Ranking of the cities that consume the most electricity: why Occitania is among the bad students

The regions with the highest consumption are in southern France. Several cities in Occitania are on the podium. We explain why.

Electricity consumption in France accounts for a quarter of the energy consumed in France. And the inhabitants who consume the most live mainly in regions where it is hot.

In fact, after collecting data on energy consumption by the ORE agency (Energy Network Operator) and Enedis, and on the population by INSEE, it is possible to identify the areas where we consume the most electricity.

Knowing that electricity consumption per capita is 2,223 kWh per year and that the household sector accounted for 36% of total electricity consumption in 2019, as reported on the data.gouv.fr website.

The ranking of the cities that consume the most


Of the 10 cities with the highest consumption in France (with more than 50,000 inhabitants), three are in Occitania. The determined average per capita consumption.

  • 1. Frejus with 3.15 MWh
  • 2. Cannes with 2.93 MWh
  • 3. Antibes with 2.89 MWh
  • 4. Montauban with 2.85 MWh
  • 5. Narbonne with 2.77 MWh
  • 6. Grasse with 2.68 MWh
  • 7. Hyères with 2.59 MWh
  • 8. Arles with 2.51 MWh
  • 9. Béziers with 2.50 MWh
  • 10. Aix en Provence with 2.46 MWh

Nimes takes 19th place with 2.11 MWh, Perpignan in 25th with 2.01 MWh and toulouse 30th with 1.97 MWh.

Montpellier in 37th place (with 1.88 MWh) ahead of Paris, which is in 41st place with 1.82 MWh.

In large cities, consumption is 2.21 MWh per inhabitant in Bordeaux and 2.12 MWh in Nice.

Ranking of the cities that consume the least

In the top 10 cities in France (with more than 50,000 inhabitants) that consume the least.

  • Cre part with 1.09 MWh
  • Bobigny with 1.17 MWh
  • Aubervilliers with 1.20 MWh
  • Belfort with 1.20 MWh
  • Nanterre with 1.21 MWh
  • Teal with 1.26 MWh
  • Venissieux with 1.28 MWh
  • Epinay-sur-Seine with 1.29 MWh
  • Saint-Étienne with 1.34 MWh
  • Aulnay-sur-Bois with 1.35 MWh

In the big cities, consumption is 1.38 MWh per inhabitant in Rennes and 1.41 MWh in Mulhouse.

The reasons for such a discrepancy

But why are the southern regions, which heat up the least in winter, in pole position? At first glance, this doesn’t seem logical, but certain elements can provide the explanation.

Heating mode: Households in the north of France would be better equipped with heating using fossil fuels such as gas, oil, wood than with electric heating compared to the south.

The quality of the insulation of the apartments: The thermal insulation of homes is a crucial point in terms of energy consumption. The famous energy sieves consume a lot of electricity.

The regions further north and therefore colder and wetter in winter would be better insulated and therefore less energy intensive.

heat sensitivity: the fluctuations of the thermometer lead to an increase in warming in France. That means when temperatures drop, consumers tend to raise their thermostat by 1 degree. The difference between outside and inside temperature increases

The air conditioner : The power consumption of the air conditioning is by no means negligible. So when winter temperatures are lower in the south, summer temperatures are higher and the use of air conditioning to cool your home is bound to be more common.
