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

The regions that consume the most are in the south of France. Several towns in Occitania are on the podium. We explain why.

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

In fact, according to the collection of data on energy expenditure by the ORE agency (Operadores de Redes de Energia) and Enedis and on the population, by INSEE, it is possible to identify the territories where we consume more electricity.

Knowing that electricity consumption per capita amounts to 2,223 kWh per year and that the residential sector represented 36% of total electricity consumption in 2019, as reported on the site data.gouv.fr.

The ranking of the cities that consume the most


In the top 10 of the cities of France (with more than 50,000 inhabitants) that consume the most, three are in Occitanie. The average per capita consumption established.

  • 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. Hyeres 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 ranks 19th with 2.11 MWh, perpignan in 25 with 2.01 MWh and Toulouse 30 with 1.97 MWh.

Montpelier in position 37 (with 1.88 MWh) it surpasses Paris, which is in position 41 with 1.82 MWh.

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

Ranking of the cities that consume the least

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

  • Creteil 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 green 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 large cities, consumption in Rennes is 1.38 MWh per inhabitant and in Mulhouse 1.41 MWh.

The reasons for such a discrepancy.

But why do the southern regions, which are the least heated in winter, occupy the first position? At first glance this does not seem logical but certain elements can provide the explanation.

Heating mode: homes located in the north of France would be more equipped with heating that uses fossil fuels such as gas, oil, wood than with electric heaters compared to the south.

The quality of home insulation: The thermal insulation of the house is a crucial point in energy consumption. The famous energy strainers consume a lot of electricity.

The regions located further north and, therefore, colder and more humid in winter would be better insulated and, therefore, would consume less energy.

Thermosensitivity: the variations of the thermometer provoke in France an increase of the heating. That is, when temperatures drop, consumers tend to raise the thermostat by 1 degree. The difference between outside and inside temperature is widening

The air conditioning: Electricity consumption due to air conditioning is far from negligible. So if winter temperatures are lower in the south, summer temperatures are higher and the use of air conditioning to cool your home is necessarily more frequent.
