Citizens and business often waste energy because they do not realise which appliances and lighting use the most energy. An EU-funded project tested in the United Kingdom and Bulgaria is helping to change that – showing consumers reduced energy usage by an average of 8% when provided with an "information dashboard" about their energy use.
The Digital Environment Home Energy Management System (DEHEMS) project shows that when a consumer receives more information about their energy use, and can share and compare this with neighbours and family, they are more likely to change their behaviour. The EU-funded system presents data every 6 seconds through a small digital display. The data can also be displayed in real time via a TV screen, mobile phone, PC or social media app.
