Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
The easiest solution would be to produce the power outside Germany, in places where the climatic/political conditions are more amenable to it, and then run HVDC lines.

Clean Options, alphabetical:

Advanced nuclear : Build molten salt reactors in the Czech republic, France. (these are two of the nations with the most actual, current, research into this)

Boring nuclear: Same, but with PWR's.

Renewable: Solar: Longer HVDC lines. Into north africa. Lots, and lots of solar. Mostly this gets you increased reliability and removes the "winter" problem.

Renewable: Wind: North sea floating windmills, produced shipyard style. Domestically, build http://eduard-heindl.de/energy-storage/energy-storage-system.html to level out supply.

Call me irrational and/or simple-minded, but after Fukushima, I am completely anti-nuclear.

At the top of your list, I would add two options:

  • reduction in consumption
  • efficiency (e.g. better insulation)

Passivhaus construction -- which is even spreading to China now -- is in line with these two.

Reductions in overall electricity consumption are not going to happen.
Cleaning up the rest of the economy - transport, chemical and industrial processes currently run of fossil inputs and so on means that the grid is going to have to supply a lot more juice. Currently electricity is roughly a third of our energy use, in a zero-emission economy, it will be well north of ninety, with the remainder being things like food production waste based fuels for niche applications and ambient heat sucked in by heat pumps. So even large efficiency gains still imply electricity production that is overall quite a lot higher than at present.
So production plans need to be scaled for that, and the main point of efficiency gains is to limit just how much additional cabling you are going to have to bury.

Some of the extra consumption isn't actually going to impact the last-mile grid too badly. If we go down the path of "all electric motoring, and all electric home-heating via heatpumps" (you cant do district heating off a windmill.) then that demand can all be time-shifted trivially, so existing wiring out to residences would need only modest upgrades. But the production side? That is going to need beefing up. A lot.

You're irrational and/or simple-minded.

Like me.
