batteries are made out of nasty things...."do not dispose of.."
I also imagine they take lots of energy to produce....therefore their high cost
to my mind just because there are no exhaust
fumes immediately in my wake.....doesn't mean there aren't environmental repercussions. at the moment they are just "invisible" to the user.
I'm not yet buying
the environmental aspect.

So, maybe the way to go is to use better/newer diesel
Lithium mining does create some pollution, and I'm sure there are some emissions from the battery
power manufacturing process. But, those batteries can and do get recycled. Solar panels
from the 70s and 80s are still working, but most of those materials could get recycled too (glass and aluminum
, along with a little silicon)
But those one-time emissions pale in comparison to the machinery needed to drill for oil
constantly, the ships used to transport the oil
, the pipelines that have to be produced, the workers that have to be moved around to maintain, build, and repair all of this, the refineries that have to get built, the energy used to refine the oil into diesel, the chemicals that have to be produced for fracking or tar sand oil refining, the cleanup when oil spills happen, trucking gas and diesel to the gas stations, even the pumps and filling stations use energy, the production of the diesel motors and proper working emissions control parts
. The list is far bigger and I probably missed some.
And not to mention the amount of security
we provide and weapons we have to sell to certain countries to ensure that the oil keeps flowing.
