I've heard that a lot of people are switching to green energy, but I don't know what that means. Can you explain?

Green energy is energy produced from renewable sources such as solar, wind, and hydro power. It's considered clean because it doesn't produce pollution or greenhouse gases like fossil fuels do. Renewable energy is becoming more popular for many reasons, including the fact that it's sustainable and can help reduce our dependence on fossil fuels.
