IRENASTAT (©IRENA 2024) offers an extensive compilation of renewable energy statistics, encompassing a diverse array of 18 distinct renewable energy sources, such as Hydropower and Solar. In addition to these individual categories, the dataset includes "Total renewable energy generation" entry, which effectively consolidates the contributions from all 18 sources.
In terms of measurement, the dataset uniformly employs Gigawatt-hours (GWh) as the unit of quantification for electricity generation.
Electricity generation (GWh) is the gross electricity produced by electricity plants, combined heat and power plants (CHP) and distributed generators measured at the output terminals of generation. It includes on-grid and off-grid generation, and it also includes the electricity self-consumed in energy industries; not only the electricity fed into the grid (net electricity production).
