How are they useful?
These tiles are only useful when you use them for what's needed. To make sure energy is not wasted you have to turn off or unplug anything you don't need. It doesn't seem like much to turn off appliances and others, but if you add multiple people doing it together it could reduce the worlds consumption by a lot. You could unplug desktops, TVs, and other appliances.
Where can you get them and what's the cost?
You'd get them at PaveGen System and they are a little expensive, $76 per tile.
