Nuclear is: very slow to make, very expensive, generates dangerous waste, invites proliferation.

Wind and solar are quick, relatively much cheaper, create little waste. The sun is forever.

Personal transportation needs a complete redesign. Burning fossil fuel at 20% efficiency (80% waste) to push a 4000lb. vehicle with a 200lb person in it is insane. Personal electric vehicles of 200-300 lbs tracking defined lanes at 20mph under computer control would take care of 80-90% of urban travel needs. And greatly reduce the number of roads needed.
