Seaweed biofuels: a green alternative that might just save the planet

01 Jul 13

Producing biofuels in the sea removes at a stroke many of the serious problems with conventional biofuels. Many millions of pounds are being invested in seaweed research from Vietnam to Israel to Chile because producing biofuels in the sea removes at a stroke many of the serious problems with conventional biofuels. Though important as greener alternatives to oil, many biofuels are produced from food crops, such as corn and sugar, which drives up global prices in a world where a billion people are already hungry. Biofuel production also consumes increasingly scarce freshwater and the worst examples – those from palm oil – can produce more carbon dioxide than diesel.
