That fan left switched on in another room. Your PC left running after your work or between intervals. Or the lights glowing in rooms you do not use. Global Climate Change may have turned a debate of sorts over the last few years, but consumer masses do not realise that these ignorant waste instances of electricity not just shoot up our electricity bills, but burden our resources greatly too.

Warning Bulb is meant to control that habit of users. It’s a pre-paid electricity card that is controlled by a fuse box. Insert the card into the fuse box and it makes you check your `balance’ of electricty left. Electricity Per Minute is the measure for the remaining amount. In short, it displays how much electricity you are using exactly. The higher your electricity usage, the yellower the bulb connected to this becomes. When you finish the allotted units of power, the W in its centre flickers.

Much like the pre-paid card system on mobile phone services, Warning Bulb is surely a gadget one needs, in the interest of the earth and in their own interest. It has been designed by G-Ye Kim, Young-Duk Song and Yoon-Sun Yang.
