Recent engineering advances in energy production, environment protection, and network technologies have contributed to the successful solution of real problems thus improving the quality of life and making the power transformation sustainable for the environment. The deep impact of the rising influence of the economy in nearly all human activity, as well as the many risks of energy production on the environment and health, ask for the innovative solution of complex nonlinear engineering problems. Pressing demand on energy together with the sustainability of the environment has opened new perspectives in the renewable sources, and in the development of renewable energies.

The solicited papers in this special issue should provide solutions on mathematical problems in sustainable energy, with modeling, analysis and control problems, communication systems, process control, environmental systems, intelligent manufacturing systems, transportation systems, and structural systems. A peculiar attention to a rigorous mathematical physics definition of the problems is the special feature requested to the papers. Potential topics include, but are not limited to:

• Optimization of energy systems and devices: design, integration, transportation, implementation, and smart grid
• Mathematical approaches to renewable and alternative energy technologies
• Sensing and monitoring technologies for sustainable energy and environment
• Intelligent data analysis
• Solar: heating and cooling, concentrating solar power, buildings, and conservation
• Biofuels and organic photovoltaics
• Mathematical treatment of fuel cell, wind, tidal, wave, hydrogen, and geothermal energy
• Biodiversity preservation modeling, and energy/economics sustainable modeling
• Practical engineering: nanotechnologies, environmental chemistry, water management, emergency management, industrial ecology, waste technologies, antidrought systems, energy, and forcing action in climate change
