Current biofuels (bioethanol, ethyl tertiary butyl ether (ETBE), hydro-processed vegetable oil and Fatty Acid Methyl Ester (FAME, biodiesel)) are based on traditional agricultural crops which have been grown extensively in the EU and thus there has been no need to carry out dedicated research on their costs and on water consumption as these parameters are well known.
Les biocarburants actuels (bioéthanol, éthyl-tertio-butyl-éther (ETBE), huile végétale hydrotraitée et esther méthylique d'acides gras (EMAG, biodiesel)) sont tirés de cultures agricoles traditionnelles très répandues dans l'UE.
