The raindrop argument is like suggesting that we rebuild a beach a single grain of sand at a time. Le Bourget airport outside of Paris was packed with hundreds of private jets for the Paris conference; all those “important” people nullifying the effects of thousands of Leafs. I stop my raindrop, they start a thunderstorm, so I hardly see the point of spending extra money when the “important” people have no respect for the sacrifices of normal people.
Over 250,000 leaf's have been sold which is still a drop in the bucket but a meaningful one as there are a lot of cars on the road. Further, the poster has solar power and pays "amortized cost is approximately $0.13Kwh" making a gas powered car a far worse option.
