The Clean Tech Revolution is an effort to make the world a cleaner and better place to live. It involves using technology to create new ways to generate energy, and to make it better for the environment. For example, solar power generates electricity from the sun, and wind turbines capture the power of the wind to create electricity. By using these clean sources of energy, people can generate electricity without having to use polluting fossil fuels like coal and oil. This reduces pollution and helps protect the environment.
