More and more countries are focusing on the lack of resources with the consumption of large quantities of fossil energy. The Chinese government is actively promoting the policies related to the transformation of the energy structure which will increase the proportion of clean energy consumption and reduce the proportion of fossil energy consumption in order to relieve the pressure on domestic energy. Interest in the generation of biogas from agricultural residues is increasing rapidly due to its climate benefits. This article is committed to analysis the economic performance of the biogas cogeneration energy supply system of livestock and poultry breeding plants in southern China. The model of the biogas cogeneration energy supply system of livestock and poultry breeding plants in southern China and the advices to the government will also been proposed as a result. According to the results, biogas cogeneration system is feasible in economy with reasonable device configuration and operating strategy.

Analysis of Long-Term Plan for Energy Supply System for Latvia that is 100% Based on the Use of Local Energy Resources The prices of fossil energy resources are expected to rise substantially in the future, therefore fossil energy resources might not be a feasible energy source for Latvia in the long term. The establishment of a fully self-sufficient energy supply system will require a significant transformation of the existing energy supply and transport infrastructure. Early planning of such a system makes it possible to shape development of the existing energy system in order to achieve that goal of a fully self-sufficient energy supply system. The paper shows a potential solution to establish an energy and transport system solely based on the domestic primary resources by the year 2050.

Currently, the Chinese government is promoting the transformation of clean energy in rural areas to reduce the consumption of coal to cope with the smog. It is mainly based on “coal to gas”. The development of biomass resources in agricultural areas is an alternative means of energy supply. In order to improve rural energy structure, we propose to upgrade “coal to gas” to “coal to biomass” derived from centralized biogas production (CBP) and straw-briquetting fuel (SBF). This study deals with the question of financing such projects. The public–private partnership (PPP) model is seen as a response that can mobilize social capital to finance investments in these new modes of production and energy supply in rural areas. Based on an analysis of the strengths, weaknesses, opportunities and threats (SWOT) of the two projects considered above, an analytic hierarchy process (AHP) was carried out with the assistance of experts in order to clarify the strategic choices which are more suitable for investors. First, we built a PPP strategic-decision model. The decision model was divided into four strategies (pioneering strategy, struggling strategy, conservative strategy and striving strategy) and two development intensities (conservative and proactive). We used this method to construct a SWOT–AHP model of the PPP strategy for CBP and SBF based on the investigation from the experts. The strategic-decision model identified that a pioneering strategy based on opportunity type is promised for SBF, while a more aggressive type strategy in struggling strategy is essential for the CBP. In order to encourage investors to adopt a positive and optimistic attitude towards the two projects, the public authorities have a role of guidance to ensure the mobilization of the social capital necessary for the construction of the projects.

In 2009, Chinese government proposed the 15% target of non-fossil energy share at 2020, and obtained the general concern of the international community. The paper considers the constraints of economic growth, decrease rate of GDP CO2 intensity and primary energy structure to discuss China’s CO2 emissions and primary energy demand in sub-scenarios. Then through the analysis of consistency with the overall economic growth and energy planning and the international society’s expectation on China’s GHG abatement duty to demonstrate the feasibility of the non-fossil energy target. The results show that the 17% of non-fossil energy can meet the various constraints. Finally pathways to realize clean energy development into 2020 are outlined.

Topological Models

In the design and operation of energy intensive systems, the possibility of improving the system’s efficiency is very important to explore. The main way of improving efficiency is through optimisation. This paper describes the application of exergy topological models and, in particular, the graph of thermoeconomical expenditure for thermoeconomical optimal design s of circled nets for energy supply (CNES). The questions of thermoeconomical optimisation of CNES, as well as suggested modelling algorithms, are illustrated in the numerical example of the optimisation of a energy supply system for a city with seven regions of energy consumption.
