摘要: Global, large-scale use of bioenergy may replace a significant part present fossil fuel use. We show that labor availability and water resources are large compared to those required operate system such size. The study contradicts the assertion by Giampietro et al. [Bioscience 47(9) (1997) 587], provide invincible barriers biofuels. examine requirements under more reasonable assumptions about supply options demand levels. Bioenergy supplies based on dedicated plantations lignocellulosic crops is renewable intensive global energy scenarios (RIGES). find an order magnitude lower than estimates For instance, do not exceed 1 percent estimated total work force in any country. © 2001 Elsevier Science Ltd.
