ABSTRACT
This chapter focuses on energy, exploring how zero-carbon cities can become independent of fossil fuels in every sector by switching to renewable energy, absorbing carbon dioxide from the atmosphere by ‘locking it up’ in its fabric, soils and trees, removing by design the need to use energy for many tasks, and reducing existing energy use through energy efficiency. Examining the energy trilemma, the problems faced by coastal cities, the design of new developments, decarbonising existing urban areas, substitutes for natural gas, eliminating short-lived climate emissions, heat networks, energy storage, and which standards to use.
