It costs a lot to maintain the wasteful lifestyle to which we have
become accustomed if we remove ourselves from the "economy of scale"
that grid power introduces. Since said "economy of scale" is dependent
on cheap, plentiful sources for energy to convert to electricity at the
large scale which introduces said economy, and we all KNOW that can't
continue, maintaining said wasteful lifestyle is out of the question.
It is only a matter of if you learn to be energy efficient by choice now
or by force later. Those who chose to become efficient now will hardly
even notice when later gets here. That is your choice.
