- Comment on The World Has a Serious Coal Problem 1 month ago:
I don’t doubt that the return on investment for solar and wind will continue to improve relative to fossil fuels when used for electricity generation, but the problem seems to be, again, the manufacture of infrastructure such as wind turbines, photovoltaic panels, and so on, which require energy-intensive mining and refining of minerals. Unless every stage of the manufacturing process can be electrified, the efficiency of generating electricity using wind and solar won’t matter in the slightest, as there will be no way to use that electricity to eventually recycle/replace the existing wind/solar infrastructure, let alone to deploy more of it or to do either of these while maintaining the high energy return on energy invested.
To be clear, I don’t want solar/wind/etc to be dependent on fossil fuels at all, and so I would be interested to read an explanation of how these (or other) clean energy technologies can be deployed without using fossil fuels at any stage of the process. The problem presented in the article seems to be that such technologies currently do depend upon the use of coal, and I posted the article here with the idea that it might get people to start thinking about potential solutions to this problem, not to suggest that the deployment of clean energy technologies is not worthwhile.
Realistically, even if photovoltaic panels and wind turbines can be recycled 100% efficiently, the supply of energy from these sources at any given time will still have an upper limit based on the finite supply of the minerals required for these technologies, so people cannot continue to increase their energy consumption indefinitely even from “renewable” sources. But that’s a separate problem.

Do you know of a way to efficiently produce the infrastructure needed for solar, wind, etc using energy from solar, wind, etc such that the energy return on energy (ERoE) is high enough? That seemed like the crux of the argument made in the article, and I’d be interested to read a rebuttal.

It would seem that scaling back the use of many modern technologies is both necessary and inevitable. When hydrocarbon-based energy sources run out, it’s back to old-fashioned carbohydrates…

- Comment on Analysis casts doubt on ancient drying of northern Africa's climate, raising new questions about early human evolution 2 months ago:
If the history books are accurate, northern Africa in the time of Alexander the Great was forested. By the end of the Roman Empire, the forest had been felled to make space for grasses (both cereal crops and pasture land), and desertification ensued.
