Renewable Energy Share Screensaver
The Renewable Energy Share screensaver ranks countries by renewable energy's real share of electricity generation on a live bar board, drawn key-less from the World Bank's open data API. It's free, runs in your browser, and ESC exits.

How the Renewable Energy Share screensaver works
The saver fetches the latest published renewable-electricity-share figures for every country from the World Bank's open data API, with no key required.
Countries rank by real renewable share percentage, with each bar sized to scale.
The board eases smoothly if the ranking shifts on refresh.
Choose how many countries appear on the board at once.
A share is a ratio, not a size
A renewable share answers one question: of the electricity or energy a country produces or uses, what fraction comes from renewable sources? The board draws on the World Bank indicator Renewable electricity output (% of total electricity output), which the World Bank describes as the share of electricity generated by renewable power plants. Its source for the series is the International Energy Agency.
A percentage makes small and large economies easy to compare, but it hides how much energy is behind the fraction. A small country with abundant hydropower can have a very high share of a modest total. The base of the ratio also matters: share of electricity is a different measure from share of total energy, which includes transport, heating and industry, so the two should never be compared directly.
Statistics are published with a delay, and countries do not all report for the same year, so the latest year in a ranking may differ between countries. The ranking tells you the proportion of generation that comes from renewables, not how much electricity is produced, how clean the remainder is, or how quickly the system is changing.
A worked example
You'll see countries with abundant hydro or geothermal resources often leading — real published shares from the World Bank's own dataset, not modeled estimates.
Settings & tips
- Countries shown sets how many bars appear.
- Accent recolours the bars.
- This is distinct from the site's UK-specific Grid Mix, Duck Curve and Wind Farm Output savers — a global country comparison instead.
Frequently asked questions
- What counts as renewable?
- The World Bank's real published figures cover hydro, solar, wind, geothermal and biomass electricity generation.
- Is a key needed?
- No — the World Bank's open data API is free and key-less.
- How current are the figures?
- As current as each country's latest published World Bank data.
- Is it free?
- Yes — free, no download, in your browser.
- Where does the renewable share data come from?
- The World Bank publishes it as the indicator Renewable electricity output (% of total electricity output), with the International Energy Agency as the source.
- Is electricity share the same as total energy share?
- No. Electricity share counts only power generation. Total energy also includes transport, heating and industry, so the two measures give different percentages.
- Does a high share mean low emissions?
- Not automatically. A share says what fraction of generation is renewable, not how much is generated or how the rest is produced.
