The global stage has a lot to achieve by simply having energy at its beck and call. However, its unavailability could only mean its inefficient use when available. The objective of this study is to determine how various operations with population and gross domestic product (GDP) as resources affect global energy consumption. These operations include overall, technical and scale efficiencies. Data Envelopment Analysis (DEA) technique was used to carry out this study applying it to the world energy consumption from 1995 to 2009. Out of the 15-year period, six years were reported as overall efficient, three years were discovered technical efficient and three years as scale efficient. Indications from this study reiterates for policies to be formulated that are globally favorable and not biased to any continent or country.
