Just how much undeveloped hydro potential do you figure for California?<p>The state&#x27;s not water-rich to start with.  Dams have significant impacts, and virtually all major waterways are already heavily managed.<p>Nuclear faces safety, fuel, and disposal challenges.  The latter for the nex million years.<p>Fuel availability is ~80 years at present usage, 6 if the world relied solely on uranium-based fission.<p>Systemic risks of nuclear are distinctly non-negligible, and are not technologically addressable:  they concern management, organisation, politics, war, economic stability, and far more.<p>Solar and wind fare far better on all counts.
