Self-consumption, whether individual or collective, has been one of the few, if not the only, way to respond to several energy problems, including greening production using wind, solar and even hydro renewable energy and the scourge of energy poverty affecting more than 80 million Europeans. The Intergovernmental Panel on Climate Change (IPCC) and the International Energy Agency (IEA) regularly call for the mass deployment of all available decarbonized technologies, including renewable energy. The sixth report of the IPCC again indicates that climate change is accelerating and intensifying. Not a month or even a week goes by where we don't see it. In line with this urgency, the IEA recommends the massive deployment of all available clean energy technologies, such as renewable energy. (Pierre Jean Coulon)
