Improved worldwide energy efficiency in 2015

According to a recent report by the International Energy Agency (IEA)*, world growth was accompanied by a reduction in energy needs during 2015. The amount of energy required for each unit of GNP fell by 1.8% worldwide, following an average annual fall of 0.6% over the past decade. Good news that goes to underline changes and progress in uses in favor of greater energy efficiency.

In the face of growing worldwide energy demand, energy efficiency enables us to improve our consumption. The aim is to make uses less energy-hungry, thereby optimizing energy consumption.

In its latest report published in October 2016, the International Energy Agency (IEA) observes that the 29 member countries of the IEA invested a total of €221 billion in favor of energy efficiency in 2015, which was 6% higher than in 2014. Total energy savings achieved as a result are equivalent to the energy consumption of Japan.

Progress still “too slow”

Despite the reductions observed in energy intensity, national policies need to be consolidated if precise targets are to be set for potential improvements in energy savings, according to IEA experts. The Agency’s Executive Director writes: “Global energy intensity improvements need to reach at least 2.6% per year to put the world on a sustained pathway for a decarbonized energy system. […] Energy efficiency is the one energy resource that all countries possess in abundance.” The IEA therefore recommends a strengthening of public energy policies, particularly with respect to electrical equipment and transport in order to achieve lower energy bills.

Energy efficiency: a strategic issue for ENGIE

Energy efficiency is a key lever in energy transition for cities and businesses. Today, approximately 41% of the total energy demand is accounted for by the residential and tertiary sectors. In view of this, the ENGIE Group has been committed for a number of years to improving the energy performance of buildings: energy balances, renovation plans and supervisory tools have made it possible to introduce increasingly high-performance solutions for the energy management of buildings and facilities.

As the world’s leading supplier of energy efficiency services, ENGIE offers a comprehensive range of hard and soft energy services (energy infrastructures engineering and projects, decentralized energy supply, facilities management, HVAC engineering, etc.) in more than 30 countries.
