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 needed for 170M GWhr. 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 [2]. Typical area is 1 sq mile, so we have 60000 sq miles of power plants .
Each sq mi makes 700M kWhr, or 700 GWhr or 0.7 TWhr. 60,000 of these make 42,000TWhr
- All power plants converted to solar produce 2x the required global electricity, without addressing 'storage'.
- And this is 1/4 of total energy use by humans
