The point of storing anything is to be able to retrieve it whenever you want. Electricity can be accessed from nearly anywhere.You cant really store electricity or not efficiently anyway. That kinda ruins the whole idea doesnt it.
I back up my IOU with my word, and I have never failed to pay. As matter of fact, I am so trusted people use my IOU's to pay their own bills and they are accepted all over the world.
The government......determines an allowable range for free-market electricity prices
http://www.investopedia.com/terms/f/freemarket.aspDEFINITION OF 'FREE MARKET'
A market economy based on supply and demand with little or no government control.
Now, I mean that if the free-market price goes out of range, it buys and sells electricity futures, modifies capital and reserve requirements, buys and sells Treasury bonds, etc, to inflate or deflate the money supply so the price goes back in range.uhhhhh.....Did you just try to redefine free-market?

So are the others. But it's not really cost we need to be concerned about, but ERoEI.I am related to someone big in the energy biz. I will refer to him rather than wikipedia. nuclear is the cheapest. natural gas prices are variable. happy holidays.
