Its not an excuse. Oil is the cheapest and most cost-efficient energy generator in our entire human species. A gas engine is the simplest, most energy-generating device ever created. When you advocate for alcohol, you want to downgrade this. No one is against alcohol, but rather forced replacement the same way tyrants want to abolish gas-powered cars under the excuse of "saving the environment", when an electric car emits more polluants than four gas cars as it leaves the factory because of its extremely expensive and dirty batteries.

But go ahead and tell me how alcohol is great and how every farmer needs to stop growing your food to fuel a car that could be fuelled by fracking.
