Free market blah blah blah...

Someone needs to write a new script, if only the writer's guild were not on strike.

A real distributed renewable grid!  Using biogas backup.  Now try a solid oxide fuel cell/turbine with cogenerated waste heat used for heating.  That runs on biogas or natural gas as an ultimate safety backup.

I bet it's controlled with distributed computing.  All the computers controlling each source and load one big distributed computer.

Particularly when you include pumped hydro storage in the mix, maintaining a supply of renewable power that matches the minute-by-minute demand becomes feasible. With any luck, this undertaking will successfully highlight the possibility of moving to a climate-neutral and sustainable system of electricity generation at national scales and above.

I really like the idea of restoring wetlands to be used as pumped hydro storage.  Wetland areas along existing hydro dammed rivers could be restored by pumping flood waters back up the water shed using wind powered pumps.

That way dammed river systems would have extra hydro power capacity, flood waters would be conserved and purified, and aquifers refilled.

Furthermore, wetlands are huge carbon sinks.  

Low profile energy systems (to avoid impeding wildlife or river navigation) could be added along side gates in the river (to let water in and out of wetlands)that access wetland water storage and along areas where rivers have been lined with docks and/or concrete channels already.  Keeping natural river areas wild.

The Original Post wrote: Wind turbines and solar modules help generate electricity in accordance with how much wind and sun is available.

This would work fine if their variability were random enough. However, the reality is that their variability is very unrandom.

Straw man. Nothing has ever prevented 100% solar power of society -- other than cost and the solar-flux limit.

I'm wooed.

My only question is this: are there no mega-money, industrial entrenched interests in Germany to stop this?
