Clean energy is energy that produces little or no pollution when used. It comes from natural sources such as sunlight, wind, and water. These energy sources are used to generate electricity and power systems. Clean energy is used by people, industries, and governments.

Clean energy is produced in many places around the world, including solar panels in sunny regions and wind turbines in open areas. It can be used in homes, cities, and large energy systems. Different countries use different types of clean energy.

Clean energy has become more common in modern times, especially in the 21st century. It is part of how energy is produced and used today. Many systems now include clean energy sources alongside other types of energy.
