Right, let's start with old oil. How much do you think is generated world wide? It's about 1/20th of the amount of oil we use currently and that created not recycled so that number is far lower so really that's a niche. Likewise wood pellets. Unless you're actively chopping trees down to make into pellets you're not going to have any real volume there. Plus as I said previously, all of that takes energy to be made into usable fuel. Where does that energy come from and also why not just use that energy directly?
5% of our current oil demand is still a big improvement. That's probably enough to move a significant portion or even all of aviation to sustainable fuels. Aviation is one of the places where batteries don't work yet, and probably not anytime soon either.
As for the last paragraph, no, sorry you're just misunderstanding that whole arena. Batteries are more than 90% recyclable and that number is going up as we design them to be easier to recycle. Plus that's most likely 20 years from now on average. As for solar panels they're aluminium (easily recycled) glass (easily recycled) metals (easily recycled) and silicon (mostly recyclable) and again they're being designed to be recycled better than they were. Ontop of that they now last up to 40 years with greater than 90% of their original capacity left so basically they'll outlive most of us on here.
Can you give me some evidence?
We've grown plants sustainable for thousands of years except for in the last 150 where we have systematically wrecked the ecology at the same time as massively increasing our population. The average westerner uses 32 times more resources than the average Kenyan. Do you want to have the same lifestyle as they have? Because they want what westerners have so that means we can't keep going as we are and have to change.
So you're saying sustainable agriculture is impossible? If so then climate change is inevitable and there is nothing we can do.
