This article systematizes the experience of conducting energy audits of production facilities and municipal establishments in the form of recommendations. The purpose of the analysis is to substantiate the criteria for an effective energy audit for thermal power stations. The object of the study is the formal and regulatory content of such criteria. The subject of the analysis (a prerequisite for...
With growing attention to energy conservation and emission reduction, solar energy is used in various fields as the basic renewable energy source and the maximum amount of energy that can be exploited in the world today is used in various fields. Therefore, a composite type combined heating operation mode based on solar collector, ground source heat pump and heat storage electric boiler in the integration...
Nowadays the world faces the global warming crisis, and countries all over the world are trying to develop low-carbon economy. It is a huge challenge for China to change from the traditional economy mode into a low-carbon economy mode. This paper puts forward that it is urgent to develop low-carbon economy for China by comparing the "total energy consumption" with the "ten thousand...
The economic development of Shanghai now is strictly restrained by exhausting of fossil fuel, deterioration of ecological environment and lacking of raw materials and natural resources. How to break through the bottleneck and find a sustainable way of growth becomes a matter of prime importance to Shanghai. The 3-IN (Internet, Information, Innovation) entrepreneurial model proposed in this paper is...
Coordinated development of resources, environment, economy and society in Henan province during the years of 1990-2007 as an example is made by empirical research. Conclusions such as physical capital investment and energy are important input factors, the utilization of number of employed persons is low, and inputs of resources and the environment made inadequate contribution to the social system...
In the background of the rapid urban development, the conflict between population, economy, and environment are intensified and appear complexity. Based on the features of city, the index system was set up to reflect the development of city. The coordinate assessment system of population, economy, and environment is established in the scale of city size by principal component analysis, etc. The demonstration...
The current condition of rural energy consumption in Zhejiang Province was investigated. According to the actual situation of new countryside construction, countermeasures were put forward on how to develop rural energy including enhancing the rural energy planning, popularizing suitable technology mode, increasing input, and accelerating technology supporting capacity through an analysis on the potency...
This study aimed to explore main factors influencing energy consumption patterns, and investigate which one had main effect in the cities of developing China having greater than two million populations. 40 parameters related to city energy consumption of core areas of 21 major cities with population above two million were collected from statistical data for 2006. These parameters were divided into...
Urban traffic has become a worldwide problem with the economy developing rapidly, which synthesizes out-of-order jam, energy consumption and GHG emission. An autonomic model is proposed based on the micro behavior simulation of urban traffic, in which an information decision factor is introduced. Thus the travel patterns and choice of the road trip have been controlled and optimized dynamically. Simulation...
The value in identifying current trends and viewing them in a historical light is that the results can be used to inform ongoing policy and investment decisions. This paper highlights historic and current patterns in human population, energy use, and culture, with technological development as both a facilitating and resultant factor. It is shown that there is a positive relationship between national...
Energy efficiency improvement is the requirements of guaranteeing state security and sustainable development of economy. In this paper, we study the relationship among fixed asset investments on information technology, R&D and energy efficiency to find the way of improving energy efficiency. We construct a model based on data from U.S.A, in which the cooperative work of fixed asset investments...
Praca zawiera przegląd agregatów uprawowo-siewnych i nawozowo-siewnych z analizą ich głównych cech konstrukcyjnych i funkcjonalnych. Wskazano na korzystne efekty agrotechniczne i ekonomiczne, jakie można uzyskać podczas pracy tymi agregatami w tradycyjnym systemie uprawy roli.
W pracy przedstawiono przegląd agregatów do uprawy bezpłużnej i do siewu bezpośredniego z analizą ich głównych cech konstrukcyjnych i funkcjonalnych. Ponadto zamieszczono analizę ekonomiczną eksploatacji agregatów w trzech systemach uprawy roli. W podsumowaniu wykazano związek agregatów rolniczych z postępem w technologii uprawy roli.
