I've been writing about the smart grid and its potential since before I joined AltEnergyStocks, in 2007, although at the time, I wasn't using the term: I mostly called it "Smart Metering." Now, Smart Grid is a central part of federal stimulus plans, and the term is firmly ensconced in the popular lexicon. GE even created a Super Bowl ad around the Smart Grid (video).

It was far past time to create a Smart Grid category in our Alternative Energy Stock List, but now we've done it. The companies in the Smart Grid Stock List were previously categorized as both Energy Efficiency Stocks and Electric Grid Stocks. Now, they are in the Smart Grid and Electric Grid categories, but only in the Energy Efficiency category if they also have a more conventional energy efficiency business. The broader Electric Grid category contains both Transmission and Distribution companies, like the ones in my Transmission Shopping List, as well as companies more narrowly focused on the smart grid. A few of the IT companies which have been moving into smart grid (such as IBM, Cisco, and Google) are in the Smart Grid category, but not in Electric Grid.
