+## Data Quality Notes
+
+- Canonical time field: `year`.
+- Missing values are preserved rather than silently imputed.
+- Column names are standardized for machine use; source meanings are preserved where known.
+- Always confirm source methodology, units, and collection definitions before policy, production, or redistribution-sensitive use.

+- Converted the source table to Parquet for efficient analytics and ML workflows.
+- Added or preserved source provenance columns where available.
+- Standardized README metadata, dataset loading configuration, schema documentation, and citation format.
+- Preserved source-reported values without analytical imputation.
+
+## Suggested Analyses
+
+- Track supply or price trends
+- Compare energy sources
+- Join with population, industry, or emissions data
+- Build time-series views and period-over-period comparisons
+- Pivot to geography x period or indicator x period matrices
+- Check missingness before modeling
+- Use `country_iso3` as the safest geography join key when present
