No,

1. biofuels can not be produced in enough quantity to totally replace
fossil fuels, and

2. they cause just as much global warming and air pollution.

Bio fuels are claimed to be carbon neutral because plants convert the CO2
from their combustion back into carbon and oxygen when they grow. It is
claimed to be a closed cycle so that there is no net increase in CO2 in the
atmosphere.

If biofuels can't replace all fossil fuels, there are several options being
developed that also have the potential to replace fossil fuel.

One estimate is that when we create a practical fusion system, there is
enough fuel on earth to last about twice the time until the Earth is burned
up in the death process of the sun.
