The Boston Globe
Looking for a fun diversion on a sunny summer afternoon? If you live in Boston, check out the city’s online solar map, which shows the solar power projects, large and small, that have been installed throughout the city. You’ll be astonished, as I was, to see how many of your workaday neighbors have gone solar — and not just in the city’s urban hipster quarters. The Renew Boston website includes an interactive tool that lets you estimate how much solar potential is on your own roof, and how much money (not to mention greenhouse gas and toxic particulate matter) you could save by making the switch.
