Urban planning is experiencing a transformative shift as cities worldwide prioritize renewable energy integration. This emerging practice seeks to create more sustainable, resilient, and livable urban environments by weaving clean energy solutions into the fabric of city growth and redevelopment. Combining holistic spatial design with advanced energy strategies, urban planners are now at the forefront of climate action, shaping cities where renewable sources like solar, wind, and geothermal are the norm rather than the exception. The integration of renewables fundamentally changes how neighborhoods are designed, infrastructure is developed, and communities coexist with their environment, setting the stage for a more sustainable future.
