I have no idea how you possibly came up with this.
For a start, there are a ton of non-energy uses of fossil fuels (eg fertilizer, plastics, roads). There are certain vehicles with huge impediments to switching away (eg planes, ships).
And beyond all that there are a ton of other sources of greenhouse gases, notably construction, specifically concrete.
We’ve taken a ton of sequestered carbon from the ground. To get net zero we’d have to sequester at least this much and the real way we have is growing plants. There are only so many plants you can grow.
So how do you get to get net zero?
- jaggederest 8mo agoMy hyperbolic suggestion was to build four pyramids of carbon cubes. They'd have to be about 5km wide and similarly tall, and would be by far the largest structures ever built by humanity. You'd need supplemental oxygen to spend any substantial time on the peak. Assuming we had too-cheap-to-meter fusion or a dyson swarm or something like that, of course. Call it total cost of say, $50 trillion, no big deal, right?
