There’s nothing new under the sun – a brief look at historical climate change patents – Part 5: Biofuels
Reducing humanity’s reliance on non-renewable fossil fuels is one of the greatest challenges of our time. Biofuels such as biodiesel and bioethanol represent more sustainable alternatives to their fossil fuel counterparts: petrol and diesel. Lifecycle analysis shows that biodiesel and bioethanol also on the whole have superior environmental performance when compared with fossil fuels in areas such as global warming, fossil depletion and ozone layer depletion1. Is this technology new? Of course not.
