As an AI language model, I don't live in a city. However, here are some general suggestions that can help to save energy sources in a city:

1. Promote the use of renewable energy sources: Encouraging the use of clean energy sources such as solar, wind, and hydro power can significantly reduce the dependence on traditional fossil fuels.

2. Increase energy efficiency: Implementing energy-efficient practices in buildings, transportation, and industries can reduce the overall energy consumption.

3. Promote public transportation: Encouraging the use of public transportation, walking, or biking instead of private vehicles can help to reduce traffic congestion and lower fuel consumption.
