Sustainable Energy Management in Data Centers through Collaboration

Airlines are extremely energy intensive. Around the world airlines are increasingly focusing on the environmentally sustainable energy management. Using a qualitative longitudinal case study research approach, this study examines Finnair’s sustainable energy management over the period 2010 to 2019. The airline’s major energy source is jet fuel used for the operation of the airline’s aircraft fleet and the electricity which is used to power its facilities located at Helsinki Airport. The study found that Finnair’s annual jet fuel consumption has grown throughout the study due to the airline’s route network and aircraft fleet expansion. The fuel required for ground vehicles has risen reflecting greater operational requirements due to the company’s expansion. The annual consumption of electricity and electricity for heating has displayed a general downward trend during the study period. The annual electricity per passenger has also decreased despite the large growth in passenger numbers. Finnair has increased its use of renewable energy sources for its flight and ground operations. A key energy saving strategy has been the acquisition and operation of a modern state-of-the-art, fuel efficient aircraft fleet.

The aim of the study is to analyze the underlying reasons for the countries to have access to the energy reserves and the effort to be to holding on those reserves. Energy is the driving force for the production of goods and services. Countries who have access to energy reserves are aware that those reserves provide both economic and political power. The motive for countries to have control of energy reserves are twofold: basis for economic growth and keeping or gaining political power. The result most of the time is a continous power struggle between the countries.

Time Required

An efficient scheduling reduces the time required to process the jobs, and energy management decreases the service cost as well as increases the lifetime of a battery. A balanced trade-off between the energy consumed and processing time gives an ideal objective for scheduling jobs in data centers and battery based devices. An online multiprocessor scheduling multiprocessor with bounded speed (MBS) is proposed in this paper. The objective of MBS is to minimize the importance-based flow time plus energy (IbFt+E), wherein the jobs arrive over time and the job’s sizes are known only at completion time. Every processor can execute at a different speed, to reduce the energy consumption. MBS is using the tradition power function and bounded speed model. The functioning of MBS is evaluated by utilizing potential function analysis against an offline adversary. For processors m ≥ 2, MBS is O(1)-competitive. The working of a set of jobs is simulated to compare MBS with the best known non-clairvoyant scheduling. The comparative analysis shows that the MBS outperforms other algorithms. The competitiveness of MBS is the least to date.
