It seems that we are moving ever closer to the home of tomorrow that we were promised in those Tom & Jerry cartoons (remember those?). Search giant Google (NASDAQ: GOOG) announced that it will enter into the burgeoning "smart grid" business, which will help reduce electrical energy consumption. How will the technology work? Well, GOOG has developed a free service called PowerMeter, which consumers can use to track energy usage while it is being consumed in their homes or businesses. Don't worry, this isn't some Big Brother situation, GOOG is not becoming the all-powerful Oz here. According to the head of GOOG's philanthropy arm (yes, they have one), the technology will "depend on a whole ecosystem of utilities, device makers and policies that would allow consumers to have detailed access to their home energy use."
