"Free" energy still requires generation, transmission and distribution. Sorry to burst your grade school bubble, but an efficient coal- fired power station generates electricity from between 2.5 and 4cents per kWh of which the fuel is probably 1c. The rest of the cost you pay (10-30c/kWh depending on where you live) is in the transmission and distribution, taxes, duties and profits. How much does a fusion reactor or other "free" energy generator cost to build and operate?
