Who Added the Most Electricity, 2015 to 2025
Between 2015 and 2025, the 94 countries with an Ember generation figure for both years (94% of world generation in 2025) added 7,490 TWh of electricity a year, up 33.2% on 2015. China supplied 4,707 TWh of that, 63% of the increase, followed by India 770 TWh (10%) and the United States 436 TWh (6%). Solar and wind together supplied 4,337 TWh, 58% of the extra electricity, so they covered part of the increase but not all of it. Coal supplied 1,346 TWh (18% of the increase) and gas supplied 1,100 TWh (15% of the increase). Over the shorter window, 2020 to 2025, China supplied 56% of the 4,907 TWh added and solar and wind 61%. Both windows end in 2025, Ember's newest annual year. Data as of 2025, Ember annual statistics.
Countries with a generation total for both 2015 and 2025: 94 in this data, together 94.5% of Ember's World region generation in 2025 and 94.1% in 2015. Countries that lack either year, including those that have not yet reported 2025, are left out, so the pool's totals are below the world totals; the World region rose 7,827 TWh over the same years and the pool accounts for 96% of that. A fuel a country does not report counts as zero. Figures are generation, not consumption.

Questions About Who Added the Most Electricity
Which country added the most electricity between 2015 and 2025?
Across the 94 countries with data for both years, generation rose 7,490 TWh. China supplied 4,707 TWh of that, 63% of the increase, followed by India 770 TWh (10%) and the United States 436 TWh (6%). Figures are Ember annual generation.
Did solar and wind cover all the growth in electricity between 2015 and 2025?
No, only part. Solar and wind together added 4,337 TWh, 58% of the 7,490 TWh rise in generation across the 94 countries with data for both years. Fossil fuels supplied 30% of the rise.
Which country added the most electricity between 2020 and 2025?

Which countries does this comparison cover?
Countries with a generation total for both 2015 and 2025: 94 in this data, together 94.5% of Ember's World region generation in 2025 and 94.1% in 2015. Countries that lack either year, including those that have not yet reported 2025, are left out, so the pool's totals are below the world totals; the World region rose 7,827 TWh over the same years and the pool accounts for 96% of that. A fuel a country does not report counts as zero. Figures are generation, not consumption.
Is this about generation or demand?
Generation. Ember publishes electricity generation by fuel for each country and year, so this page measures how much more electricity was generated. Generation also includes electricity that is exported or lost on the way, so it is close to, but not the same as, demand.
