Methodology

The data used on this website comes from a number of sources, listed further down. The process of validating and merging data involves several steps. Validation is mainly done by comparing calculated and listed totals, for each region and worldwide. Data points that do not meet a certain acceptable level of error are discarded. Subsequently an ideal data source is chosen for each region and year. In some cases there is only one source available for the specific region and year. If multiple sources are available, the source which includes the most specific data is chosen. For example, some data sources group certain energy types together, such as Geothermal and Biofuels. In these cases the more specific data point is preferred. To find out which source was used for each data point you can download the combined data further down on this page.

Electricity Generation Data Sources

The main electricity data used on this website comes from IEA, Ember, EIA, the World Bank and BP. The trade data used to calculate net imports comes from Enerdata, IEA and Ember. Data for each region and year is taken from one single source. Here is an overview of the relative use of each data source:
