The proven limits of individual efforts and the difficulty of managing collective dynamics make energy transition an extremely challenging task when approached through consumption. Fortunately, technologies can change the game: smart consumption is on the...

As noted in a previous article, the very notion of a responsible consumer faces certain limits. The truth is, significant changes in the energy mix cannot be achieved through the goodwill (or conversely, the guilty...

Energy transition is the changeover from an economy based on high consumption of fossil fuel sources to a more ecology-intensive society. In practical terms, an energy transition policy must provide for energy-saving, optimized generation systems...

It is a paradox: despite huge oil reserves supporting their wealth, Norwegians have become, in a few years, the first users of electric vehicles. These represent 18% of new registrations since the beginning of 2015!...

In February Elon Musk boldly predicted Tesla motors would go where no car company has ever gone before, to a $700 billion market valuation by 2025. To put that in perspective, Apple became the most...

Wind turbine and solar power sources now represent a significant fraction in the electricity generation mix of industrialized countries. How did they achieve such a breakthrough successfully? European countries use differing models, which all show...

In an industrial facility, the key-concept is reliability. It is all the more true in utilities such as electric power companies, since one must be able to trust the electricity provider 24/7, year in, year...

Engine efficiency is the key for automotive CO2 emissions management. While the internal combustion engine (ICE) fuel efficiency still has much room for improvement, what can we do with the environmentally friendly hybrid car? And...

Storing electricity? Some old solutions to this old problem are gaining momentum nowadays, thanks to recent improvements. Among these solutions, using electricity to obtain hydrogen and reconverting it later into energy or heat via fuel...

Rising energy consumption round the world, rarefaction of fossil energy sources, climate change, the necessary reduction of greenhouse gas (GHG) emissions… The development of new and renewable energy sectors, emitting few or zero GHGs has...

The German experience reminds us: energy transition must be progressive and planned for the long term. The first stage in such a debate must be an objective discourse on intermittent energy sources to avoid unrealistic ideas about their potential.

Burning of fossil fuels constitutes the main source today of greenhouse gases and it is also the principal vector of anthropic action on the climate. But the relationship between energy and climate is far more...

The electricity transmission network is the backbone of the electrical system, a key asset in the energy transition. It must both adapt to the means of production and meet consumption needs to ensure a sustainable...

The energy mix can be defined as the distribution of primary energy sources consumed to produce various types of energy used in a given country. For different reasons, running from availability of the resources to...
