Add water to that - at least where it's available, such as in
Switzerland. I could also see technology exploiting the tides as a
source for base energy.

Actually, a lot of the necessary technology is already there. In
industrial production, a LOT of energy is wasted with inefficient motor
drives (or rather: the lack of any drives): Those motors are either on
or off, the output power is regulated using brakes. Using semi-conductor
based drives can often reduce power consumption by 30% or more.
Considering that something like a paper mill might have several 50MW
motors, it's obvious that optimizations there will return a lot more
than even the largest cities switching to "energy saving" lightbulbs...

I only agree partly here. Technology is good, but not just on the supply
side. One area where we really have to reconsider our way if life is
mobility. We're using way too much energy there.
