Our group's task was to research energy monitoring devices and consider whether they were useful in helping to prompt users to conserve energy.
Here are a few examples we found in our research:

| This is an energy monitoring device that gives you instant feedback about your current energy use. The LEDs are used for visual feedback, "cool blue for small amounts of electricity being used; warning red for high energy consumption." These lights attractive and make you want to interact with the object, while the overall design of the object is aesthetically pleasing. The device also records a history of energy use, available for download and view on special software - although this is possible, it is not a particularly user friendly way to give feedback about historical energy consumption as you have to go the extra mile to get that information, it's not simply in your face and grabbing your attention, as it should be in this kind of device. http://www.watthackers.com/wp/10-energy-saving-devices-to-put-your-house-on-a-diet/ |

| This device is an energy monitoring device that records a history of your energy use and compares it to your current energy use. It's called the Energy AWARE Clock - designed much like a normal clock, but it incorporates energy use levels over time on the screen. This way, you can monitor how much overall energy is used at any one time during a 24 hour period. In addition, it shows historical periods behind the current 24 hour period, which gradually fade, encouraging the user to improve on their energy saving over time, therefore we felt it a particularly good example of a helpful energy monitoring device. http://www.tii.se/node/5984 |

| We thought this energy monitoring device was interesting, yet potentially not specific enough to give good feedback to the user about their energy use. The idea is that 'good' energy use (low levels) will grow a healthy plant, whereas 'bad' energy use (high levels) will cause it to wither. The problem is that there's not really any immediate feedback - it's more of a generalised response. It might work better in combination with another, more specific, device. http://www.tii.se/projects/energyplant |
The idea behind this particular energy monitoring device is pretty basic - it records how much energy a particular device consumes. The issue with it is that, as our group decided, it's ugly. There is nothing about this device that would make the user actually want to interact with it. It has a basic LED screen, black and white and is made out of off-white plastic, so is likely to make the user want to hide it. Sure, the intentions might start out well - the user keeps some tedious diary or similar to record power usage.... But to be an effective energy monitoring device, we thought that the device needed to be pretty - pretty = visually attractive = user gets feedback from the product without even realising they are tediously monitoring energy use - otherwise, how long is this resolution going to last? No one wants to do things that aren't fun. Energy monitoring devices should be fun and truly conducive to interaction in order to be really effective in helping users save power. |
Finally, we came up with aspects of energy monitoring devices that we felt were possibilities for a good design of a user interface:
- Sends emails/texts as feedback
- Pretty/visually appealing
- Wireless connectivity - ease of use
- iPhone/smartphone interface
- Touch screens - they look pretty/people want to use them, fun
- Easy to view - colour, nice numbers
- Actual cost [of electricity] - clear feedback
- Sound as warning [of high use] - beep/ringtone
- Keyring, jewellery, watch - readily accessible objects for interface
- Pretty lights
- Uninvasive, small
- Stores energy history
- App to coach you on saving energy
- Reminders of things left on as you leave the house
- Remotely turns off devices
- Affordable
- Positive feedback on how much power you might have saved while out
- Power-saving suggestions
