"In Boston, decisions on everything from street lighting to energy retrofits to recycling have rippled far beyond the city’s borders. This happens – and is happening in metros everywhere – because big cities can afford someone with Jim Hunt’s title, because they have the buying power to create demand and lower prices for new technology, and because when cities change, markets change with them. In the world of sustainability, cities have tens of thousands of streetlights, recycling bins, power customers, transit riders, office buildings and homeowners on which everyone else can ride, too."
This is the perfect example on how cities are leading the way on Urban sustainability, supply and demand of sustainable goods make it cheaper for small towns (suburbs) to afford where they normally could not.
Another reason why I can’t wait to work for a city.
