Abstract: The Middle East is an energy rich region and an important strategic position. At present the Middle East has been undergoing a radical political and social transformation since the Middle East Upheaval, Great powers focus on this region. The Middle East economies are highly complementary to Chinese economy. As the rapid growth of energy demand power, Chinese energy investment in Middle East is growing. It is necessary for China to increase trade and investment in the Middle East, to promote economic integration and common prosperity. This paper will analyze the opportunities of Chinese energy investment in the Middle East from the view of the growth of Chinese global trade and investment, RMB internationalization strategy, the traditional friendship between China and the Middle East and so on. Meanwhile this paper will also study severe challenges of Chinese energy investment in the Middle East, such as religious conflict, the Iran nuclear issue, cultural difference, and try to provide countermeasures on basis of the analysis of multiple influence factors of construction the economic corridor in the world, in order to eliminate the barriers to energy investment, to strengthen the currency in circulation and to realize mutual benefit and win-win cooperation.

Abstract: In the sustained rapid growth of the international economy, foreign investment and international business is becoming the next mainstream context, China vigorously implement the "going out" strategy, encouraging foreign investment. With economic growth, the rapid growth of the world's water and electricity consumption are also in the growing strength of China's hydropower companies powerful premise, accelerate the development of hydropower projects overseas investment is an inevitable trend. This is not only of significance for the development of major hydropower companies, while the international operations of Chinese enterprises to China’s energy security, energy policy have far-reaching implications. But the ever-changing international situation and uncertainty investment host country's investment environment for foreign investment in hydropower projects risk assessment and prevention challenges. Hydropower projects overseas investment risks should not be underestimated, risk assessment and prevention of improper investment will bring huge losses. This paper studies the characteristics of China's hydropower projects overseas investment risks and prevention.

Abstract: For the problem of interval multiple attribute group decision-making, this paper studies the Cloud-PROMETHEE method. First, we can obtain the comprehensive weight. Second, we transform the interval decision matrix into cloud by cloud model because of randomness and fuzziness of date information. With the help of the PROMETHEE, we use overall priority index to determine the order of alternatives. Finally, an example concerns analysis, which is the risk analysis of planning process of new energy products, is given to show the feasibility and availability of the method.

Abstract: In this paper, we firstly review the paper related to index system of economic society development, and divide and analyze the stage of Chinese economic development by using the theory of Chenery, Hoffman and Lewis. Then we selected indicators by using GRA and FA, and also consider the cointegration relationship of these indicators with power. Finally, we propose the index system of economic society development based on the medium and long-term electric power demand forecasting, which included 3 first-level indexes, 7 second-level indicators.

Abstract: The author uses a SWOT method to analyze the advantage, weaknesses, opportunities and threats of Hexi new energy industry base.And on this basis,the author put forward a suggestion and countermeasures of new energy industry base, such as SO Strategies, ST Strategies, WO Strategies, and WT Strategies. Then,the article comes up with some suggestions to promote the development of the new energy base .

Abstract: This paper builds an input-output framework based on a data envelopment analysis (DEA) window aimed at exploring total-factor energy efficiency (TFEE) in 30 administrative regions and 6 areas across China from 2006 to 2012. In this framework, labor force, capital stock, energy consumption, CO2 emission are regarded as inputs, while gross domestic product (GDP) as the single output. The result indicates regions in East China and Mid South perform relatively higher TFEE especially Jiangsu, Guangdong which both obtain optimal efficiencies, while regions in Northwest have lower TFEE like Ningxia and Qinghai which TFEE lower than 0.55. But on the whole, 6 areas of China show increasing trends of TFEE during this period. Additionally, we conduct a regression analysis aimed at revealing influence factors of energy efficiency. We find properly adjusting industrial construction contributes the best for lifting TFEE, meanwhile, technology and economy size also have marked influences in raising TFEE.

Abstract: With increasing trend of nuclear family, modern society is also showing a gradual increase in single households. Increase in single household leads to increased use of home appliances. Accordingly, the aim of this study was to examine ownership of electric home appliances (home appliance products that use electricity) and energy consumption status and to obtain implications for energy conservation.A survey was conducted / analyzed on 2,250 households, and the following results were obtained. First, ratio of home appliance ownership and number of appliances per household member were examined. Average number of home appliances was 10.6 for single households, 13.8 for 2-person households and 17.5 for households with 6 persons or more. Second, electric rate was found to be 46,000 won for single households and 114,000 won for households with 6 persons or more. Electric rate per member of household was rapidly reduced from <single household> to <4-person household>, showing about 50% conservation. In other words, increase in single households is regarded to have great impact on increase in energy consumption.

Abstract: Electricity price reform aims at improving resource allocation and energy saving. In this paper, The latest input-output data and price affect partial-closed model are used to measure the impacts of electricity price reform for the whole society, energy industry and the residents con- sumptions. The results indicate that electricity price reform had limited impacts on GDP and resi- dents’ consumption, and the impacts on mining industryand energy industry are more significant than others. The policy certainly achieved the aim to adjust energy structure and promoted the co -ordinated development of urban and rural economy.

Abstract: According to the international coal trade data of the years from 1996 to 2011 published by UN COMTRADE (UNSD), it can be inferred that the data is mainly about international trade of raw coal and related coal products. By adopting the theory of complex network analysis, this paper calculates the complex network of international coal trade in the aspect of its density, node degree, centrality, point strength, clustering coefficient. Based on these properties, this paper further analyzes the evolution rule for international coal trade network of raw coal, coal briquettes and ovate coal over the last 16 years, as well as the difference between the pre-and after financial crisis.

Abstract: Sunlight generation in the schoolyard and geothermal generation are typical examples. However, from someday, sunlight generation is not doing its function enough. Many schools are trying to utilize renewable energy. But, in most of the cases, unlike preliminary plans, schools are not substantially utilizing renewable energy efficiently. In order to maximize the energy efficiency of school’s renewable energy, multiple renewable energy needs to be comprehensively combined and applied. The current method of solar energy is used in the rooftops of schools. Geothermal energy is installed using the large area of the schoolyard. Acupressure energy device using piezoelectric element is installed in the school gate, the 1^st floor stairway, and the school building’s main entrance. Also, in the school’s streetlamps, noiseless, small wind energy generator is installed to generate wind energy. In conclusion, efficiently applying solar energy, geothermal energy, acupressure energy, wind energy will increase the school’s renewable energy effect.
