In my position as overseer of electricity production, I'd use three main components:
• Vertical axis wind turbines (VAWTs).
• Sodium-ion batteries (aka molten salt batteries).
- Six vertical wind turbine power stations with three hundred turbines each & accompanying molten salt battery facilities in Mkhanyakude District.
- Five vertical wind turbine power stations with three hundred turbines each in eThekwini Municipality with molten salt battery capacity.
- Solar power station in Majuba District with 2500 MW power generation capacity.
- Solar power station in eastern Ekurhuleni with 3500 MW power generation with molten salt battery facilities.
- Three vertical wind turbine power stations with three hundred turbines each by Umgungundlovu with molten salt battery facilities.
- Five vertical wind turbine power stations with three hundred turbines each & molten salt battery facilities in the Ugu District coast.
- If we make streetlamps & streetlights (robots) individual solar powered units, we'd solve half the lighting problem.
- Hospitals, police stations, home affairs offices & other vital national buildings need to be self-sufficient in wind or solar depending on which would be optimal for the region.
I'm not sure of how many wind power stations or solar panels we'd need for each power station but each station should have power-generating capacity of between 3000 MW to 5000 MW.
The positioning of these renewable energy power stations would be based one the regional power potential for solar & wind power.
