This is a really great idea but I think access to technologically advanced hardware is a stronger component than energy here.

Making open community chip fabs might change that.  Then anybody could get on the bandwagon.  But right now the hardware barrier keeps the common person out.

If you can build a chip fab, you may also be able to build a powerplant.  Not many others can do that to compete with you.  The energy economy still has more supply than competition or renewable energy would quickly outcompete nonrenewable as the price dropped.
