The world now has more than 4,500 gigawatts of clean energy. The International Energy Agency (IEA) shared this news in early 2026. Countries all over the world are making more clean electricity than ever before.
Solar energy is growing the fastest. The price of solar panels has dropped by 90 percent in the last ten years. This makes solar power cheap enough for both rich and poor countries.
In Europe, 40 percent of all electricity came from clean sources in 2025. Wind power is very important there. Denmark and the United Kingdom are leaders in wind energy. They have many wind farms near the sea. Strong government support helps clean energy grow across Europe.
In Asia, China has the most solar power in the world. It has built large solar farms in its deserts. India is also building solar farms very quickly. South Korea plans to get 30 percent of its energy from clean sources by 2030. South Korea wants to build more wind farms along its coastline.
In South America, Brazil gets more than 80 percent of its electricity from clean energy. Most of this power comes from rivers and dams. Now, Brazil is also starting to build solar farms.
There are still some problems to solve. Wind and solar power need good weather to work well. Countries need better ways to store this energy. They also need to upgrade their electricity networks. But experts agree that clean energy is growing fast all around the world.
