<human>:  What are the environmental benefits of switching to renewable energy sources?
<bot>: The environmental benefits of switching to renewable energy sources are numerous. Renewable energy sources, such as solar and wind, produce no air pollution, significantly reducing greenhouse gas emissions when compared to burning fossil fuels. Renewable energy sources are also generally more sustainable, using natural resources that are constantly replenished. These sources often have lower water usage and help reduce water pollution, while also reducing the need for hazardous waste disposal. Additionally, renewable energy sources can help reduce the overall dependence on finite resources, such as coal and oil.
