Share of electricity production from renewables, 2023

While the Energy Institute (EI) provides primary energy (not just electricity) consumption data and it provides a longer time-series (dating back to 1965) than Ember (which only dates back to 1990), EI does not provide data for all countries or for all sources of

A comprehensive review of international renewable energy growth

The global energy situation is at a crucial juncture, characterized by a paradigm shift from fossil fuel reliance to cleaner, more sustainable energy sources [125]. This transition is driven by the pressing need to address climate change and the increasing economic viability of renewable energy sources.
