Research on Potential Evaluation and Sustainable Development of Rural Biomass Energy in Gansu Province of China

Abstract

The development and utilization of renewable energy is an important way to solve the environmental dilemma. Biomass energy is a kind of renewable energy and one of the most widely distributed and easily accessible energy forms. It has currently become a main direction of renewable energy development. This paper took Gansu Province of China as the research object to calculate its theoretical reserves of biomass energy resources and then evaluate its potential of biomass energy development by using TOPSIS method under different agricultural development and geographical environmental conditions. Spatial autocorrelation analysis was also performed to reveal the spatial distribution and temporal evolution of the potential of biomass energy development in Gansu Province. The results show that: (1) The total reserves of biomass energy resources from agricultural wastes in Gansu Province reach 7.28 × 107 t/year, with equivalent biogas production of about 1.95 × 1010 m3/year. (2) In most counties of Gansu Province, the Ci value is smaller than 0.5000, indicating that the potential of biomass energy development is relatively low in Gansu Province. (3) The spatial agglomeration of biomass energy development potential occurs mainly in the Hexi area, the Gannan area and the Loess Plateau area of East Gansu Province. (4) There is an area with obvious high-low (H-L) agglomeration of biomass energy development potential to the north-west side of the Gannan area with low-low (L-L) agglomeration of biomass energy development potential. It is a key zone to help drive biomass energy development in the Gannan area. (5) The spatial range of positive correlation (high-high and low-low agglomeration) areas shrunk during the evaluation period.

Experimental Study on the Straw Flexible Space Assembly Flood Control System

“…In this regard, the comprehensive use of straw, e.g., in new building materials, and straw building performance has emerged as an important research topic. Many other researchers have studied the comprehensive use of straw as an energy source through combustion for power generation as well as in bio-fermentation [3][4][5][6][7].…”

Herramientas de economía ecológica para la evaluación de la sostenibilidad de biomasas

“…En este estudio se consideraron las biomasas de la industria azucarera, arrocera y los residuos agroforestales, con los datos aportados por la empresa azucarera y el grupo agroforestal pertenecientes al territorio (AZCUBA, 2019) (GAF, 2019). Por otro lado, los estudios actuales se centran en determinar los aportes energéticos (Ozoegwua, 2017), (Jiménez Borges, 2017), (Suzuki, 2017), (Ozturka, 2017), (Ozcan, 2017), (Toklu, 2017), (Li, 2017), (Jiang, 2017), (Burg, 2018), (Zhong, 2018), (Rahayu, 2018), mientras que otros determinan indicadores medioambientales como las reducciones de CO2. De allí se hace necesaria la realización de estudios sobre herramientas o indicadores de economía ecológica (Huella Ecológica, Análisis de Ciclo de Vida [ACV], Análisis Multicriterios para la toma de decisiones [MCDA en inglés]), etc., que permitan evaluar la sostenibilidad de la biomasa con un marco integral de aprovechamiento.…”

Smart Community Energy Cost Optimization Taking User Comfort Level and Renewable Energy Consumption Rate into Consideration

“…By increasing the amount of renewable generation, smart communities can not only reduce the exploitation of fossil energy, but also promote the sustainable development of society [5,6]. In addition, a smart community has the characteristic of local consumption of renewable energy, which is considered to be an effective means of dealing with energy efficiency [7,8]. Therefore, it plays an important role in improving energy 2 of 17 efficiency and promoting the use of low-carbon energy [9,10].…”
