Dartmouth Leads & Hanover Supports
Anyone driving through Hanover this summer has surely noticed the construction along East Wheelock, especially the once very deep and huge holes in front of the New Hampshire and Topliff dorms. “It looks like the College is building a subway system,” my husband commented.
Prominently displayed signs suggest otherwise. “Turning the corner from steam to hot water,” says one. “In the trenches to reach our goal,” says another. This construction is the initial stage of a $500m effort by Dartmouth to decarbonize.
Decarbonizing Concrete
Most people don’t realize that concrete accounts for 7 percent of all greenhouse emissions. It does so in two ways. First, the chemical transformation of limestone into cement, the main ingredient in most concrete, emits carbon dioxide. Second, this chemical process requires a very hot kiln, almost always using fuel that emits carbon dioxide. This is bad news given how widely concrete is used in our buildings and infrastructure. The good news is there are a growing number of ways to significantly reduce its carbon emissions and even use new mixtures of concrete to store carbon removed from the atmosphere.
Sustainable Hanover’s 15th Anniversary Celebration!
Hanover’s July 4th Independence Day Parade provided the perfect opportunity for the Sustainable Hanover Committee to celebrate the accomplishments achieved over the past 15 years.
Yard Sale 2024!
For the 13th year, dozens of local residents, having paid a small fee, gathered in the Dewey Lot to sell their excess stuff. In spite of an ominous weather forecast, the weather stayed fine. Many wonderful volunteers came together to help throughout the month, the few days before and especially on the big day.
Window Dressers Returns!
For the fourth year, Sustainable Hanover and the Norwich Energy Committee are collaborating with the Maine-based nonprofit, Window Dressers (www.windowdressers.org) to make window inserts for Norwich and Hanover residents. The inserts are easy to install, remove and reuse. They let light in, keep drafts out, and reduce heating costs (on average, about 10 gallons of heating fuel per insert per year).
