3) Environmental impact of disposing of EV batteries are largely unknown. (Though more likely to be directly effecting humans through exposure to toxins etc. than effecting climate through emissions.)
4) Hybrids are only effective at reducing emissions if driven "appropriately". .....
- Li from EV will be reused in Solar System around New Zealand... Just make sure after it completely used up - to deplete leftover charge before disposal not to create fire hazards;
- Hybrids are very effective - no fumes when you start or park your car and usage is 3.6 -5.6L/100 km (do not listen to Clarkson, he is not driving hybrid, my hybrid uses 4.1l/100km)
As for disposing EV of Hybrid batteries - if you have failed one - I can help you to put it into good use, give it second life...
