I've been hearing a lot of buzz about green energy lately. What is it, and how can it help the environment?

Green energy is a term used to describe renewable sources of energy such as wind, solar, hydro, biomass, geothermal, and tidal power. These sources are considered "green" because they produce fewer emissions than traditional fossil fuels like oil and natural gas. They also provide an alternative source of energy that doesn't contribute to climate change or air pollution.
