Many Americans still clueless on how to save energy: Study

Washington, August 18 (ANI): A new survey of Americans in 34 states has found that many people believe they can save energy with small behaviour changes that actually achieve very little, and severely underestimate the major effects of switching to efficient, currently available technologies.

The largest group, nearly 20 percent, cited turning off lights as the best approach-an action that affects energy budgets relatively little. Very few cited buying decisions that experts say would cut U.S. energy consumption dramatically, such as more efficient cars (cited by only 2.8 percent), more efficient appliances (cited by 3.2 percent) or weatherizing homes (cited by 2.1 percent).

Lead author Shahzeen Attari, a postdoctoral fellow at Columbia University's Earth Institute and the university's Center for Research on Environmental Decisions, said multiple factors probably are driving the misperceptions.

"When people think of themselves, they may tend to think of what they can do that is cheap and easy at the moment," she said.

Many side factors may complicate people's perceptions. For instance, those who identified themselves in the survey as pro-environment tended to have more accurate perceptions.

But people who engaged in more energy-conserving behaviours were actually less accurate-possibly a reflection of unrealistic optimism about the actions they personally were choosing to take.

The study appears in this week's Proceedings of the National Academy of Sciences. (ANI)
