The article doesn't give current or near-term percentages, but they have lots of current initiatives and results with wind and solar. They also mention methane from landfills, which I don't exactly think of as a "renewable". But I agree, setting an objective over 30 years away seems like an extreme case of "under promise".2050 is a long time. Why not do it now? At least go to 50% by the end of 2018 is highly doable with today's technologies that are affordable and can easily pay-off.
