Guitman, Norman_Thomas, and jospal217 make IMO important observations.
The nation of Denmark tried plunging into offshore wind technology and then their nation grew quite wealthy.
I’m guessing they did so, cause they were among the first. Other nations imported their tech?
World War II scale is about correct. But the more you’re concerned about those farthest in the future…the more World War II scale is not enough. The whole thing is up to us. Either transition remaining somewhat fat now, or, AFAICS, become way more ascetic for the sake of those in the far future. But according to Gail Tverberg’s article at Naked Capitalism 1/31/19 even radical asceticism now may not change the far future much at all. She doesn’t say that, but, going on what she does say, I don’t see how we could do anything now that would affect the far far future (maybe some means will materialize to do so, but doubting such a “maybe” IMO is the better part of wisdom). After listening to one of Tverberg’s 2015 youtubes, I’d say this is where Warren comes in (and Lori Wallach too). The financial picture, if left more alone than oil, will it seems cause oil to morph into the problem we’re anticipating [we could blow each other up over access to oil-in-the-ground, which could be precipitated by a financial crisis…not just precipitated by a grab motive alone, or a peak oil situation alone]. The global economy is the third element. It has to change. Buying so many products and shipping so many products seems to me has to slow WAY down. The degree to which this must take place has not as of yet been conceived. It’ll make Cuba’s “special period” look like Disney Land. But, IMO, it’s worth it for the sake of our descendants
It’s as weird as this, people…
“The problem, though, is that if more stringent EROI requirements are put into effect, wind and solar can be expected to do much less well in EROI calculations. They very likely drop below the threshold of being useful to the economy as energy producers. This is especially the case if they are added to the economy in great numbers to try to significantly replace fossil fuels.”
“Regardless of their value as energy producers, there might still be a reason for building wind and solar. Building them probably does help the economy in the same sense that building unneeded roads and apartment buildings does. In theory, all of these things might someday be somewhat useful. They are helpful now in that they add jobs. Also, the building of wind and solar devices adds ‘demand,’ which helps keep the price of coal in China high enough to encourage additional extraction. But in terms of truly keeping the world economy operating over the long haul, or in terms of scaling up to the quantity of energy supply that is really needed to operate the economy, wind and solar do very little.” https://www.nakedcapitalism.com/2019/01/peak-oil-story-close-not-quite-right.html
