Funny how rating other comments can resemble a WikiWalk. I saw this comment, which I thought was attached to this article but I can't locate it, which provided a link to a paper about some of the Catch 22s of alternative energy.

My thanks to whoever posted the link. As an engineer I recognized some of these problems, but did not have specifics or the data.
(Perhaps someone didn't like the contents😡)
