He should even explain more about the microgird. How will the electricity is going to be generated? Let us say that in the setup there are batteries, batteries are very costly and the batteries capacity can reduce over time as it ages. How will the electricity be generated? Through solar, wind or what? Which means microgrid is not only about batteries, there are other things like turbine or solar panel need to generate it. There are many ways that miners are generating electricity now, but I will not advice anything that requires battery which is costly and the battery capacity reduces as time goes.
