Nuclear is slow to operate, so it needs batteries to handle peaks during day. Nuclear can provide baseline power only.

Solar panel can be installed at roofs, so it can double as shelter, and power loss due to transmission can be lowered. Backup gravitational battery can provide backup power on site for short (hours) periods of time, to cheaply offset energy from peak of production at noun to peak of consuming at evening. Efficiency of solar panels can be improved up to 80%, so they can reduce need for air cooling.
