Americans are generally in the dark when it comes to the most efficient ways to save energy, Columbia University researchers say.
The largest group, nearly 20%, said turning off lights was the best approach. This is an action that affects energy budgets relatively little, researchers say.
In general, the survey author says, people tend to believe in what she calls curtailment. “That is, keeping the same behavior, but doing less of it,” Shahzeen Attari of Columbia University’s Earth Institute said. “But switching to efficient technologies generally allows you to maintain your behavior, and save a great deal more energy.”
As an example, she cited high-efficiency light bulbs that can be kept on all the time and still save more than minimizing the use of low-efficiency ones.
People typically are willing to take one or two actions to address a perceived problem, Attari says, but after that they start to believe they have done all they can.
“Of course we should be doing everything we can. But if we’re going to do just one or two things, we should focus on the big energy-saving behaviors,” Attari said. “People are still not aware of what the big savers are.”
