交通運輸部門是主要的能源消費之一。在貝里斯,每年的能源消耗逐年成長。在日益增加的全球能源需求和能源成本上漲的情況下,節能成為一個非常重要的問題。能源效率是最好的和能源利用的最常用的指標之一。在交通能源強度是該部門的能源利用效率的措施。本文的主要目的是確定在2000年到2008年,是否在貝里斯的道路運輸子部門有達到能源效率。本文旨在首先利用ASIF框架計算且確定貝里斯交通部門中道路子部門的能源效率的程度。ASIF框架衡量能源效率的關鍵指標的能源強度。能源強度的主要參數是能源消耗、VKM和平均入住。這些參數已被確定,能源強度也已被估計。能源強度和能源效率成反比。能源強度的下降顯示出能源效率的改善,反之亦然。自2000年至2008年,貝里斯的道路客運能源強度下降9.04%。貝里斯交通部門的消費率下降,VKM比率提升,這導致能源強度的衰減。在研究期間,在貝里斯的道路交通部門的能源效率的提高。;The Transport sector is one of the major energy consumers. Energy consumption in Belize is growing every year. In situations of increasing global energy demands and rising energy costs, conserving energy becomes a very important issue. Energy efficiency is one of the best and the most frequently used indicators of energy use. Energy intensity in transport is a measure of the energy efficiency in the sector. The main objective of this paper is to determine whether there was energy efficiency Belize’s Road passenger transport sector from 2000 to 2008. This paper seeks to first of all calculate and determine the level of energy efficiency within the Road passenger transport sector of Belize’s transportation sector through the use of the ASIF framework. ASIF framework measures energy intensity which is a key indicator of energy efficiency. The key parameters of energy intensity are Energy consumption, vkm and average occupancy. These parameters were determined and energy intensity was estimated. Energy intensity and energy efficiency are inversely related. A decline in energy intensity shows an improvement in energy efficiency and vice versa. Energy Intensity in Belize’s road passenger transport decreased 9.04 percent from 2000 to 2008. Consumption rate in Belize’s transportation sector decreased and vkm rate increased; this caused a decrease in energy intensity. During the period of study, there were improvements of energy efficiency in Belize’s road transport sector.
