I used to be in in favour of nuclear. Nuclear works if you can guarantee political stability for 100+ years, but here in South Africa we can't even keep our coal plants running, nevermind guarantee political stability for 28 years (last year in June we suffered riots).

The risk of nuclear fallout is still relatively "localised", however that risk is dwarfed by the cost of disrupting centralised power production. A few nuclear plants are easy targets in the event of a war.

Distributed solar and concentrated solar w/molten salt seem like good options.
