How to read this diagram
Stack reported coal, gas, hydro, wind, solar and nuclear generation in that fixed order. These six categories share TWh units and are not overlapping aggregates. Oil, bioenergy and other sources are omitted: the sum is explicitly a selected-source total, not the country’s full electricity mix. A year with any missing or negative component breaks every band, so no incomplete total is drawn. Straight band edges connect adjacent complete annual observations; no smoothing or replacement of missing values is applied. The vertical axis starts at zero. Each source observation, flag and note is retained separately.
Annual electricity generation from coal.
Generation is electricity produced, distinct from installed capacity and final energy consumption. Source estimates and historical years may be revised.
Values, source flags and notes retain the reviewed snapshot. No new observations are acquired or interpolated.
