All the battery powered stuff is cool. I own many battery powered things.
No one is mentioning the elephant in the corner. All these lithium batteries will soon be dying of old age, they only have a 7ish year life span at best and only if treated properly which almost no one does or even knows how to do.. They are extremely toxic and worse for the environment than all the fuel they saved over their lifetime. And the electricity to charge them has its own environmental foot print. Most of the electric in the USA comes from burning coal.So your batteries are still pumping out greenhouse gasses as well as being a toxic mess down the road. The lithium batteries must be recycled but many maybe most will still find their way to a landfill to reek their toxic effects on the environment. I have not seen a good comparison of the full environmental impact of electric vs fuel over the full life cycle of both.
Nearly every metal and chemical involved in lithium battery manufacturing creates health hazards, and some are toxic at every step.
