Principles that Guide Sustainability in Urban Energy Systems[82]

1. Efficiency: reduce the required energy input for a given service.
2. Energy optimization: avoid the use of high-quality energy in low-quality applications.
3. Heat management: exploit all feasible thermal energy.
4. Waste reduction: exploit all available resources (e.g. landfill gas, gas pressure drops, and municipal, agricultural, industrial and forestry wastes).
5. Renewable resources: make use of local biomass, geothermal, hydro, solar and wind energy.
6. Strategic use of grids: optimize the use of energy within the grid.
