Default Dust down those orbital power plans

No, it means other than fossil or nuclear. So propapanda indeed.

There is no abscense of innovation in
renewable energy, I can assure you. PV grew by over 53% last year
alone, compared to the previous year (which had a 40ish % increase on
the previous year). Right smack-bang in the middle of a recession.


Following the expontential growth pattern of solar, with a best guess on
when it will roll over to an asymptote, suggests around 2030 for the
time it replaces nearly all peak load generation.

Have a look at what Germany are doing - getting rid of all nuclear power
stations before 2020. The shortfall in electricity will be made up with
improved efficiency at coal stations and also more RE.


Which gives them a decade of being short on electricity. No matter the
anti-nuke sentiment by the irrational masses the need is for safer nuke
not for less nuke.

There are already power stations in the U.S. and U.K. that run on poplar
and willow SRC (Short Rotation Coppice, I recommend looking that up).
Not experimental stuff either, but actuall grid-connected power stations.



The German nukes aren't closed down until the local capacity has been
supplanted by coal/RE.

Why do you say propagana?
