Tesla literally has a massive (electrical) energy storage business alongside solar. There are huge battery installations that are helping regions like Hawaii and Australia pivot to renewables.

Transport is the 2nd sector in terms of CO2 emissions. If we solve that alone, I am happy.

Actually it's only 16% https://www.visualcapitalist.com/a-global-breakdown-of-green...

That visual shows that road transport is 11% , making it the second highest category, as the poster said. This is a great graphic though, thanks for sharing!

Edit: actually in the graphic it's the largest sector! My bad

I found it here: https://ourworldindata.org/emissions-by-sector

Not sure how reliable all this is... Yet it seems "road" is nearly 10-11% which is big enough to solve and to have already an impact in everyday life. Then it cascades to other sectors too.
