Biodiesel can reduce greenhouse gases by 78% compared with petroleum diesel fuel. It is produced from domestic feedstocks. It has powered the tour buses for Neil Young and Willie Nelson. It's more biodegradable than sugar and less toxic than table salt, and the production process can take place on a massive industrial scale or gallon by gallon in your garage. In this essential new book, Pahl shares the history of biodiesel, explains the technology in straightforward terms, and explores its exciting potential in the United States and beyond, including resources you can use to buy or make your own biodiesel.
