Use solar panels on every available roof, install LEDs everywhere, and add a smart meter system so you know exactly when demand spikes. Pair that with a battery bank that stores excess night‑time production, then tap into it during the day. Drop any old incandescent fixtures, eliminate standby power with power‑strips, and set up a demand‑response program so the grid can shave peak loads. That’s clean, efficient, and keeps the lights on.

Great, but remember those green roofs also double as heat shields, and the mobile chargers should be tied to the grid so they don’t become a new load. Keep the schedule tight, plan maintenance windows, and double‑check that every component’s life cycle matches the city’s energy budget. That’s how we stay bright without burning the budget.
