Methodology
Data sources
This report analyses annual power generation and import data for 215 countries from 2000 to 2021, with 2022 data included for 78 countries representing 93% of global power demand. Data is collected from multi-country datasets (EIA, Eurostat, BP) as well as national sources (e.g China data from the National Bureau of Statistics). The latest annual generation data is estimated using monthly generation data. Annual capacity data is collected from GEM, IRENA and WRI. A detailed methodology can be accessed here. All the data can be viewed and downloaded freely from Ember’s website.
