Electric bikes exists. And the grid can be made to be green.
But have you been incentivised to buy an electric bike? Have the manufacturers brought out an electric bike that suits your needs? One that can truly replace the bike you obviously love?
And how green has the grid gotten? Not as green as it could be, although it's slowly getting there in many countries. Putting a halt on projects to make it greener, and in some cases reversing that, though... smh.
There is only so much an individual can do. The main changes are at government and large corporation levels. Us individuals have our hands tied, for the most part.
I have solar panels. I drive a PHEV (mainly as an EV). Part of my pay cheque goes towards planting trees and mangroves in Africa to offset carbon usage. But none of that matters compared to the output of corporations and countries as whole. I can be as green as I like and the benefit to anything is miniscule.
This isn't the fault of us little people. This is the fault of the greedy, and the incompetent, and the deniers "at the top"-- you know, the fuckwits who know they can fix this but don't.
