If you live in an apartment building with five or more units, you probably use significantly less energy than your friends living in single-family homes.
Maybe you have suspected this, because your apartment is so much tinier than most people’s houses (which is certainly the case for this reporter) and therefore uses less energy. Or perhaps you already pat yourself on the back regularly for being an urbanite who lives efficiently, from taking public transportation and using bike shares to unplugging electronics and community composting.
But something else is also going on. Sure, the average home uses more energy than an apartment because of size. Also, apartments generally have fewer windows and outside walls.
