25% of French GNP is affected by weather conditions

In our daily life, our behavior is to a great extent influenced by weather conditions. Here are just a few examples:

• When temperatures are down, the use of heating systems has an impact on national energy suppliers as they need to balance energy production with supply and demand,
• When the wind blows, wind energy production increases dramatically and requires constant adjustments,
• On warm sunny days, the consumption of beer, salads and canned tuna increases significantly,
• At the first ray of sunshine, we tend to wash the car and go to a fun park,
• With the first cold weather, sales of processed cheese and soup increase sharply,
• An organiser of cultural or sports events may decide to insure earnings against rain.

The concentration in a city, a region or a country of these individual behaviours influenced by the weather results in wide fluctuations in consumption that strongly impact producer and distributor activity.

Climate risk is present in a wide range of economic activities:

• Agri-food production,
• Agricultural production (yield, volume),
• Energy production and distribution,
• Solar and wind eco-energy production,
• Sales and the number of visitors numbers at tourists sites, etc.
