不久前在布宣诺斯埃力斯举行的第18届世界能源代表大会(WEC)上,阿根廷总统费尔南多·德拉瓦在他的开幕词里指出:现代能源服务为全人类造福是全世界和平、和谐、可持续发展的关键。本次大会是在美国遭遇“9.11”恐怖袭击事件后的背景下召开的。来自全球99个国家的工业界和政府部门的专家一致认为要有效预防针对能源基础设施的任何恐怖威胁,就必须保持长期警惕并建立应对突发事件的紧急预案,但协调合作 相似文献

提高能源使用效率,缓解国内日趋紧张的能源危机,减少环境污染程度,是当前工作重点之一。本文根据我国能源现状,借鉴国外成功缓解能源资源短缺的发展经验,从宏观视角提出将综合能源利用率高、污染物排放少和安全可靠的分布式能源系统进行及时地研发及推广,并将其作为缓解我国能源紧张状况及相应改善环境问题的有效途径,同时提出政府在能源政策方面的导向和支持将有助于分布式能源系统在我国的实际应用。 相似文献

The electricity sector in East Africa is characterized by high levels of electricity losses. The literature has extensively focused on investments and policy reforms that can potentially reduce losses. In this paper, we follow another approach by nonparametrically estimating the minimal losses given the actual inputs, outputs and electricity generation process. Minimal losses are then compared to actual losses to construct quality performance indicators. Using a tailored database for six East African countries over 10 years, we show that electricity losses could be reduced by 8%, representing savings of approximately $60 million per year. 相似文献

This study examines the relationship between financial inclusion and energy poverty reduction, proxied with access to electricity and clean cooking technologies and fuels, using data from 23 Sub-Saharan African (SSA) countries from 2004 to 2019. Evidence from dynamic ordinary least squares, fully modified ordinary least squares, and canonical correlation regression techniques showed that financial inclusion significantly reduces energy poverty in SSA. However, financial inclusion's impact on energy poverty reduction differs significantly among individual SSA countries. We recommend that policies promoting financial inclusion would reduce energy poverty. 相似文献

The six-region climatic map used in the current South African National Standards SANS 10400XA and SANS 204 does not support quantified design decisions within the built environment or indicate the amount of cooling and heating energy required per climatic region. An alternative set of maps based on interpreted degree-days is presented and can be used for regulation and design strategies. A dataset of 21 years of hourly, 0.05-degree data was used to produce a map with discrete heating and cooling degree-day classes. The resultant zones are therefore not derived from only the dominant climatic characteristics, but from simultaneous annual heating and cooling demands. The advantage is that the new map enables adaptive building design for climates with significant diurnal or annual temperature swings, making it useful for regulators and designers. A good correlation exists between the developed degree-day indices and building energy. The majority of South Africa was found to fall within the medium heating/medium cooling zone as expected; however, the KwaZulu-Natal coastal region is within the medium cooling zone and not the expected high cooling zone. This may be due to the humidity levels that are not accounted for. 相似文献

The paper presents the status of electricity transmission grids in the Energy Community of South East Europe (ECSEE): Albania, Bosnia–Herzegovina, Bulgaria, Croatia, Macedonia, Montenegro, Romania, Serbia, UNM in Kosovo. It overviews political and legal aspects of transmission, explaining the impact of the Energy Community Treaty and of the acquis communautaire on energy on the transmission sector. It summarizes the status and the capacity of the interconnections among countries and the current level of cross-border electricity trades. It discusses the need and criteria for electricity transmission investments in the ECSEE. 相似文献

东部非洲厄立特里亚矿产资源丰富,Augaro金矿区位于该国最大的碧莎(Bisha)—扎拉(Zara)铜金成矿带内。通过地质调查发现金矿主要富集于石英脉中,第二期呈灰白、粉红色石英脉为主要的赋矿脉体;通过地球化学水系沉积物勘查,圈出9处Au元素异常区域,结合其他元素异常分布、套合关系及成矿地质背景,判断不同元素异常的内在联系,共圈定10处综合异常区域;通过地球物理磁异常勘查,测区的北部异常区呈椭圆状,中部呈现较为复杂正磁异常,南部主要为负磁异常。结合石英-硫化物型金矿高阻高极化激电异常特征,对激电异常进行综合分析,圈出具有较好成矿背景的异常带。综合分析Augaro金矿特征,判断该矿区具有良好的找矿前景。 相似文献
