“For every unit of energy it takes to make domestic biodiesel, 3.5 units are gained”
-Dubious claim. Can you link some science to that statement, or are we just expected to believe you?
-Camelina is not a non-food crop. Cows eat it, and humans eat the vegetable oil. Should we create more farmland to make up the shortfall of vegetable oil? If you want to rotate crops, new land must be cultivated for the crop you kicked out (it sounds like corn is the loser). Again, we need more farmland. If you use marginal land, you will get a marginal yield, yet require the same energy to cultivate and harvest. Again, dubious.
“Biodiesel significantly reduces greenhouse gas emissions.”
-Maybe some gases, but it doesn’t reduce CO2 any more than ethanol. In fact, it’s identical. That’s not much of a benefit when even scientists only hype carbon as the culprit. Unless you are a true believer that global warming is going to harm the planet, of course.
If you are considering algae tanks in deserts to make biodiesel, then it makes good sense to set up a pilot and start running with it. If you are talking about replacing fully utilized farmland, then you are just borrowing from Visa to pay Mastercard.
