Global Energy Production

170M GWhr
- 22k TWhr in electricity production
Let's take the total, and put it on solar roofs.
Our house has 12kW each. That is 26MWhr per year, or 0.03 GWhr annual
This is 5.6B homes. That is more homes than exists today.
If we take just the electric production, then we have 700M rooftops.
Each Campus produces 500 homes per year. 1M homes means we would have 2000 Campuses in the USA. Market size is large for the USA alone. And a global market about 4x this [1]. Thus, 8000 Campuses worldwide. But. That is still only 4M rooftops, 200x less than what is needed.
Installed powerplants are 60k of them and 6TW total installed.
