Seven countries around the world have crossed a remarkable threshold: Albania, Bhutan, Nepal, Paraguay, Iceland, Ethiopia, and the Democratic Republic of Congo now generate more than 99.7% of their electricity from renewable energy sources. Data from the International Energy Agency and the International Renewable Energy Agency confirm that geothermal, hydro, solar, and wind power together supply nearly all of the electricity these nations use — not as a future target, but as a present reality.
At a glance
- Renewable electricity share: All seven countries exceed 99.7% renewable electricity generation, driven primarily by hydropower resources.
- Global momentum: Around 40 other countries now produce at least half their consumed electricity from renewables, including 11 in Europe.
- Clean energy technology: Stanford University’s Professor Mark Jacobson argues no miracle technologies are needed — only the focused deployment of wind, water, and solar at scale.
What these countries have in common
Most of the seven nations share one advantage: geography. Nepal and Bhutan sit in the Himalayas, where fast-moving rivers power massive hydroelectric systems. Paraguay draws almost entirely on the Itaipú Dam, one of the world’s largest hydropower plants, which it shares with Brazil. Iceland sits atop volcanic geology that makes geothermal energy abundant and cheap. Albania, Ethiopia, and the DRC are similarly rich in river systems that hydropower infrastructure has been built around over decades.
That geographical luck matters — but it doesn’t diminish the achievement. These countries made deliberate policy and infrastructure choices to build their economies around clean power, and many are now among the lowest per-capita carbon emitters for electricity in the world.
A wider global shift
The seven countries are the sharpest edge of a much broader trend. According to IRENA data, roughly 40 nations now source at least half their electricity from renewables. Eleven of those are in Europe, where wind and solar capacity has expanded rapidly over the past decade.
In the U.K., renewable technologies provided around 41.5% of electricity in 2022 C.E. Germany has achieved short periods of 100% renewable-generated electricity during high-wind and high-solar days. These episodes are still temporary, but they point toward what sustained national grids may look like within a generation.
The global share of electricity from renewables has climbed steadily, with solar alone growing faster than almost any energy technology in history. The cost of utility-scale solar has fallen more than 90% since 2010 C.E., making it competitive with fossil fuels in most markets without subsidy.
No miracles required
“We don’t need miracle technologies,” Professor Mark Jacobson of Stanford University has said. His research group has mapped pathways for 139 countries to reach 100% wind, water, and solar power — using technology that already exists at commercial scale. The prescription is straightforward: electrify as much of the economy as possible, then power that electricity with clean sources.
That framing matters because it shifts the debate. The question is no longer whether it is technically possible. It is whether the pace of deployment matches the urgency of the climate challenge.
The full picture
The seven countries’ success does come with honest caveats. Most of them rely heavily on large hydropower, which has its own environmental costs — including disrupted river ecosystems, displaced communities, and vulnerability to drought as climate change alters rainfall patterns. Several of the DRC’s and Ethiopia’s dam projects have drawn criticism from environmental and human rights groups.
Scaling what these countries have done to larger, more complex economies will also require solutions to grid storage and transmission that are still maturing. But as a proof of concept — that a modern society can run on clean power — they are hard to argue with.
The data shows the floor rising. What was a handful of countries a decade ago is now seven confirmed cases and dozens more on the way. The IEA confirmed in 2023 C.E. that renewables became the largest single source of electricity generation in Europe. Globally, the share keeps climbing.
Seven countries are already living in the energy future that most of the world is still planning for.
