One of the more interesting ideas for climate action is the idea of divesting in fossil fuels. If investing in fossil fuels stops or declines, fossil fuel industries will lose money and go out of business, and fewer fossil fuels will be burned. A number of groups and individuals have suggested this strategy.
This is actually an interesting idea because it represents something concrete that we can do. But how is this strategy supposed to work? If we are successful, what does this look like? The strategy seems straightforward enough: convince enough people, and enough banks, not to invest in fossil fuels, and presumably the oil and coal companies will go out of business. And then what? Divestiture is a good start and a tactic that we can grasp. But I would like to see just a bit more detail here.
Perhaps renewables will replace fossil fuels? Obviously this won’t happen right away. It takes fossil fuel energy to produce that renewable infrastructure, so we would have to continue fossil fuels for awhile until we are at 100% renewable energy. The fossil fuels will do two things during this transition phase: help build out a renewable infrastructure, and supply energy for the rest of the economy in the meantime.
Here’s the detail that’s missing: this means a MUCH smaller economy. Ultimately, this will mean an economy perhaps half the physical size of the current one, or even smaller. This may not be a popular move politically! We can ameliorate this situation by radically redistributing wealth, but that’s a second revolution—a social revolution—on top of the environmental revolution.
To go to 100% renewables for ALL energy and still provide our current level of energy use isn’t really possible. Point number 1, this requires a massive increase (fourfold or fivefold?) in the electric grid, since now most U. S. energy will be electrical energy, whereas energy consumption in the U. S. right now is about 80% from fossil fuels.
Point number 2, this also means electrifying transportation. This is a huge infrastructure investment. Electric cars are possible, but there are serious technical difficulties with electric trucks, because the batteries might have to be almost as big as the whole truck. Point number 3, you need huge quantities of energy storage for when the wind doesn’t blow and the sun doesn’t shine. Point number 4, electricity doesn’t work very well at providing the high temperatures for heavy industry like steel production. Point number 5, many renewables require “rare earth minerals” such as neodymium and dysprosium, which are in scarce supply, and also needed for information technology, as well as consumer devices such as cars, washing machines, and refrigerators. Point number 6, even if renewables work like a charm, because of sulfate aerosols they will temporarily make global warming worse.
And point number 7, why don’t we focus on reducing livestock agriculture instead of (or in addition to) switching to renewables? About half of the climate problem is due to livestock agriculture—reforestation and revegetation would draw down huge quantities of carbon.
Climate is not even half of our environmental problems! What about peak oil, biodiversity collapse, mass extinctions, soil erosion, groundwater depletion, emerging infectious diseases, and pollution? We’ve exceeded planetary boundaries on numerous points.
So, sure, by all means let’s have divestiture, but let’s be honest with each other, and the American public, about what this means. Divestiture is a good start; it’s a tactic that we can actually grasp and carry out. We need more. The economy needs to be smaller—a lot smaller. That’s what we need to be talking about.

*Perhaps you could elaborate again on what you mean by “the physical size” of the economy.
The physical size of economy is the total “throughput.” In Ecological Economics (2004), Daly and Farley define throughput as “the flow of natural resources from the environment, through the economy, and back to the environment as waste” (p. 6).
The idea is to identify economic growth as a physical phenomenon. We may, through technology and efficiency, be able to do the same thing with fewer materials or energy. E. g., a more efficient car engine, a faster computer, or a better constructed house, like the “passive house” which doesn’t require any energy to heat or cool. The economy can improve without its physical size necessarily increasing. Unfortunately, today it is the total physical size that is increasing, especially pollution (plastics, CO2, etc.).
I see. Thanks.
So did you see that latest IPCC report? Much of the damage is already “baked in” – pun intended – and yet they still think they can ignore animal agriculture as a factor in CC. They might have been able to work around it if massive progress had been made on renewable energy, but we are now beyond that point. They will ultimately have no choice but to acknowledge the need to eliminate animal agriculture!
I haven’t read the IPCC report itself, but I’ve seen news stories about the report. Yes, it’s grim. As I read the story in The Guardian, though, it seems that the IPCC report is still being written, and they haven’t yet addressed what to do about it, so there’s still a chance they might say something strong about livestock agriculture. “A third section, due in April, will cover ways to cut greenhouse gas emissions.”
This looks down our alley:
