New and renewable energy systems will play an important role in the sustainable development of a future energy strategy. Recent development in this field has proved that the virtual energy system including new and renewable energy sources is feasible. The promotion of renewable sources of energy is a high priority, for security and diversification of energy supply, environmental protection, and social and economic cohesion.This volume discusses the latest research on new and renewable energy resources and their utilization, emphasizing the present state of the art in the field and potential future development.Contents:Renewable Energy Sources:Promoting Renewable Energies and Energy Efficiency through the M Funding Options (K D Patlitzianas et al.)The Shape of Complete Renewable Energy Systems in the World (H Yamamoto & K Yamaji)Biomass Energy:Municipal Solid Waste Valorisation as Energy for Isolated Communities (G Tavares et al.)Application of Biofuels to Compression Ignition Engines (A Kowalewicz)Solar, Wind, Wave and Geothermal Energy:Directions for Renewable Energy in Canada's Smallest Province (A Trivett)Solar Power Agriculture: A New Paradigm for Energy Production (U Bardi)Greenhouse Gas Emissions:Earth Tube Ventilation System: A Project Pre-Feasibility Analysis Tool (M A A Costa et al.)Greenhouse Gases Emission Reduction in an Urban Bus Fleet: Application to a Case Study in Funchal, Madeira Island (A M Simoes et al.)Gas Production and Utilization:Devolatilisation of Coal-Biomass Blends and Combustion Behavior of Their Chars (P Ciambelli et al.)Hydrogen Fuel Cell Urban Buses Operating in the City of Porto (G A Goncalves et al.)Sustainability Development:Energy in Slovenia and Croatia: Challenges and Possibilities for Sustainability (A Zidansek et al.)Sustainability Assessment as a Basis for the Decision Making in Selection of Energy System (F Begic & N H Afgan)and other papersReadership: Postgraduate students in sustainability science, new and renewable energy and environmental engineering.
