Energy infrastructure
Clean, renewable energy sources make cities healthier, self-reliant, and boost local economies. Energy conservation is the easiest way to save money and protect the environment.
To reduce your city’s carbon footprint and build energy independence, focus on both energy sources and consumers. Cities should consider 4 factors for energy systems:
- potential sources (including decentralized and renewable strategies)
- environmental impacts
- affordability
- reliability of centralized vs. decentralized sources
Local governments can lead by reducing energy use in government buildings and public utilities. Cities can also shape energy demand through policies and programs and promote renewable energy systems with incentives.
