i am not certain HOW they will do it, but They will do all they can from you getting it for free.   i have heard report in the USA of some off grid people getting told to shut down their operation because the the utility company was not making money off them and they we not complying.  Other people have been bought out or shut down.   Think of all the alternatives for gasoline.  Hell you can burn cooking oil from a restaurant as fuel.  That was silenced. Countless other types of energy for cars have been silences.   Solar and wind is no different.  If the Big utility corporations cannot make money off of you they will prevent you from it.  Countless other forms of energy historically were silenced by the big corporations and elites. It could be a big  Global climate change tax for which the monies go to the utility companies.   But history dictates that they will not let you enjoy it in large quantities without paying the big boys for he use.   History dictates that they want us as dependent as possible.   There are large movement  of folks fighting this through grass roots efforts of urban farming, hobby farms, self-sustaining efforts but it is a battle.   It will be intriguing to see how it all plays out. More intellectual intercourse to contemplate. Again thanks.
