Containing papers presented at the 7th International Conference on Energy and Sustainability, this volume includes collaborative research between different disciplines, including materials, energy networks, new energy resources, storage solutions, waste to energy systems, smart grids and many other related subjects.Energy production and distribution matters as well as the need to respond to the modern world¿s dependency on conventional fuels are topics of growing importance. The use of fossil fuels has generated an increasing amount of interest in renewable energy resources and the search for maintainable energy policies.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. Challenges lie as much in the conversion from renewable energies such as wind and solar to useful forms like electricity, heat and fuel at an acceptable cost (including environmental damage) as in the integration of these resources into an existing infrastructure.A range of topics are covered, including: Energy Management; Energy Efficiency; Green Buildings; Energy and Transport; Biomass and Biofuels; Environment and Energy: Connection and Opportunities; Renewable Energy Sources; Waste to Energy; CO2 Capturing and Management; Case Studies; Processing of Oil and Gas.
