چکیده

The rapidly growing world population and rising consumption of biofuels intensify demands for both food and biofuels. This exaggerates food and fuel shortages. The use of food crops such as corn grain to produce ethanol raises major nutritional and ethical concerns. Nearly 60% of humans in the world are currently malnourished, so the need for grains and other basic foods is critical. Growing crops for fuel squanders land, water and energy resources vital for the production of food for human consumption. Using corn for ethanol increases the price of US beef, chicken, pork, eggs, breads, cereals, and milk more than 10% to 30%. In addition, Jacques Diouf, Director General of the UN Food and Agriculture Organization, reports that using food grains to produce biofuels is already causing food shortages for the poor of the world. Growing crops for biofuel not only ignores the need to reduce fossil energy and land use, but exacerbates the problem of malnourishment worldwide.

Microalgae – Opportunities and Challenges of an Innovative Energy Source

Microalgae produce higher biomass and oil yields than traditional energy crops, and they can be cultivated on marginal land or in seawater. Additional benefits can be achieved from co-production of food, feed and high-value chemicals as well as from environmental services, such as bio-fixation of CO2 and wastewater treatment. However, biotechnical, environmental, and economic challenges need to...

Environmental, economic, and energetic costs and benefits of biodiesel and ethanol biofuels.

Negative environmental consequences of fossil fuels and concerns about petroleum supplies have spurred the search for renewable transportation biofuels. To be a viable alternative, a biofuel should provide a net energy gain, have environmental benefits, be economically competitive, and be producible in large quantities without reducing food supplies. We use these criteria to evaluate, through l...

Sustainability of food, energy and environment with biofuels

Growing reliance on food-based biofuels has created considerable controversy about their impact on food prices and the environment and led to scepticism about their sustainability. This review describes the concept of sustainability in the context of biofuels and then discusses the factors affecting the economic viability of current and next-generation biofuels and their environmental and socia...
