Biofuels make a great deal of sense, when they're made out of waste products.
They don't make a lot of sense when they're the raw material is produced just to turn it into fuel.
Extracting the potential energy out of things like human waste or used deep frying oil is sensible.

From central Midwest and my dad is a farmer...and an important and negative side effect that didn't get mentioned directly is that the increased demand for bio fuels drives increased demand for all inputs. Inputs such as chemicals and farm equipment where those chemicals (namely fertilizer and herbicides/pesticides) are being used more heavily and driving up costs. Farmers take on more agriculture operating (ag-op) loans (I worked in a bank on these loans) and their debt level increases as well increasing dependence on biofuels and continuing the cycle of increasing the use of double cropping and yet even higher inputs costs.

This should be renamed "The Problem with Ethanol". Also, I would love to see a similar study on the energy inputs for producing gasoline.

Rural Kansan here: The rise of ethanol has driven a lot of farmers to install water pipes so they can turn wheat/soy fields into corn fields. That means the demand for corn is high enough you can make more money with one corn crop than you can with the double crop per year the wheat/soy method offers.

After all these years of watching real engineering, this is the first time seeing Brian's face!

You forgot to mention, corn can be feed to livestock and also kind of important in food security while petroleum is not. Huge petroleum refinery also destroys the land, not to mention sometimes it bring disaster to marine life.

10:15 If you look closely, most of the sugarcane area is concentrated in the São Paulo countryside, which is about as far from the Amazon as Ireland is from Italy. The main drivers of deforestation in the Amazon are cattle ranching, soy farming, logging, and mining. The Brazilian southwest itself was mostly devastated by agriculture during the 20th century.

My thermodynamics teacher in College pointed the inefficiency of biofuels 8 years ago

I first recognized there was something wrong with the ethanol industry when they announced they were building a coal fired ethanol plant near my home. Yes, they were going to burn coal to produce biofuel. Not green at all.

‘If humans could eat electricity, they would.’ Need a real engineering out of context video

Wow, who could've guessed? Once again the core issue in the US is lobbying. Legalised bribery, illegal in most other countries. Literally, every core issue you find in the country can easily be tracked down to lobbying.

In Brazil we use 27% of sugarcane ETHANOL in our gasoline

I see mr real engineering has taken a more aggressive stance for the video title since the initial upload; I like it

Its worth biofuel to go in the direction of byproduct priority. A good example is refined waste vegetable oil for diesel engines.
