Title: Sustainability Concept for Energy and Environment Systems

Abstract: Sustainability has become an unavoidable issue in all major planning and undertaking that involve future use of energy, water and any other natural resources. In order to ensure   sustainable growth of our society, we must satisfy the sustainability criteria and meet the constraints imposed by the limits of all natural resources and the dynamics of their natural renewal. But how do we quantify and measure sustainability and how do we ensure that the sustainability requirements are fulfilled? We consider sustainability concept for energy, and environmental systems and its interaction with current major global trends: globalization, democratization and decentralization. In the assessment of global energy resources we consider the current resource consumption and possible scenarios for meeting future demands. We then move to the definition of sustainability concept. In order to introduce the measure of sustainability, we focus on possible definition of respective criteria with specific application to the energy system design. It is argued that multi-criteria sustainability measurements of options for an energy system must be based on four sets of indicators: technological efficiency, economic, environmental and social indicators.

Keywords: sustainability, energy, water and environment system, resources, limits

Title: Biofuel Impacts on World Food Supply: Use of Fossil Fuel, Land and Water Resources

Abstract: The rapidly growing world population and rising consumption of biofuels are increasing demand for both food and biofuels. This exaggerates both food and fuel shortages. Using 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 U.S. beef, chicken, pork, eggs, breads, cereals, and milk more than 10% to 30%. In addition, Jacques Diouf, Director General of the U.N. 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.
