Electricity is the lifeblood of computing, but it might as well be magic, the plug socket a wand and the on/off switch an incantation.
What do you really know about it? It hurts when you touch it, and without it, our code spells don't work. That's about it.
We'll start from the place we should always start, the beginning. How is it made? How is it transported? How is it bought and sold? How is it cooked into a tasty meal for your computer? Finally, how does a CPU use electricity to cast your code spell into reality?
By understanding electricity you'll understand what makes an application and architecture Green, you'll understand how to build applications that use electricity efficiently and the commercial and competitive advantages that Green applications bring you over their Grey inefficient &is more costly counterparts.
