay for how hard you fight, unless you win, then it's free

Did you know? When you pay for electricity, you pay for how hard you push against it, until you win, then it's free.

In case it's not obvious:

If you have a device that has a lot of resistance (needs a lot of wattage/voltage/amps) you pay MORE than a device that has low resistance (low wattage/voltage/amps). So with an old fashioned 100watt lightbulb you pay for 100watt hours per hour of operation. A 4watt modern light bulb only costs 4% of that for the same number of hours because it ONLY pushes 4watt/hours per hour. A 4000watt 440V plastic extruding device pushes even HARDER and costs about 1000x's per hour what the 4watt lightbulb costs.
BUT ... now push SO hard that NO electricity flows, that is, turn the switch off - which really is "make a BIG gap in the wire that the electricity isn't strong enough to break - and now it's free! Of course if you push THAT hard - nothing gets done either, but that's irrelevant to the facts.

But they charge you to effectively do nothing

Similarly ... did you know that you don't actually buy the electrons that are flowing? With AC power the power company charges you to push them about 0.4mm in one direction, and then they charge you the same amount to pull them back 0.4mm; this is assuming you have 60 cycle power like we have here, if you have 50, it will be a little less. So power companies charge you for the electron moving in one direction, and then they move the same electron back to where is started and charge you to move it back. So electric companies charge you to do NOTHING on average.
