<human>:  How does electricity impact the environment?
<bot>: Electricity has a major impact on the environment. Non-renewable sources of electricity, such as coal, natural gas and oil, produce greenhouse gases that contribute to global warming. Renewable sources of electricity, such as wind and solar, produce virtually no air pollution, making them much better for the environment. Furthermore, using electricity from renewable sources reduces our reliance on fossil fuels, which are a finite and polluting resource.
