Which of the following strategies best exemplifies the integration of renewable energy in urban planning while enhancing public transportation systems for sustainable urban development?

A city could build a large solar‑powered transit hub that supplies electricity for electric buses and trains, using the generated power to run the vehicles and charge batteries during the day. By placing the hub on a former parking lot, the city frees up parking space for green roofs, parks, or bike lanes, encouraging people to walk or cycle instead of driving. The hub’s design would include solar panels on the roof and ground‑mounted panels that also shade the surrounding streets, reducing heat islands and improving air quality. This combined approach shows how renewable energy can be woven directly into the fabric of urban transport, making the city cleaner, quieter, and more livable.
