Capacity-Power Consumption and Energy-Efficiency Evaluation of Green Wireless Networks

In this paper,we discuss in detail the basic issue of green design and consider an energy efficiency function as the metric to evaluate green cellular networks.Specifically,we investigate the transmit power required for an expected transmission capacity and propose a capacity-power formula based on the energy conservation and the Shannon capacity theorem.Two novel definitions of cell interference depth and handoff dynamic model are introduced and the corresponding expression of energy efficiency function is derived.Numerical results show that the energy efficiency function is closely correlated with the transmitted/received power required and the cell radius.Our work provides a useful basis for research and evaluation on green design and technology of cellular networks.

Green Networking Based Energy Efficient Communications

The mainstream approaches to green networking are discussed first from the view of engineering,including resource consolidation,server virtualization,selective connectedness,and proportional computing.A brief introduction to network virtualization techniques is given then and a virtual node embedding approach is provided.Finally,three kinds of enhanced green networking schemes by network virtualization are proposed,that is enhancement to sever virtualization,resource consolidation and Adaptive Link Rate(ALR).Examples are included to show the virtue of network virtualization to green networking in terms of energy efficient communications.

Development strategy of efficient bio-methane system by focused utilization of distributed biomass

Bio-methane,as a promising renewable green energy,the component and thermal value of which are very close to that of natural gas,indicates an enormous resource potential and could be employed as the alternative of fossil energy through the development of agro-industrial integration and efficient bio-methane system. Establishment of high efficient agro-industrial integrated bio-methane system is an important component of the renewable energy system and also a significant way of emission reduction.

Dual Power Allocation Optimization Based on Stackelberg Game in Heterogeneous Network with Hybrid Energy Supplies

In heterogeneous network with hybrid energy supplies including green energy and on-grid energy, it is imperative to increase the utilization of green energy as well as to improve the utilities of users and networks. As the difference of hybrid energy source in stability and economy, thus, this paper focuses on the network with hybrid energy source, and design the utility of each user in the hybrid energy source system from the perspective of stability, economy and environment pollution. A dual power allocation algorithm based on Stackelberg game to maximize the utilities of users and networks is proposed. In addition, an iteration method is proposed which enables all players to reach the Stackelberg equilibrium(SE). Simulation results validate that players can reach the SE and the utilities of users and networks can be maximization, and the green energy can be efficiently used.

The design of Landscape lighting Based on wind, light, water and other green energy

Taking the ecological, environmental protection as the starting point, in view of our country road lighting with excessive power consumption problems, the paper proposes design scheme of S type spiral lamp that is suitable the coastal city, highway zone by solar energy combined with wind energy generation. This design uses class of S spiral with the highest wind energy utilization rate, and the surface has materials that can absorb solar energy, its structure built in simple and the design fit standard proportion lamp. This design has the advantages of beautiful apnearance, easv to produce, has the very big use value.

Green Marketing and Renewable Energy： Evidence on Motivations and Behaviour in the Aquacultural Market

The purpose of this paper falls within the theoretical framework of green marketing. It investigates the relationships that exist between the motives relating to aquacultural products marketed under the private label of a traditional retailer （Coop）, the attitude towards their purchase, the perception of their quality, their reliability and the willingness to pay for them. Particular importance is given to the green motives, those that lead to a preference for a product made with specific renewable energies such as biogas. The structural equation models （SEM） technique is used to develop propositions representing a theoretical approach to the integration of green marketing, in the context of the process for purchasing Coop brand fish. With regard to distinguishing between the motives, we referred to the approach that sets out three different types of motive： clean, green and ethical. The resulting managerial implications make it possible to assess how much the different types of motive influence the choices of the consumers. Managers will benefit from the results of this paper by understanding better the benefits for consumers of aquacultural products from renewable energy such as biogas. The originality of the paper lies in its focusing on green purchase behaviour in a poorly investigated sector such as that of fish breeding. The paper contributes to an understanding of the factors that influence environmentally responsible purchase behaviour and their exact relationships, that are still unclear in literature. The fact that environmental issues and concerns are constantly changing implies that ongoing research into their influence on consumer behaviour is essential

Environmental Strategies for Design of Sustainable Buildings in Technique of Green Eco-Architecture

Architecture is defined as a symbiosis of function, aesthetics, technology and economics. This paper introduces the concept of development of technology in architecture for a sustainable society. The concept is based on a systemic link building-climate-energy. The scientific analysis of this link allows us to define three technical levels of modern architecture. The lowest level is represented by low energy architecture that gives priority to the element of energy. Climate is defined only by physical parameters here. It is characterized by the production of emissions that deplete the Biocapacity of the Earth. Higher level of architecture is represented by green architecture which gives equal priority to both energy and ecology. Climate is defined by physical and chemical parameters here. It is characterized by the tendency of reduction of emissions production and move towards environmentally clean energy, material and water sources. Sustainable architecture represents the target program of development of human settlements in the interaction of society-energy-ecology. It is characterized by the balance of categories nature-man-technology and by minimizing the emissions production to the extent of their coverage by the Earth＇s ecosystems. This paper introduces design strategy for green building. The basic structure of the strategy defines, and internal structure of the strategy emphasizes, principles and concepts of green buildings. In this strategy, the vital role is played by renewable energy sources as a production technology of the capital provided to man by nature.

To Promote Green Buildings in China: Lessons from the USA and EU

Buildings have contributed to the energy shortage, pollution and global climate change. To promote green buildings is the way access to the sustainable development. Currently, China has issued some regulations and systems to boost the green building. However, problems lie in China and the systems are not effective. USA and EU have rich experiences and fairly sophisticated legislation and policies to develop green building. China may get some lessens from these countries. This paper will make an overview of legal framework and main system of green building in China, then, analyses some important legal systems and typical case related green building in the USA and EU. Further, problems were pointed out in the China based on the comparative analysis of these countries. Lastly, according to the condition in China and lessons from USA and EU, this paper will put some suggests to promote green building, such as, take some measures to enhance the awareness of the stakeholders, create multi- incentive tools and so on.
