Almost all biofuels used today cause more greenhouse gas emissions than conventional fuels if the full emissions costs of producing these “green” fuels are taken into account, two studies being published Thursday have concluded.
Destruction of habitat to grow biofuel is a primary reason. Also, using cropland to grown biofuel means less food is grown, something especially of concern in developing countries.
However, some biofuel is not so destructive. This includes biofuel produced from algae, leftovers from agriculture and food processing, and methane from landfills.
If Craig Venter is right, all the above becomes a moot point because new organisms with synthetic genes will be able to create enormous amounts of biofuel from, are you ready, CO2.
