You're forgetting things like used vegetable oil which is waste that would be thrown away otherwise. Same for the stuff wood pellets are made from, they are typically mostly saw dust and other waste products. This should hopefully cover airplanes and maybe diesel trains and some cars for when electric isn't practical.
Even if you were to start planting crops for biofuels, how much less efficient than solar plus batteries would it be? The problem with solar and especially battery storage is that the materials used to make them are not renewable, and cause all kinds of issues in their mining and manufacturing. We've grown plants sustainably for thousands of years now. I've yet to see anyone make a solar panel from sustainable or recycled materials.
