Research On Affect Factors Of Biogas Consumption Preference Of Households Who Have Built Biogas Digesters

With the development of industrialization and urbanization, energy is facing to more and more serious situation. The contradiction of energy supply and demand also becomes more and more intensified. Because of its evident advantages such as cleanness and economy, biogas has become to be a ideal substitutes for the traditional energy. With the development of biogas technology, the use of biogas in rural areas is increasingly widespread. In the rural areas, household biogas digester is the main form of biogas energy. The project of household biogas digesters is highly recommended by government to increase the income of the farmers. Most of the studies about biogas energy in countries we can find mainly focus on the quantity of the biogas digesters while the utilization of the facilities is often ignored. Even if a small amount of researchers pay attention to the research about the use of the digesters, the articles are mainly written from the view of qualitative, so it is lack of micro-empirical survey. Therefore, we explore the significant factors which influent the preference of the biogas consumption households who have built gas pool to find out the suggestions of promoting the project in the countries healthily and sustain ably.Methane in Hubei Province has a long history, and this province has been a good example for the rural biogas development. But the rural built biogas digesters in the province also have the problem of a low utilization rate. The idle or abandoned digester is common situation. Therefore, I made this province as the research object. In this paper, it used typical survey and stratified random sampling methods to collect 409 households who have built biogas pools for more than one year and analyzed the results using SPSS software to answer the questions we asked. Eventually it summarized that the comprehensive incomes of the biogas and biogas slurry,the breeding scale,the number of the farmers working outside in one household, environmental awareness, the number of the local digester biogas technicians and the qualities of the biogas digesters and its parts are the significant factors which affect whether the household using biogas for a long term. In addition, weather and the difficulty of discharging also have important effects on it. From these factors and the realistic problems, this paper will drawn the following policy recommendations:1. Make policies to encourage farmers to use the biogas energy to increase farmers' income and enhance their confidence in a long-term. 2. Make a program before the projects are carried out and rationalize the process of the biogas program. Combine the scale of farming households with the number of migrant workers to make the plan of the rural household biogas project. And improve the process of biogas projects dynamic feedback the adjustment mechanism. In some rural areas in which there is a small number of farming and insufficient breeding, we should promote strong and medium-sized biogas project, and encourage convergent breeding to resolve the problem of the source of methane.3. Upgrade the technological, and expand professional team. We should increase the training of professional technicians and improve the biogas management and maintenance staffs'remuneration packages, so that the farmers can get a strong technical support in using biogas.4. Enhance the level of service and explore a property of scientific management model. First of all, improve the coverage rate of the network and hardware' construction level, so that after-sales service network servicing more people who have built biogas pools. Secondly, tap the local multi-gas service entity to explore the appropriate follow-up service model of the biogas. At last, the staff should change the view, and establish comprehensive information database about the gas user to truly improve the service efficiency.5. Encourage the development of gas equipment companies, and strengthen the supervision and approval of the product quality. First of all, the government should gradually introduce market mechanisms to improve the competitiveness of enterprises; secondly, we should improve the gas quality monitoring system and the examination and approve system; then, strengthen the scientific and technological innovation in the biogas equipment; finally, the service awareness should be enhanced, the business service levels also should be improved.6. Enhance the farmers'environmental awareness; increase the training of the skills of insulation in the winter...
