Energy environmental and climate policies are inextricably linked. All energy production and consumption has environmental and climate impacts. Whilst it is often tempting to overlook the environment during difficult economic times, the challenges of producing and using energy resources sustainably and protecting our natural environment equally represent an opportunity to pursue sustainable economic growth. Environment deterioration including climate change is one of the greatest challenges of our time and the top environmental priority. In order to cope with the challenges of climate change and promote sustainable development an ambitious and cohesive climate and energy policy is needed at international level. This special issue is to bring together professional opinions on the energy, environmental and climate policy.

Abstract: The second law efficiency is a main tool for evaluating the irreversibility through a system. Models have been applied for multistage flash (MSF) and mechanical vapor compression (MVC) distillation for evaluating the entropy generation at each component in the process. The minimum work of separation (which is the work consider to extract a unit of pure water from a saline feed water) is considered through the study, the entropy generated due to irreversibility plus that of the in-equilibrium of the discharge brine and its mixing with the seawater are important during the calculation of the minimum separation work, its value for MSF is 0.729 kWh/m3. Exergy is a useful concept in the analysis of systems involving both thermal and mechanical energies. The thermal performance of distillers is assessed based on the first and second laws of thermodynamics. This study focused on the analysis of the energy and exergy of MSF and MVC units. The exergy losses due to irreversibility for the subsystems of the units are evaluated, the specific exergy losses of the MSF unit is at the range of 63 kJ/kg. The exergy destruction in heat recovery and heat rejection sections, brine heater and all the other systems are calculated, these values are 61, 17, 10, and 12% respectively. The study showed that, the second law efficiencies of the MSF unit is around 4 % and for the MVC is around 7%, so these law efficiencies clarify that there are many ways to improve the plant performance by reducing the highest exergy destruction through these systems.Abstract: The second law efficiency is a main tool for evaluating the irreversibility through a system.

Abstract: With management, data analysis and spatial information, GIS is now an effective tool in addressing the problem of spatial distribution and environmental change. The research and application of GIS in conjunction with the collection of environment data and water quality into an integrated technology, help managers to make decisions based way, is a need to study the problem research in the framework of environmental protection and sustainable development of the rivers. This topic focuses research and propose integrated solutions and feasible to protect water river in central Vietnam, to ensure the safety of the water supply as well as serving the purpose of sustainable development throughout the river basin, it is necessary to have a good database of spatial distribution of water resources of the basin, the river water quality as well as the potential sources of pollutants.Abstract: With management, data analysis and spatial information, GIS is now an effective tool in addressing the problem of spatial distribution and environmental change.

Abstract: The energy saving and emission reduction in thermal plant is complex, with the open, non-equilibrium and interoperability features. In order to identifying the order parameters affecting plant system, a co-evolution model of energy saving and emission reduction in thermal power plant was built based on synergetic theory. According to the feathers of potential function based on mutation theory, the performance was divided into high efficiency, low efficiency and critical situation three operating states. Then, a dynamic evaluation rule was proposed in order to achieve dynamic performance evaluation on energy saving and emission reduction of thermal power plant. Finally, an empirical analysis of a thermal power plant showed that the order parameter of energy saving and emission reduction in this plant are soot emissionper unit power and grid electricity generation. There existed “high efficiency” and “low efficiency” performance status of energy saving and emission reduction. The performance before June in 2012 was mostly inefficient, things have changed since the investment in energy saving technology projects, the energy saving and emission reduction performance in this plant after June 2012 was highly efficient, which was in line with the actual situation, and proved the validity of this method used in dynamic performance evaluation on energy saving and emission reduction of thermal power plant.Abstract: The energy saving and emission reduction in thermal plant is complex, with the open, non-equilibrium and interoperability features.
