Energy sufficiency is defined as a way of organising ourselves to better meet energy needs by limiting what we consume - consuming less to do more.
It is now recognised by law as a factor in reducing overall energy consumption to achieve carbon neutrality, by switching to renewable energy.
Contrary to preconceived ideas, many initiatives promote sufficiency as a project that creates value in terms of reducing pollution, preserving nature, making financial savings and strengthening social ties.
When we talk about sufficiency, some people hear "restriction" or "de-growth", which can lead to opposition. But this is not entirely true. In a way, some see it as "intelligent deconsumption".
Considering that doing "less" or "just enough" has benefits may imply moving towards new ways of organising or thinking.

Degrowth is a planned and democratic reduction of production and consumption in rich countries to reduce environmental pressures and inequality, while improving well-being.
Economists who study degrowth agree that it is not possible under the current constraints of our economy. As such, another economic system, which could thrive without being forced to keep growing, is needed.
Environmental pressures are correlated with income. The latest available figures tell us that the richest 10% of individuals are responsible for half of global emissions.
We can make a small portion of growth greener, but only when considering some environmental pressures. For Timothée Parrique we must therefore continue to transform production through eco-efficiency, while investing in sufficiency, and find ways to reduce production and consumption.
