Fossil fuels are a much bigger problem than the materials for batteries. Also the metals are recyclable and the batteries are evolving, getting better.Nether one is sustainable, the metals needed are finite. Fossil fuels are finite. I don't know what the answer is, but I couldn't do solar or battery until they can recycle, otherwise it's just more toxic trash at a higher pace then with combustion engine vehicles, etc.
If you leave the stump to rot it’s better for the environment and it cost you nothing.the remaining stump and burn it out over time instead of renting a stump grinder for something like $150 for one day use.
Its not about long term. Climate catastrophes are happening already. Did you forget the extreme temps you had in Canada. The ongoing fires in Australia. The increasing force and numbers of hurricanes in the US and the Caribbean, the extreme floods in Bangladesh, Europe and Mozambique. The Islands Tuvalu and Vanuatu who are disappearing into the sea.Cost of generating electricity is the driving force. Lots of people are not so concerned about the long-term future costs of how we make our electricity. It's not even a consideration for sustainability, either...
And even if we stop using fossils fuels today, and do nothing else the global warming and temp rise goes on for over a decade.
So…Please do not talk about the long term, but about now and today!
