Still the prognosis "not anytime soon" seems alright. Here in the Netherlands it turns out that:
1) while 69% of homes are paying for green electricity, only about 5% of the juice we get is actually green
2) when paying for green juice, we must pay 350% taxes and tarriffs (I do too)
3) we are importing ancient American forests with boats on "stookolie" (tar oil) and they are burnt to produce "green energy"
We too, are a long way from anything sane. I personally hope for increased efforts in clean nuclear like Thorium reactors and synthetic fuels. If we produce CxHy compounds, we could fuel our aviation and motor sectors with clean fuels.
