Description/Classification/Threshold: Experiments with Renewable Energy Taxonomy
This is not renewable energy: Nor is this some clever, Magritte-esque meta-commentary on how it is impossible represent or think about renewable energy separate from the technologies that harness it. No, it is simply an issue of taxonomy: hydropower is only counted as “renewable” some of the time.
