Of fossil fuels.
I can tell you something. I have two hybrid cars, one for me and one for my wife. It cost me, I think, $80,000 more to get those two hybrid cars, and I had no support for that. Why? If you go anywhere in Europe, you get support for that.
The only place you're welcome if you have a hybrid car is at IKEA, because there is private parking for every hybrid or electric car.
