DIY Kyoto Wattson
Appliances account for about 24% of total energy consumption in Swedish households. In addition, the total energy consumed by household appliances on standby amounts to the same amount of electricity used by 400 houses for one year. Electricity consumption could be reduced if consumers were informed and reminded about unnecessary use. The Wattson Energy Meter is a product that uses wireless technology to measure and provide information on energy consumption in the home.
Wattson is an example of how a product can convey a message in a clear and educational way. An array of colourful lights indicate current energy use and a numerical display shows the monetary value in real time. The product stores information about energy use for up to four weeks and can be attached to a computer to retrieve a graphic image of consumption over time.
Wattson is not about making consumers feel guilty. It is about making it easier for users to understand their personal impact on the environment and make active choices. Studies show that Wattson can save up to 25% of energy expenditure in the home just by making consumers more aware.
