The Nuffield Council on Bioethics has launched a public consultation on the potential of new types of biofuels, such as fuel produced by algae, to provide us with a greener source of renewable energy.
First generation biofuels, such as bioethanol made from corn, have not lived up to expectations. In some cases their net greenhouse gas emissions are not much better than those of fossil fuels and there have been concerns about their impact on the environment, food availability, and farmers and communities in developing countries.
