I don't have the same take away as Lucas, but I understand his sentiment; it would be helpful for him and other like minded to gain an understanding of impermanence though.
It was reported recently, in Bloomberg News, that in Texas, there was one day in Feb 2016, that half of the energy consumed in the entire state came from renewable sources. The state of Nevada, in 2016, granted huge tax credits to Tesla and SolarCity for the largest battery research and development facility in the US, that will lead to the creation of thousands of good paying jobs for Nevadans; the legislature now require electrical utilities to purchase excess capacity which is a move designed to move away from coal and natural gas towards renewable sources to energize homes and businesses.
The world is a different place than it was during the 70's and we should be thinking about going forward instead of backwards.
