Renewables cost is going down thankfully as more is built, but we need to do something about the mining for metals for all the batteries. They have child labor and poverty wages and no safety and maybe even slave labor in some places. I read something about how crypto can be good for movements like organic and fair trade because you can literally track where all the resources come from on the blockchain, so maybe someone could build a blockchain tracking system to keep companies honest that they are treating miners well and fairly. Because some companies now are like "yes we signed up for this certification" but really no one inspects or if they do they announce it first so they know to send the child laborers away or something, and it isn't any better.
