Renewable energy sources, like solar, wind, and hydropower, are naturally replenished and won't run out. For example, the sun will keep shining, and the wind will keep blowing, so we can use them as much as we want without depleting them. Non-renewable energy sources, like coal, oil, and natural gas, are limited. Once they're used up, they can't be replaced in our lifetime.
Renewable energy is important because it helps reduce pollution and fight climate change. Unlike non-renewable sources, which release harmful gases into the atmosphere, renewables produce clean energy. They also provide a sustainable way to meet our energy needs without damaging the environment or running out of resources in the future.
