Economic growth is a prerequisite for development while energy is the engine for growth process. In the era of globalization, production cost heavily dependent on energy intensity and efficiency with keeping environmental conditions intact. Therefore, the structuring of a significant environmental index is pre-requisition of the world with energy intensity, energy efficiency. For this objective, this study employs 18-years data set between 2000 and 2018 of Organization for Economic Co-operation and Development (OECD) to form a universal aspect of economics, environmental index, and energy efficiency (EEE). The data envelopment analysis (DEA) and arithmetic mean aggregation in the formation of mathematical aggregation mechanisms are applied for empirical analysis. According to the results, Iceland maintained an overall high rank regarding energy efficiency, energy intensity, and environment followed by Greece, New Zeeland, and Norway. In this investigation, Ireland followed by the UK and the USA are the lowest performer regarding energy and environment. Thus, the study concludes that energy (efficiency & intensity) and environment hold complex relations and needs a special set of policies to address them collectively and it is expected that this study can be used as valuable information for the policymaking process.
经济增长是发展的前提，而能源是增长过程的引擎。在全球化时代，生产成本在很大程度上取决于能源强度和效率，同时要保持环境状况完好无损。因此，构建一个重要的环境指标是世界的前提条件，包括能源强度、能源效率。为此，本研究采用了经济合作与发展组织（OECD）2000 年至 2018 年的 18 年数据集，形成了经济学、环境指数和能源效率（EEE）的普遍方面。数据包络分析（DEA）和算术平均值聚合在数学聚合机制的形成中得到应用。根据研究结果，冰岛在能源效率、能源强度和环境方面一直保持着整体的高排名，其次是希腊、新西兰和挪威。在这项研究中，爱尔兰紧随英国和美国之后，在能源和环境方面表现最差。因此，研究得出结论，能源（效率和强度）和环境之间存在复杂的关系，需要一套特殊的政策来共同解决它们，预计这项研究可以为决策过程提供有价值的信息。
