Ask HN: What solutions would you like to see in the climate/energy space?

I'm trying to think of ideas to work on and crowdsourcing ideas to HN seemed like a viable option. So, what are some of the ideas and solutions you would like to see implemented in the climate and/or energy space?

I’m not pushy with this topic but as a species we could farm and consume much less animal meat. Not sure if that’s inline with what youre looking for but it would have an impact.

I'd create some tool that calculates your carbon footprint based e.g. on the size of your YouTube/TikTok videos or Instagram photos. Let's make everyone aware that the only way to fight the climate change is to change our behavior.
