We rely on electricity mix data from BP as our primary source for two key reasons: BP also provides total energy (not just electricity) consumption data, meaning energy and electricity data is consistent from the same source; and it provides a longer time-series (dating back to 1965) versus only 2000 from Ember.
However, BP does not provide data for all countries. So, where data from BP is available for a given country or year, we rely on it as the primary source. But we supplement this with data from Ember where it's not available.
Our World in Data has converted absolute electricity production by source to the share in the mix by dividing each by the total electricity production.
to share – to copy, distribute and transmit the work
