  • What foods do we eat Vs make into fuel? Hint, they’re not the same. Sorry, there’s plenty of info on all of this out there you just need to actually look with an open mind. I’ve given you the resources to start but I don’t have the time nor inclination to continually fight these fights with people who make clearly outlandish claims and then just come back with “well prove it”.

    I hope you do follow the links and go and learn more but ultimately that’s up to you.

    Enjoy your day.




  • 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?

    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.

    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.


  • Biofuels are even less efficient than making hydrogen for a fuel cell. It’s the same as growing cattle for a burger. It’s way less efficient an energy source because you have to grow up to 10 x more feed for the cow than you get out of the burger. You’re better using that land to grow the actual food for you. Same for biofuel. You get relatively little out for the shit tonne of land you need. Still use chemicals which all need energy to make and transport and use. Then you’ve got to cut, transport, process, refine, transport and then use the fuel. Much better to use the land for food or hell, just leave it to be wild and soak up carbon. Then all that energy you were going to use to make the bio fuel, stick it in a battery.


  • What the hell are you doing that you need to replace the battery enough for it to be classed as a weakness for all EVs??

    Look up Lithium Iron phosphate batteries. They will outlive the car they’re in even better than the lithium ion ones that are the majority at the moment. Those lithium ion batteries will also outlive the vehicle they’re in btw. The only ones that won’t are Leaf batteries because either they’re an old chemistry or because nissan cheaper out and didn’t put a coolant loop in them.

    Do the sums for a petrol car and then do the for any EV. Spoilers EV is always lower. And a EV only gets cleaner but an Ice still burns oil in some fashion for the rest of its life and burns it worse. I swear Americans are quite possibly the worst and most tribalistic people on lemmy
