Future generations will judge whether we did the right thing. They may not have the same opportunities as we do - once the damage is done - it's done.
Lots of interesting material there, and I am glad to see it agrees with many of themes of discussion that have arisen here (100% renewable future, shift to electricity, larger grids, energy storage as chemical energy from electrolysis, etc.) It also adds some themes that have hardly come up (demand management is a less sexy idea that can help a lot,. like energy efficiency can).
