Clean technology is technology that is used in a way that helps reduce the amount of pollution that is created when things are manufactured, produced, or used. So, instead of using polluting technologies, like burning fossil fuels, the technology helps find ways to reduce the amount of pollution. Some clean technologies can even use renewable energy like solar and wind to power things instead of using polluting energy sources. In general, clean technology is a way to help be better to the environment, while still being able to make things and use energy!
