Climate change solutions
If you'd like to see something added to this list, leave a comment on the talk page.
Biggest potential
- Thorium power
- Rooftop solar power using low-mineral solar panels, with sodium-ion or iron redox flow batteries for energy storage
- Scale up wind power and use the surplus electricity to produce hydrogen gas
- Hydrogen combustion vehicles
- Electric vehicles with sodium-ion batteries
- Reduce energy demand
Limited potential
- New hydropower projects - only suitable in a small percent of geographic regions.
- Rewilding - won't do a lot for climate change, but will work wonders to stop habitat loss.
Things that won't help
So-called "solutions" that would actually be counterproductive
- Geoengineering
- Carbon capture
- Vertical farms
- Trying to scale up biofuels
- Trying to scale up conventional nuclear power instead of breeder reactors
- Trying to scale up conventional mineral-intensive solar panels
- EVs with cobalt-based lithium-ion batteries
- EVs with platinum-based fuel cells
