Very good, I appreciate that. That's good insight on the lifetime oversight.
Getting to the electrical folks, both groups have mentioned that there are very few GHG emissions. You'd probably be forgiven for not factoring in two other things. First is the GHGs created when you actually make the concrete that goes into the dams, and second, as we've learned from some of the assessments of the Site C project in B.C., is the methane that's produced when you flood an area. With that, plus what we've seen now, especially in British Columbia, with more of a turnover to run-of-river projects and then the stuff Elon Musk is up to with his electricity-producing shingles, do you think the era of the big dam is going to come to an end anytime soon? Very clearly, there are significant habitat implications when you build one of these things.
