The smart grid, which is on its way to the US, promising huge energy savings for the country as a whole, and for individual consumers as well, has the potential to put control of energy use within the hands of the average person. In particular, the smart grid will help any energy user consume energy in low-demand periods, which will save them money and reduce the number of power plants required for the nation as a whole.

But in order to really take advantage of this new energy-efficiency technology, we’re going to need appliances that know how and when to consume energy, otherwise we won’t receive the full value of the grid at home. Today, there are several large manufacturers working on developing smart dishwashers, dryers, microwaves, and more that will save power and power plants.

Whirlpool—a company that’s promised to make all of its appliances “smart” by 2015—finally seems to be putting some legs on its plans, announcing recently that they will be producing 1 million smart clothes dryers (one-quarter of its production) for sale by the end of 2011. For those with variable electricity pricing, Whirlpool believes this innovation could save the average consumer between $20 and $40 annually.

How does it work? The utility’s grid will automatically “tell” the dryer to power down during peak energy-use periods (immediately after normal work hours, for instance). Whirlpool estimates that if all million dryers were to go into standby mode during peak times, it could reduce energy demands equivalent to 6 coal power plants.

In a similar move, GE is in the process of putting plans for smart water heater production into place—technology that should reduce energy use by 50 percent compared to similar heat pumps. The good news is that these new, smarter appliances should not have price points much higher than a comparable ENERGY STAR product.
