Global trends and development of energy services industry in China

Energy service is an effective way to promote energy conservation by market mechanisms,including energy saving services,energy procurement,supply of many varieties of energy,supply of renewable energy technologies,energy-related consulting services,risk management,etc.China is a major energy consumer but energy is in short supply,and the efficiency of energy use is low.China's energy service industry has expanded rapidly,in terms of both the number of new Energy Service Companies entering the market and amount of capital invested in Energy Performance Contracting projects,but the energy service sector in China is still at an early stage of development.Developed countries began early in developing the energy service sector and their energy service market is mature,and the experience of developed countries shows that energy services play a significant role in advancing energy saving and emission reduction.Under the new situation,China needs combine energy services experience of developed countries,and take following measures to accelerate China's energy services rapid and healthy development,including the long-term aspects of policy planning,energy-saving core technology,finance and capital investment,public sector reductions,personnel training,and so on.

Energy Saving,Environmental Protection:Top Priority in China's Development——Exclusive interview with Dr.Yonglong L,Secretary-general,Chinese Committee for SCOPE(Scientific Committee on Problems of the Environment/ICSU).

Energy saving,emission reduction and economic development are major issues China has to meet in building a harmonious society.On one hand,China should pursue a sustainable,fast and sound economic development,on the other hand,she should try to decrease the overuse of energy resources and the environ- mental problems caused by the rapid economic growth. In this regard,on June 24,the Standing Committee of National People's Congress deliberated the draft of Energy Saving Law,according to which China is to take"resources saving"as a basic national policy.This is a key issue to the long-term benefits of China.With relevant questions,China's Foreign Trade interviewed Dr, Yonglong L(?),Secretary-general,Chinese Committee for SCOPE(Scientific Committee on Problems of the Environment/ICSU).and Research Professor at the Chinese Academy of Sciences. Let's listen to Dr.L(?)'s comments with wisdom.

Development of a Composite Eco-Material Based on Typha from a Clay Matrix

This work focuses on the design of a new type of eco-material based on Typha“Domingensis”and clay from the south of the Republic of Benin through various dosages.Three particle size classes of typha shavings were selected to be mixed with two types of clayin order to make parallelepiped shaped samples ready for experimentation.The massive use of these briquettes thus obtained,in the construction of habitats,would not only contribute to reducing the energy consumption inside the dwellings but also would limit the invasion of the waterways of Benin,which would facilitate navigation,fishing and river sanitation activities.In addition,this biosourced,low-polluting material would contribute to improving the energy transition by integrating it into rehabilitation of buildings.
