  well for a start it produces 0 gas emissions at point of use. we still have to sort out tyre fragments and brake dust, and ensure the electricity grid is non-polluting too. but every hybrid car is burning petrol or diesel, just the same as we've been doing for the last 100 years or so. recent research in the uk has shown that plug-in hybrids are often not plugged in because it's too much bother.

    Why not hybrid or plain ICE vehicles powered by biofuels? Even things like waste vegetable oil can be turned into viable fuel, and it can actually be less environmentally destructive than getting rid of it in other ways. ICE technology is very mature, and we currently produce more food than we need and waste much of it. Why not put it all to some use?

    Pretty much any fat could be used in compression ignition engines with the right treatment, any carbohydrates turned into ethanol for spark ignition engines, and all waste wood burned for electric power and domestic heating.

      Biofuels are even less efficient than making hydrogen for a fuel cell. It’s the same as growing cattle for a burger. It’s way less efficient an energy source because you have to grow up to 10 x more feed for the cow than you get out of the burger. You’re better using that land to grow the actual food for you. Same for biofuel. You get relatively little out for the shit tonne of land you need. Still use chemicals which all need energy to make and transport and use. Then you’ve got to cut, transport, process, refine, transport and then use the fuel. Much better to use the land for food or hell, just leave it to be wild and soak up carbon. Then all that energy you were going to use to make the bio fuel, stick it in a battery.

        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.
