He's talking about installing solar devices to collect heat at the place of business/home and use it there. On-site creation (if you consider using sunlight creation) and consumption.
There is nothing stopping the creation of electricity/gas/etc and transporting that over long distances... while ALSO using solar devices at the business/home.
Why use electricity to heat water, when you can use the sun? Why run an electric heater when you can use the sun to provide some/all of the heat needed?
It's a great idea and he makes a lot of good points. If the engineering can be simplified and brought to the masses
