Energy efficiency is significantly impacting global energy demand, reducing consumers’ energy bills, holding back emissions growth and making energy systems more secure.
However, according to the IEA (Dec 2017), ‘global progress has become dependent on yesterday’s policies, with the implementation of new policies slowing. If the world is to transition to a clean energy future, a pipeline of new efficiency policies needs to be coming into force. Instead, the current low rate of implementation risks a backward step.’
True! Here’s a counterfactual that is particularly difficult to grasp in its entirety:
Between 2030 and 2050, climate change is projected to cause about 250,000 additional deaths per year from heat stress, malnutrition and the spread of infectious diseases.

An increasing trend in energy management is the adoption of cloud-based energy management software. Such a cloud-based system can offer increased flexibility, greater capacity and high scalability, while reducing IT expenses.
The challenge is no longer the availability of data. Metering devices and sensor technology have provided us with a deluge of data. It is now a matter of converting these data into key performance indicators  as well as turning it into actionable knowledge.
The reason why the classic ‘technico-economic’ approach is not working optimally is because investments in energy efficiency result in more than a reduction of energy consumption. They also lead to a variety of non-energy benefits.
These include improved product quality, reduced production time, improved health and well-being, reduced environmental footprint etc.
Integrating the multiple energy and non-energy benefits of energy efficiency significantly improves the business case of energy-efficiency investments in the business sector by raising their strategic and financial attractiveness.
Primary energy factors deliver important signals to the markets, act as key drivers for sector coupling, and incentivise certain technologies and fuels while discouraging others.
PEF calculation methods can lead to (un)intended promotion of fossil fuels over renewable sources.
Within the EPBD, a proper PEF calculation is essential to produce a meaningful energy performance certificate.
Due to the increasing share of (especially non-combustible) renewable power, total primary energy gradually loses its function as an efficiency indicator.
