International renewable energy alliances are groups of countries from all over the world that join forces to make clean energy, like solar energy, wind energy, and hydroelectric power. They work together to figure out ways to make these kinds of energy available for everyone and to protect the planet. By joining forces, they can share ideas and resources to make sure renewable energy is used in the best possible way and can help to reduce air pollution and global warming. Everyone in the alliance helps to solve the planet's energy problems, and the planet will be better for it!
