Scouting for energy savings



今回Hilary Boudetたちは、カリフォルニア州北部のジュニアガールスカウト団30団体(平均年齢9.6歳)に、家庭での省エネ行動と食品や交通手段を決定する際の省エネ行動をそれぞれ促進するように設計した2種の教育的介入の1つを割り当てた。その結果、夜に電源コードを抜いたり冷水で洗濯するといった省エネ行動の子供の自己報告が、試行後7か月以上にわたって増えたことが分かった。さらに、両親が自己報告した家庭の省エネ行動にも、8か月以上にわたって教育的介入が影響を及ぼしたことも示されている。著者たちは、こうした行動の変化によって、家庭での年間エネルギー消費が教育的介入の直後で約3~5%、その後のフォローアップ期間で1~3%削減されると見積もっている。


Girl Scouts and their parents report increased energy-saving behaviours following an intervention aimed at the children, according to a study published online this week in Nature Energy. The study suggests that scaling up similar interventions aimed at Girl Scouts and other youth organizations could help to increase energy savings for many families in the US.

Education and behaviour programmes are increasingly seen as important for raising awareness of energy-saving practices among young people. Studies also indicate that children have an important influence on their parents’ attitudes and behaviours.

Hilary Boudet and colleagues randomly assigned 30 Junior (mean age 9.6 years) Girl Scout troops in northern California to one of two interventions designed to promote energy-saving behaviours either at home or in food and transport decisions. The authors found that the children’s self-reported energy-saving behaviours - such as turning off power strips at night and washing clothes in cold water - increased for more than seven months after the trial. They show the interventions also had an effect on the parents’ self-reported residential energy-saving behaviours for more than eight months. The authors estimate that these behaviour changes represent an annual household energy savings of approximately 3-5% immediately following the intervention and 1-3% at follow-up.

Finally, they note that food and transportation energy-saving behaviours did not increase at follow-up, possibly because these behaviours are constrained by geographic, cultural and economic factors - such as availability of public transport and family eating practices - and may be difficult to change through brief behavioural interventions alone.
