Summary
If each person had a 12kW PV system, we displace all energy use including transport and industry.
- This easily fits on existing rooftops pending 6x efficiency, easily obtained by lifetime, modular design. And solar drones for transportation.
- Note this is for total energy, not just home energy.
Global Energy Production
- 170M GWhr = 21MWhr/person. This is the same as produced by a 12kW solar system! (26MWhr)
- 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. There is 1/5 the homes than the number people. Thus, we need 6x the homes to provide all energy. This is consistent with a home powering itself, and total energy use being several factors higher due to other human activity.
- 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 sise 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 for the electric portion only. But note that this is just a gap of replacing housing stock - only a percent or so is replaced annually.
- 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
- Note that there is a 6x gap in require rooftops area, counting only 1000 sf per house.
- 10x it from lifetime design
- 10x from modular design and solar drones for transportation
- 2x from more solar, 2000 sf total (practical)
- Left with 30x excess. But, note that the home-only perspective, 12kW system is sufficient for all needs. The 30x gap displaces industry.
- - implication: 30x the population, eco-industry in communities, and we are thriving with no visible degradation while regenerating people and planet.
