Data_Weighted Material Intensity by Energy Technology
Description
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 𝐼 material = 𝐼 raw × − log 10 ( 𝐹 scarcity ) I material =I raw ×−log 10 (F scarcity ). 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.

Steps to reproduce
To reproduce this research, others can follow these steps: Gather Data: Use the same or updated versions of the reports from IEA, USGS, and the European Commission to collect data on material usage and scarcity. Assign Scarcity Factors: Extract scarcity factors for each material based on their global distribution. Calculate Intensities: Use the logarithmic formula in the doc to calculate weighted intensities for each material.
