Using biofuels to combat the energy crisis The use of biofuels does not necessarily have a negative impact on food production and thus on food security. The two goals can be combined, as is shown in an SDC project in Cuba. In July 2012 in Guantánamo a plant started work which transforms jatropha seeds into biofuel. Thanks to the Swiss biomass project, six Cuban communes now benefit from cheaper, renewable and reliable energy.
