Data_Weighted Material Intensity by Energy Technology

The dataset contains critical information on various materials used in energy technologies. Here's a brief scientific description of the data:

Material: The name of the material under consideration (e.g., aluminum, copper, concrete, uranium).
Raw Intensity (I_brut): The unweighted quantity of the material used in energy technologies. This is the baseline value before any adjustment for material rarity.
Scarcity Factor (F_rarété): This factor represents the geological scarcity of the material, where a lower value indicates a rarer material.
Weighted Intensity (I_matériau): The final result that quantifies the relative importance of the material after adjusting for its scarcity, calculated using a logarithmic formula. The higher this value, the more critical the material is for a given technology.
Calculated Intensity: The recalculated weighted intensity based on the formula

Each material is assessed in terms of its raw usage, geological rarity, and the resultant weighted intensity, allowing for a comparative analysis of their importance in the energy transition.
