Elon Musk talked about how BTC mining with electricity isn't environment friendly but he invented electric cars, in near future if this actually becomes popular electric cars will be available world wide and billions of vehicles will be charged by electricity so how is this environment friendly?
I do not know if people here are joking or not but some of you have zero clue how the cars work right now as it seems. Right now we are using gas, petrol, basically oil, which is basically limited and requires us to kill the earth in order to get it, freaking and all other methods are making the world a horrible place to get out. So that means in order to get electricity from that, we are murdering the world right now with those cars.
Electric cars however are just using electricity, doesn't mean that it has to be produced this way or that way, you can have solar panels creating electricity and use that in your car as well it wouldn't really change much, so it would be safe for the world, or you can get it in a bad way as well, it all up to you. Which is why one option murders the world and all humanity currently, while Elon's option give you the freedom to not kill the earth while driving, that is the difference.
