Several technologies are currently being examined. The JGI is looking to grow genetically modified plants such as poplar trees and switchgrass to produce more ethanol. Another project includes examining microbes that live in a termite's gut and find ways for them to efficiently digest plant material into sugars which are later converted to ethanol. Representatives, though, state that the fruits of such research are years away from public consumption. Other issues like growing biofuels without the use of fossil energy (e.g., gasoline powered tractors, etc.) and toxic fertilizers need to be addressed as well.
