What?
Do you have any idea how many things we can do with basically free energy? Like for instance, desalinate and clean sea water and pump it back into our exhausted aquifers. Or scrub carbon from the atmosphere with gigantic manual filter aways. Or just store excess power in grid scale batteries and cycle plants on and off as needed.

To my knowledge, electric energy generated by heated water is not producing any kind of effect comparable to nitrogen dumped into a lake or CO2 into the atmosphere. If there’s some source suggesting otherwise, I’d be curious to read it.
I think you’re confusing fossil fuels with fossil fertilizers. And eutrophication just isn’t a major concern in a planet that’s losing biodiversity and biomass to excess heat.

You’re not understanding my analogy.
Eutrophication is the addition of too much food for one type of living thing in an environment, allowing it’s population to grow too large for the ecosystem to support. This is exactly what the Green Revolution was for humanity.
I’m talking about fossil energy in general, all forms of it. Fossil fertilizers are one form of fossil energy.

I haven’t seen any evidence of this. At best, you could argue its been wheat, rice, and corn undergoing eutrophication. Perhaps cattle. But outside a few exceptionally well-fed western enclaves, we’re operating below the standard intake of our hunter-gatherer predecessors. Blame our sedentary lifestyle or our aging population, but most humans consume below the 2750-3000 calorie diet of our ancestors.
Then you’re talking more on the industrial scale than the physical. And that’s got far more to do with our tolerance for waste than our appetite for raw inputs. For basic needs like light and heat and travel, we’re significantly more efficient thanks to a host of modernizations like insulation and mass transit.

Still not quite getting my analogy. I’m not merely speaking of calories, or how we decide to dispose of waste.
–> I’ve never seen anyone use this terminology before about “human eutrophication”, I made it up. But if you want more info on this topic, www.youtube.com/watch?v=mVjhb8Nu1Sk
The evidence is the apparent non-sustainable lifestyle that is only possible by the addition of energy not part of the natural short-term energy cycle of the planet. We are making species go extinct and destroying this planet.
By using fossil/nuclear energy we are able to produce enough food to quadruple the population this planet could sustain without that extra energy. All those extra people need more than food, and in producing all the other needs for this expanded population, we damage the ecosystem. The planet is not ours to use, we are
