摘要：With the current phenomena of increasing food and oil prices there is an urgent need to scrutinize the controversial role of biofuels. They have recently been considered as both the promising source of inexpensive and sustainable energy and the underlying reason for soaring agricultural commodity prices. Owing to gradually growing population, that is forecast to reach 9 billion by 2050, and developing countries having higher standard of living, the society is faced with a great challenge of increased demand for food and energy never seen before. This, combined with declining oil reserves and substantial greenhouse gas emissions, has made groups of scientist, policy-makers as well as companies turn to the use of biofuels. The purpose of this paper is to conduct an analysis on the economic and environmental impact of large scale biofuels production with respect to food price spikes, energy-efficiency and carbon-debt issues.
