Numeracy vs feel-good
Most people would agree that increasing energy efficiency is a sensible thing to do, both as a cost-saving measure, to conserve limited fossil fuels and to lower climate impacts. But being willing to save energy does not mean one is efficient in doing so: a new study shows that people are bad at estimating how large energy savings are (or, as The Register put it more forcefully, "People have NO BLOODY IDEA about saving energy"). People tended to think that curtailment (e.g. turning off lights, driving less) was more effective than efficiency improvements (e.g. installing better light bulbs or appliances). They tended to overestimate the benefits of small savings like removing cellphone chargers and underestimate the benefits of large savings such as reducing heating. The study authors somewhat predictably concluded that well-designed efforts to improve public understanding of energy savings would be useful. But would they?
