Any urban system relies on energy to support its development, enable its operations, and shape its environmental impact. Energy in an advanced city is more than just the supply of fuel or electricity. The city’s operational resilience, economic vibrancy, and environmental stewardship are all determined by its intricately linked system of supply, efficiency, diversity, and integrated technology. The advanced city concept views energy as a strategic asset that requires careful, creative, and forward-thinking management rather than just a resource.
