In the last four decades, there were several energy crises caused by various factors including peak oil production in majorindustrial nations where energy price increased due to shortage in supply. Back then, energy efficiency improvement was a big subjectto conserve energy. Today, over 80% of current energy needs are derived from fossil fuels, and with the low crude oil price of USD45per barrel there is no conservation incentive for energy users, However, climate change caused by already accelerated emission ofgreenhouse gases into the Earth＇s atmosphere would be aggravated by a combination of low oil prices and abundance of supply.Therefore, corporations should start energy efficiency campaigns for the purpose of combating climate change by reducing greenhousegas emissions especially for process plants with large energy consumption. The campaigns should include energy management, use ofhigh energy efficient equipment and systems that monitor and optimize the use of energy. Energy benchmarking exercises would helpto check and monitor energy efficiency performance level for continuous improvement.
