Climate change solutions

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 can't scale up

• EVs with cobalt-based lithium-ion batteries
• EVs with platinum-based fuel cells
• Conventional (mineral-intensive) solar panels

Things that won't help

So-called "solutions" that would actually be counterproductive

• Geoengineering
• Carbon capture
• Trying to scale up conventional nuclear power instead of breeder reactors
• Trying to scale up biofuels
• Vertical farms

For any of these, read the page to see why they aren't helpful.

Things that might help someday if we're lucky

• Nuclear fusion
