Until now, the building energy standards that have prevailed in Europe have been technical specifications recommending the implementation of technologies and solutions to achieve a partial technical performance. For example, this is the case in Switzerland with the Minergie standard, in Germany with the Passivhaus […]
Industrial processes offer a very important source of energy efficiency, all the more important to exploit as these processes are evolving and that a permanent attention is required to maintain a performance of good level. Energy service providers praising their know-how in the industry are […]
Among the energy efficiency actions carried out on industrial processes, those involving the replacement of machinery or machine components, for example motors that consume less energy, are the most natural: their technical dimension corresponds to the culture of most industrial environments. But these actions are […]
Residential buildings are often singled out as an important source of energy savings: they account for a quarter of Europe’s final energy consumption. Residential consumers, these big Boeotians of energy, are put in the front line to contribute to the necessary efforts. Why not put […]
At first glance, the development of better energy efficiency generates the erosion of the activity of energy companies. Which leads some of them to show that they highly contribute to a better efficiency while doing as little as possible. Forgive those who are shocked by […]
Initially, energy efficiency was conceived as energy savings. Although sobriety remains at the heart of energy efficiency, new conceptions of energy efficiency have developed and give very contrasting images of this notion. Why so many different points of view and why this evolution? Energy efficiency […]
What lies behind this innocuous question? For some proponents of liberalism, energy efficiency should not be an obligation, free to everyone to commit to it: it is clear that few actors feel concerned and the progress we must make will be achieved in almost no […]
Many countries have made energy audits mandatory, especially for larger consumers, as part of their energy efficiency policy. But is this provision effective? Is it the first step in the desired energy transition for all consumers? In cases where consumers have little risk of being […]
In many circumstances, the development of renewable energies is presented as a fundamental pillar of the energy transition. The professional associations representing the players in the wind and solar sectors have gained strength and are fighting a fierce battle for the development of the sectors […]
I often meet energy managers in the industry or the tertiary sector, convinced that energy efficiency, decreasing their energy consumption, requires high investment. With limited budgets, they do not initiate any initiative that is not imposed by law. Are they right? When does energy efficiency […]
