...At best that example is a case of .. .1st .. 1 step backward (making things worse) .. then (only after they are forced to) 1 step forward .. if it hadn't been for the need to force them to fix it .. it might have just been -1+1=0 no net change overall .. but .. they did have to force them .. and they arguably did the bare minimum fix .. ie . overall it is more of an example of the opposite.


...The very best most efficient photo synthesis known is only about ~8% .. compared to the very best Photovoltaic over 40% .. and co-generation photovoltaic and solar thermal combined systems have been able to get around ~80% .. then it only gets worse .. the RE-Bio has less efficient steps to then apply that harvested solar energy to get desired work out of it .. like move a car .. heat a house .. etc.


At the current state .. it would actually take at least several dozens of major improvements .. or hundreds of small ones .. and even if that were to happen tomorrow .. that's just in the lab .. they are still decades behind in deployment of those .. and that is just to get them up to where other RE like Solar/Wind are already at today .. and while Bio-Re is trying to play catch-up it isn't like the Solar/wind is just waiting for them .. they keep moving too.

If you compare a new vehicle today to a vehicle made in the 70s, you will see a huge difference in efficiency and emissions. Who's to say the trend won't continue? One big factor for EV supporters is the cheap price of electricity. Electricity will not be so cheap if you take out the fossil fuel factor, and when you add in a huge additional load from electric powered vehicles.


Biofuel:


After doing some research (including reading a scholarly paper), my sources have not really presented any major reason why we are not using cellulosic biofuel. Would someone like to share? The major reason the paper presented is that it would compete with people who want firewood, etc. But there is a lot of waste in this country.
