Didn’t the 2009 Recovery Act that Obama spearheaded also have a heavily invest in renewables? [1] Over 10 years it averaged to about 9 billion per year. I seem to recall that this investment push was twofold: investment in American renewable tech and rebates to spur demand. China heavily cut solar prices to undercut those solar investments (leading to Solyndra’s bankruptcy) but that had the effect of lowering prices further spurring demand worldwide.

I don’t have a sense of Germany’s impact in this space as I haven’t kept abreast of their investment nor about the specifics of renewable investments more broadly.
