Energy conservation?
“Damned green electricity!”

Purpose
1). test the effectiveness of a combination of interventions: tailored information,
feedback and goal setting
2). examine why this combination was(in)effective
underlying determinants: knowledge

Household energy use
Direct energy use Energy use related to gas, electricity and fuel use
• thermostat setting • showering time
Indirect energy use Energy use related related to the production, consumption and disposal of goods
• eating meat • car use for distances shorter than 5 km

Interventions
Information 1). about energy problems 2). about energy saving measures (‘tailored’)
• Lower thermostat setting• Reduce showering time• Eat less meat• Reduce amount of waste
Increase of knowledge

Interventions
Goal settingProvide households with a reference point
Individual goal of 5%Group goal (inhabitants of Groningen) of 5%

Interventions
Feedback about energy savings Insight into (changes in) energy use
• individual feedback: own performance• group feedback: own performance compared to performance of the group of participants

Outline
Longitudinal study: 1 before the intervention (pre-test)2 after the intervention (after 2 and 5 months)
Design1). Tailored information, goal setting (5%), individual feedback (N = 62)2). Tailored information, (group) goal setting (5%), individual feedback, group feedback (N = 61)3). Control group (N = 52)

Determinants: knowledge
What is more energy efficient: cooking on a gas stove or on an electric one?
Experimental 75.4%Control 60.0 %
What uses more energy: A family of four driving 16,000 km a year of flying to the west-coast of the U.S.?
Experimental 74.4%Control 56.4%

Scientific implications
• combination of tailored information, goal setting and feedback seems effective
• educate people on indirect energy use(knowledge)
• Internet a promising medium for behavioral change
