Thanks for the links.
I'm still confused though. Is the underlying assumption that the sun's energy being dumped on earth is essentially saturated? That is, "nature" has long since used all the available sun's energy and any energy we use from the sun is effectively taking away from nature?
Doing some back of the envelope calculations, we can estimate that the sun dumps around 700 peta watt hours per day whereas we use roughly on the order of 230 tera watt hours per day. Historically we've been increasing our energy consumption at about 2.5% per year which gives us a rough estimate of 250-350 years before we reach the limits of the available sunlight on earth. [0]
Daly's argument is that the 700 peta Wh/day minus the 230 tera Wh/day is maximally being used by "nature" and we would only be taking away that energy for our own use? If so, doesn't that seem a bit far fetched?
Also, natural resources might be limited on earth but are exist in abundance in space.
