Renewable energy integration involves incorporating sources like solar, wind, and geothermal into the fabric of urban environments. With growing awareness of climate change and the necessity for sustainable urban growth, city planners are increasingly prioritizing energy systems that minimize carbon emissions and support resilient, healthy communities. The proactive inclusion of renewable energy in city planning not only reduces environmental impact but also offers long-term economic benefits, energy independence, and an improved quality of urban life. Through thoughtful design and forward-thinking strategies, cities worldwide can lead the way toward a clean-energy future.
