 ## Usage
 
-### Python (full resolution)
-
-```python
-import pandas as pd
-
-df = pd.read_parquet("https://huggingface.co/datasets/daniel-dona/ree-data/resolve/main/ree_peninsula_generation_full.parquet")
-print(df.shape)  # (1931443, 38)
-print(df.columns.tolist())
-```
-
-### Python (via `datasets` library)
-
 ```python
 from datasets import load_dataset
 
 ds = load_dataset("daniel-dona/ree-data")
-print(ds)
-```
-
-### Python (monthly aggregate)
-
-```python
-import pandas as pd
-
-m = pd.read_parquet("https://huggingface.co/datasets/daniel-dona/ree-data/resolve/main/ree_peninsula_generation_monthly.parquet")
-# Track the decline of coal over time
-coal_by_year = m.groupby("year")["car"].mean().reset_index()
-print(coal_by_year)
-```
-
-### DuckDB (direct SQL on parquet)
-
-```sql
-SELECT year, month,
-       AVG(eol)  AS avg_wind,
-       AVG(solFot) AS avg_solar_pv,
-       AVG(car)  AS avg_coal,
-       AVG(nuc)  AS avg_nuclear
-FROM read_parquet('ree_peninsula_generation_full.parquet')
-GROUP BY year, month
-ORDER BY year, month;
 ```

 ## Notes
 
-- **Coal phase-out**: Spain's last coal plants closed in 2025. The `car` column drops to near-zero from mid-2025 onward.
-- **Solar growth**: `solFot` and `solTer` show the rapid expansion of solar from ~2015 onward.
-- **Battery storage**: `bat` and `consBat` become non-trivial from ~2022, reflecting grid-scale battery deployment.
-- **`hid` can be negative**: Negative hydro values indicate net pumping (more energy consumed by pumps than generated by turbines).
-- **`sol` vs `solFot`/`solTer`**: The `sol` column is a legacy aggregate. Prefer `solFot` + `solTer` for accurate solar breakdown.
-- **Updates**: This dataset is a static snapshot as of 2026-05-14. Re-run the source scripts to refresh.
+- **Coal phase-out**: Spain's last coal plants closed in 2025 (`car` → 0 from mid-2025).
