Cellulosic Ethanol is produced when wood chips, farm waste, nonfood crops like grass, and other non edible parts of plants are broken down. There are some big environmental pluses for this newer biofuel... croplands wouldn't have to be diverted to create Cellulosic Ethanol and it could reduce greenhouse gas emissions by an amazing 85 percent if it was used in place of conventional fuels. Scientists are getting better everyday at breaking down the tough cellulose molecules in nonfood plants, which in turn creates biofuel. But there are many issues with this process as well... Cellusolic Ethanol is still very expensive and difficult to produce, and it takes a lot more energy to create biofuel from nonfood plants than it does from sugar-cane or corn. And it's not entirely clear how much energy we could produce using this process... one scientist estimated that if we put every single bit of grassland in the US into Cellusolic Ethanol production, it would only be enough to replace 10 percent of the conventional gas we use in our cars every year. Though it has potential as an energy source in the future, until there is a big breakthrough, Cellusolic Ethanol does not seem to be the most efficient biofuel solution... but who knows how the technology will develop down the road?
