Energy and Sustainability XI

The world’s economy is fuelled by energy. Depletion of resources and severe environmental effects resulting from the continuous use of fossil fuels has motivated an increasing amount of interest in renewable energy resources and the search for sustainable energy policies.  The changes required to progress from an economy mainly focussed on hydrocarbons to one taking advantage of sustainable renewable energy resources require considerable scientific research, as well as the development of new engineering systems. Energy policies and management are of primary importance to achieve the development of sustainability and need to be consistent with recent advances in energy production and distribution. In many cases, the challenges lie as much in the conversion from renewable energies (wind, solar, etc.) to useful forms (electricity, heat, fuel) at an acceptable cost including damage to the environment as in the integration of these resources into the existing infrastructure. The diverse topics covered by the papers in this volume involve collaboration between different disciplines in order to arrive at optimum solutions; they include studies on sustainable energy production, energy efficiency and energy access, renewable energy resources, sustainable buildings, environmental impact and several others.
