Preface Green Electricity 25 Green Technologies That Will Electrify Your Future:
Tuesday, May 15, 2030: The sun has just crept into the morning sky as the alarm clock in your electric CD player clicks on. Music fills your bedroom. Electric circuits automatically click on to warm your floor, heat water for your shower, and power the toaster for your morning waffle. It sounds just like today, right? Wrong! It may seem the same inside your house. But outside it’s a new and wondrous science fiction–like world of electric green energy technologies.
Your roof is now an electric power plant supplying advanced photovoltaic energy not only to your house, but also to sell back to the local utility company. No longer do the utility wires (called the “grid”) snake out from smoke-belching power plants surrounded by giant mounds of coal. A nonpolluting microwave receiver dish that catches energy beamed down from orbiting space collectors and converts it into electricity has replaced them. Or maybe your utility company will create its own fist-sized sun, using fusion energy that can convert a cup of water into enough electricity to power a city. As you stretch and rise from bed, you find that the electricity meter outside your house (part of the new Smart Grid) has sent you a text message that your clothes dryer is using more energy than it used to and likely needs repair. It also suggests that the electric rates for your water heater would be lower if you were to get up a bit earlier and shower before 7:00 AM.
Electricity may still look the same and work the same. (Plug something into a wall socket and you get electricity—as much as you want, any time you want. Flip a switch and electricity obediently goes to work—exactly where you want it to go and to do exactly what you want it to. Shove in a new battery, and the electricity hiding inside dutifully makes your portable music play all day.) But the way that electricity is created and delivered to your wall sockets does not. That part of the electricity story will look very different.
