I cannot be energy sovereign with a nuclear power plant.

The huge centrally planned hydro and nuclear power plants are a great way to keep a population dependent on the entity on control of the grid.

Perhaps in some future with small scale village-size solutions, but we're not there for a long time.

I do however generate more solar electricity than I consume in a year.

In Sweden which is dark in the winter, we need to keep the grid running with hydro and fission.

A small scale Stirling or steam powered CHP device might work, but the only alternative I can see in winter is a ~20 kWh battery and diesel genset.

Solar panels are fusion siphoning devices and they are a fantastic complement that increase my sovereignity and grid dependency.

Their energy ROI is about 5-10 years I suppose.

Fission is fantastic if you're comparing to huge wind farm, but not good for small scale sovereign individuals.
