Check this for a role reversal: Kids could be the ones to school their parents in energy conservation.

In a new study in Nature Energy, researchers at Stanford University found that teaching Girl Scouts in California about energy-saving practices could make them — and their parents — behave better at home. That is, when it comes to turning the lights out.

About 300 girls from 30 troops were involved in the experiment. Researchers separated them into two groups. Over several weeks, one group learned about residential energy-saving behaviors, such as turning off the TV when not in use. The other learned sustainable food and transport behaviors, such as drinking fewer bottled beverages and walking or biking more to troop meetings.
