Cities run on energy, accounting for about 75% of global energy consumption. Sustainable energy allows cities to power development while reducing adverse environmental effects. They can save energy in all sectors, including transport, building, street lighting, and agriculture. 

Renewable energy is one of the strategies for sustainable energy use. Cities should intensify efforts to leverage solar, wind, hydro, and biomass to produce clean and sustainable energy. That would help cut back on fossil fuel emissions significantly.

Energy-efficient buildings also offer opportunities to cut back energy use, covering the construction phase and its operational life cycle. So, builders should use eco-friendly construction materials and techniques that allow natural thermal regulation and lighting.
