Germany's promotion of renewable energy rightly gets singled out for its effectiveness, most often by me as an example of how to do things well versus the fits and starts method of promotion common in the US. Over at Wind-Works, Paul Gipe points out another interesting facet of the German renewable energy saga: 51% of all renewable energy in Germany is owned by individual citizens or farms, totaling $100 billion worth of private investment in clean energy.
Breaking that down into solar power and wind power, 50% of Germany's solar PV is owned by individuals and farms, while 54% of its wind power is held by the same groups.In total there's roughly 17 GW of solar PV installed in Germany—versus roughly 3.6 GW in the US (based on SEIA's figures for new installations though the third quarter of 2011 plus the 2.6 GW installed going into the year).
Remember, Germany now produces slightly over 20% of all its electricity from renewable sources.
The thing that got me though, other than the huge lead in solar PV installations Germany has over the US, thanks to good policy, and the fact that so much wind power isn't owned by utilities, is what slightly over half of renewable energy being owned not by corporations but by actual biological people means—obviously a democratic shift in control of resources and a break from the way electricity and energy has been produced over the past century.
A good thing: Decentralized power generation, more relocalization and reregionalization of economic activity, the world getting smaller while more connected and therefore in a way bigger at the same time... taking a step backwards, and perhaps sideways, while moving forwards.
