A few large-scale ideas here:
and for the truly small-scale:
Technology's running off in more directions than there are dimensions
(slight hyperbole there). To pretend that anything is proven to be
"impossible" shows ignorance and arrogance (or perhaps a vested interest).

On that, there's the Weißbach paper
(to which I don't have access) referenced in a post on Barry Brook's
To which my only comment is that the figures are comically rubbery:
Most of the "debate" about renewables and storage seems to centre around
the nuclear power lobby.
To get this a bit more on topic for Link, I reckon much of the solution
lies in demand management, "smart grids" and other efficiencies.
