Free energy just isn't going to happen.
It is much more intelligent to use in a first step energy more effective. It starts with transportation (a decent public transport system based on railways is here very helpful), goes further via insulation of houses (here in Britain some of the best insulted houses were build during the Tudor reign), the way to heath housing (electricity is here really a waste), and some clever concepts, which are not really new.
Such concepts exist since decades, build up on well tested and well known technology concepts of e.g. a heating pump running on a stationary diesel motor which does reuse the extra heat of the motor and does produce some extra electrical energy - nothing really new, build since decades, but so long energy is still relative cheap and people prefer to live in suburbs with their long distances (where you even can't buy some milk without using a car), such concepts will not come into reality.
