Here's what happens when your Tesla Roadster (or any EV) reaches the end of battery life

There is no easy answer. Alaska's shoreline is still polluted from the Exxon Valdez oil spill. The Gulf of Mexico shoreline was cleaned somewhat by the hurricanes, but the oil went somewhere? The Keystone Pipeline dumped 600,000 gallons of toxic chemicals and bitumen into the streams and land of Kansas. Oil filters and used oil get burned and dumped into the air that we breathe. And don't forget the 10 million or more nasty lead-acid batteries that get recycled every year.

Most EV's go 200 too 300 miles [about 3 hours of driving]. By then I need a break, and sometimes longer than 15 or 20 minutes. And maybe a nap, too.

Sodium ion batteries are here now. Tesla is putting them in some of their cars .
