尽管非洲经济发展面临诸多挑战,但增长趋势仍在继续。伴随着各国电力需求的增加,非洲电力基础设施建设充满机遇。非洲水电资源丰富,开发潜力巨大,且80%的可开发水电资源潜能集中在赞比西河、刚果河、尼罗河和尼日尔河四大流域。在“一带一路”倡议下,已有大批中国企业“走出去”投资开发非洲水电项目,推动中非电力基础设施合作。本研究通过大量的数据和资料,总结了四大流域水电资源量与开发程度,对流域内重点已建和规划的水电项目进行了详细介绍。最后,深入分析中国企业目前在非洲水电项目开发中面临的主要问题和挑战,并从战略规划、合作模式、风险防范和人才培养四个方面提出相应建议。 相似文献

The member countries of Southeast Asia have renewable energy sources that never run out like solar energy, wind, geothermal, hydropower, biomass, etc. Geographically, Southeast Asian countries are between two continents that have tropical and humid climate conditions in general, while only Myanmar has a subtropical climate because it is astronomically. This provides easier access to many renewable energy sources. The governments of ASEAN member countries have made several policies and promoted renewable energy to encourage individuals and industries to use renewable energy in the future. This study provides information on the status of renewable energy as a comprehensive substitute for fossils in Southeast Asian countries, which includes the potential for renewable energy in the region and the capacity of renewable energy currently available. The study also provides brief information on the potential of renewable energy, renewable energy targets, and challenges to energy demand in Southeast Asia. In addition, this paper provides several recommendations for renewable energy in Southeast Asian countries. 相似文献

西藏电网建设中的若干工程问题分析 总被引:1,自引:0,他引:1
西藏是我国可再生能源分布种类最全,储量最丰富的省区之一,不但如此,而且至目前为止开发还不到储量的1/10,开发潜力巨大,开发前景广阔。据全国水力资源普查成果及对西藏太阳能、风能和地热能的评估,西藏可再生能源理论储量在2.5亿KW以上,技术可开发量在1.5亿kW以上,若将其部分或全部开发,西藏自身只能消化10%~15%,约90%以上将送往内地参与全国电力平衡,支持内地经济建设即实施西电东送,藏电外送。根据《西藏电力发展"十一五"规划及2020年远景目标》和《西藏水电基地开发及外送总体规划》,初步将西藏水电站分为14个电站群,由14条通道送往内地。风能和太阳能主要分布于那曲,阿里和日喀则等地,未来将在这些地区建若干座大型的光伏和风能电站并与水电并网后将强大的电流送往内地。众所周知,西藏地域辽阔,山高谷深,气象条件复杂,使得每条通道所经之处都是高山峡谷,地形地质条件复杂,水文气象条件恶劣,地质灾害频发和地震多发区,给电网工程建设带来很大的难度,文章对此进行了归类和分析,然后提出了相应的工程处理措施,供今后进行大规模电网建设参考。 相似文献

The South-East Asian countries together have a target to increase the component of renewable energy in their primary energy supply to 23 % by 2025. However, there is a different starting point for the individual country members based on their natural conditions and specific political and regulatory frameworks. The Association of South-East Asia Nations (ASEAN), as the regional-cooperation organization, does not have the authority to intervene in the countries’ national policy for renewable energy. It can only provide inputs to develop renewable energy. However, that can also be challenging because it does not have a portal to access each member’s development of renewable energy utilization. This study aims to observe each ASEAN member’s progress by analyzing historical data. This study also reviews some academic papers to summarize the challenges and obstacles faced by each country. The result suggests that regionally, ASEAN members still rely highly on fossil fuels, especially the total primary supply. Moreover, the share of traditional biomass is also very high. Although, data shows that its use has started to reduce as countries gradually shift to other energy options, unfortunately, mostly to fossil fuel. However, power generation has developed in a positive direction. Historical data shows an increase in renewable energy use for power generation, mainly due to the higher utilization of hydropower. Furthermore, it is strongly recommended for ASEAN to build a monitoring portal of renewable energy to track the progress, so it can provide more precise policy recommendations to its members and establish better energy cooperation between each member in the future. 相似文献

Economic development depends on energy resources and power, which will not change in short future. Itexists and will persist for a long time that energy consumption increases faster than population, and power consumption in-creases faster than energy; The fact that consumption rates of energy resources largely exceeds energy renew rate probablyleads to another global energy crisis. Burning emissions of combustible fuels have badly polluted environment, and threatenedour earth ecological health. It becomes a global task to avoid a terrible ecological disaster. In 21 century, we will face theenvironment and resources pressures in energy resources exploitation and utilization. The sooner we realize this, the better itwill be. We should construct persistent, renewable and clean energy resources system, by devoting great effort to promoteenergy efficiency, optimize energy consumption structure, develop clean coal technology, and advance the exploitation andutilization of new renewable energy resources. So energy resources and electric power can develop in coordination with e-conomy and environment, and more contribution we can do for modernization. 相似文献
