Positioning for When Water Runs Out: Part II

The author wrote: "These folks are well-meaning but disappointingly misguided, given that the authors are mostly civil engineers. I am 110% in favor of using sun, wind, or tides, but our water problems are pressing now, not in 20 years. Couldn’t we just once plan ahead of a known catastrophe?!! What is available now is nuclear and natural gas, and dirty old coal and oil. You want water? Fess up to the reality that it takes energy, and the energy sources we hope to replace are still the energy sources which we have in abundance -- with a transportation and distribution infrastructure already in place."

Not paying attention to energy consumption and greenhouse gas emissions will prove costly in the end. While I agree with a portion of your post (Joseph), I'd strongly urge to rethink your position here. It is precisely this sort of thinking that has and will accelerate climate change.
