What is this?

The Clean Energy Scoreboard tracks the global energy transition by answering one question: Is clean energy winning?

We take electricity generation data from every country in the world and present it as a scoreboard — clean energy vs. fossil fuels. No jargon, no downloads, no paywalls. Just the score.

Data source

All data comes from Ember, an independent energy think tank. Ember compiles electricity generation data from official government sources across 215 countries and territories.

Ember's data is licensed under Creative Commons Attribution 4.0 (CC-BY-4.0). We are required to credit Ember as the source of this data, and we do so gladly — their work makes this scoreboard possible.

What counts as “clean energy”?

We follow Ember's standard definition. Clean energy includes:

• Solar
• Wind
• Hydro
• Nuclear
• Bioenergy
• Other renewables

Fossil fuels (coal, gas, oil) are everything else. The “clean energy share” is the percentage of total electricity generation that comes from clean sources.

Note: The inclusion of nuclear energy as “clean” follows Ember's methodology and reflects its low-carbon generation profile. We recognize this is a topic of debate and present it transparently.

Methodology

Update cadence: Data is refreshed twice per month, matching Ember's publication schedule (first and third week of each month).

Momentum: The year-over-year change in clean energy share (in percentage points). A country with 50% clean share last year and 53% this year has +3.0pp momentum.

Leaderboard: Countries are ranked by clean energy share of electricity generation. Countries with less than 1 TWh of total generation are excluded to avoid statistical noise from very small economies.

Caching: Pages are statically generated and revalidated every 24 hours. Data may be up to one day behind the latest Supabase sync.

Scope — electricity only: All data covers electricity generation only. It does not include energy used for heating, transport, cooking, or industrial processes. A country's clean electricity share may differ significantly from its overall clean energy share.

Low electricity access: Some countries (particularly in Sub-Saharan Africa and parts of Southeast Asia) have very low rates of electricity access. These countries may show high clean energy shares because their small grids are often hydro-dominated, but this does not reflect the energy reality for most of their population. Country pages for these nations include a context badge.
