Access to clean and affordable energy is critical for the realization of the United Nations' Millennium Development Goals, or MDGs. In many developing countries, a large proportion of household energy requirements is met by use of non-commercial fuels such as wood, animal dung, crop residues, etc., and the associated health and environmental hazards of these are well documented. In this work, a scenario analysis of energy requirements in Nigeria's households is carried out to compare estimates between 2005 and 2020 under a reference scenario, with estimates under the assumption that Nigeria will meet the millennium goals. Requirements for energy under the MDG scenario are measured by the impacts on energy use, of a reduction by half, in 2015, (a) the number of household without access to electricity for basic services, (b) the number of households without access to modern energy carriers for cooking, and (c) the number of families living in one-room households in Nigeria's overcrowded urban slums. For these to be achieved, household electricity consumption would increase by about 41% over the study period, while the use of modern fuels would more than double. This migration to the use of modern fuels for cooking results in a reduction in the overall fuelwood consumption, from 5 GJ/capita in 2005, to 2.9 GJ/capita in 2015.
获得清洁且价格合理的能源对于实现联合国千年发展目标(MDGs)至关重要。在许多发展中国家,很大一部分家庭能源需求是通过使用非商业燃料来满足的,如木材、动物粪便、农作物秸秆等,这些燃料对健康和环境造成的危害已有详尽记录。在这项研究中,对尼日利亚家庭的能源需求进行了情景分析,以比较2005年至2020年在参考情景下的估计值,与假设尼日利亚将实现千年目标情况下的估计值。千年发展目标情景下的能源需求是通过衡量以下因素对能源使用的影响来确定的:到2015年,(a)无法获得基本服务用电的家庭数量减半;(b)无法获得用于烹饪的现代能源载体的家庭数量减半;(c)居住在尼日利亚过度拥挤的城市贫民窟中单间家庭的数量减半。为实现这些目标,在研究期间家庭用电量将增加约41%,而现代燃料的使用量将增加一倍多。这种向使用现代燃料烹饪的转变导致总体薪柴消费量从2005年的人均5吉焦降至2015年的人均2.9吉焦。
