Whether it’s to shrink their carbon footprint or boost their bank balance, few consumers will dispute the need for decreased energy use. Some steps are relatively easy—switching off lights, or going easy on the climate control. But for real resource management, households need to know exactly how much they’re using. To help them out, companies all over the world are launching smart energy monitoring devices and systems. A few examples we’ve spotted recently:
Promoting shorter showers, Efergy’s Shower Time tracks how much water is used when showering. It comes with a calibration bag to determine how long a specific showerhead takes to run through one liter of water. That number is then saved in the timer’s memory, along with the maximum amount of water someone would like to use. During a shower, the timer indicates how much water has been used so far, and sets off an alarm when it’s time to turn off the tap.
Combining hard data with an appealing interface, the Tendril Vision is a one-stop dashboard for household energy management. It not only lets users review their own current and historical energy consumption, but also that of their neighbourhood. It displays real-time pricing information, alerts users of upcoming price changes, and helps automate routine tasks to circumvent peak load times. Designed by IDEO, the system presents all of this complex information through a simple and elegant interface on a touchscreen display, developed to make energy management part of a household’s daily routine.
Getting kids in on the action, Tio is a light switch ghost that shows children how much energy they’re using. Tio starts off green and happy, and becomes red and angry if lights are left on too long. Information from the light switch is sent to a computer program that allows children and watchful parents to track their lighting use over a period of time. Besides reminding kids to turn off lights, the device is also a playful way of making them aware of the need for energy conservation. The concept was created by Tim Holley, a British designer based in Germany.
Like the colour-changing ghost, the Power Aware cord relies on ambient visual cues to remind consumers of their energy consumption.
