Trends in Energy Efficiency
Efficient energy use, sometimes simply called energy efficiency, is the goal to reduce the amount of energy required to provide products and services. Energy efficiency has to be increased at all stages of the energy chain, from generation to final consumption. At the same time, the benefits of energy efficiency must outweigh the costs, for instance those that result from carrying out renovations.
Global energy efficiency has seen positive signs across developed and developing countries. This has resulted in energy savings of 450 million of oil equivalent in 2015. If this can be put in a simpler perspective, the quantity of energy saved could power the whole of Japan for a year. These savings also resulted in reduction of total energy expenditure by $540 billion, another startling fact.
