Americans are saving energy because they don’t go outside as much anymore, researchers say. It’s a plus for the environment, though in another light (no pun intended), it’s just sad.
In 2012, Americans spent an extra eight days at home compared to 2003, according to the American Time Use Surveys. Being at home means using more energy by keeping the lights on and watching TV. But it also means less travel, and it means that fewer people are outside operating offices and stores. So overall in 2012, we saved 1,700 trillion British thermal units (BTU) of heat, or 1.8 percent of the national total, according to an analysis published today in the journal Joule. That’s about how much energy Kentucky produced in all of 2015.
