translate English to French: For example, while the role of biofuels as a sustainable alternative to fossil fuel remains uncertain, it is evident that, in a competitive setting, if prices of agricultural feedstocks were to rise faster than energy prices, they would lose their competitiveness in the energy market.
Par exemple, si le rôle des biocarburants en tant que variante durable aux combustibles fossiles demeure incertain, il est manifeste que, dans un contexte concurrentiel, s’ils devaient progresser plus vite que ceux de l’énergie, les prix des matières premières agricoles perdraient leur compétitivité.
