Factors Influencing Adoption of Biomass Energy Conservation Technologies in Selected Areas of Kitui County, Kenya

In Kenya, demand for biomass energy has increased due to increasing population and urbanization and high cost of alternative energy sources. This coupled with use of inefficient production and utilization technologies, has led to increased deforestation, environmental degradation and increased health impacts. In Kenya, a number of improved technologies have been developed and promoted;however, adoption still remains low. This study sought to assess factors influencing adoption of biomass energy conservation technologies in four selected areas of Kitui County, Kenya. Data were collected using a structured questionnaire and guidelines for institutional and focus group discussions. Sampling was done through purposive and stratified random sampling. Results revealed three categories of biomass energy conservation technologies: energy saving stoves (46%), woodlots (9%) and improved charcoal conversion kilns (2%). The mean percentage adoption rate in the four study areas stood at 48% with Chuluni having the highest (51%) while Kitui West had the least (46%). Agriculture (28%), forestry (26%) and NGOs (Non-Governmental Organizations)/CBOs (Community-Based Organizations)(23%) were indicated as the main sources of information, while field days (35%), community trainings (30%) and demonstrations sites (22%) were the most preferred dissemination channels. High cost of technologies, lack of awareness, financial constraints, cultural preferences, gender aspects, lack of follow up programmes and inadequate capacity to enforce implementation of existing energy policies and regulation were indicated as key constraints to adoption of technologies. The study recommends development of a joint implementation strategy and follow up programmes that will look at the cost of technologies, dissemination channels and involvement of stakeholders’ in development and dissemination of biomass energy conservation technologies.

Analysis of Technical Energy Conservation Potential of China’s Energy Consumption Sectors

It is necessary for China to refocus its energy conservation effort from the industrial sector (field) to all three sectors simultaneously, i.e. industry, construction and transport. In addition, it should also make significant effort for conserving energy on general technical equipment that are used in large quantities and for a variety of applications. Therefore, there is a need to integrate industrial, construction and transport sectors, i.e. the integration between key technologies and widely used technologies, between hard and soft management, between energy-saving technologies and comprehensive resource utilization technologies. According to estimates, if China’s energy consuming sectors adopted appropriate energy-saving technologies, total energy-savings (using 2010 as the baseline) would be 200 million, 450 million, 650 million and 800 million tons of standard coal in 2015, 2020, 2025 and 2030, respectively.
