First off, what is smart grid technology? Smart grid technology allows two-way communication between a home or business and the utility company.

Then you are probably wondering why is there so much interest in smart grid technology now? The key reason is that our electrical transmission system is outmoded and overloaded. Our present system will be unable to handle the increasing demand for electricity for much longer. Take the electric car. If thousands of these cars are on the road next year, we will need the electrical delivery system to power them.

"I'm adding Itron (NSDQ: ITRI) to my diversified portfolio of stocks in the alternative energy space," says Elliott Gue.

In The Energy Strategist he explains, "The firm will benefit from both the HR 2454 bill (a cap-and-trade system designed to reduce U.S. greenhouse gas emissions) and the stimulus bill which included direct subsidies aimed at promoting efficiency and building a more intelligent electric grid.

"Itron is a leading play on energy efficiency and smart grid technologies, a key, near-term component of cutting carbon emissions.

Here are some highlights from this past week's earnings coverage from BloggingStocks:

• Adobe Systems Inc. (NASDAQ: ADBE) Q2 earnings were in line with expectations but sales beat.
• Best Buy Inc. (NYSE: BBY) beat earnings estimates for Q1, but on horrible metrics, sending shares lower.
• Carnival Corp. (NYSE: CCL) lower Q2 earnings beat expectations and previous guidance, boosting shares.
• CarMax Inc. (NYSE: KMX) Q1 profit and sales dropped, but still beat expectations, sending shares higher.
• Discover Financial Services (NYSE: DFS) posted a smaller-than-expected Q2 net loss and shares rose.

"Itron (NASDAQ: ITRI), which is involved in the build-out of smart grids -- has been our radar screen for awhile," says growth stock expert Toby Smith.

In his ChangeWave Investing, he suggests, "As the top supplier of smart meters and meter infrastructure for the electricity industry, Itron is by far the best-positioned company for the smart grid build-out."

"The build-out of smart grids employs technologies that deployed across an energy grid which allow greater efficiency and flexibility during energy distribution and transmission.

"The cool thing about smart grids is that they are capable of isolating and better managing power outages and disruptions, integrating local power generating equipment, and avoiding electricity congestion or bottlenecks.

Analyst downgrades:

Many investors, especially "momentum investors" are passionately obsessed with owning the hot stocks of the market. Momentum stocks tend to be fast-growing, high-margin companies in popular industries. Understandably, these stocks tend to fetch incredible multiples on their earnings.

I don't cover many momentum stocks for BloggingStocks, however here are some that I've spoken about:

• Skyworks Solutions (NASDAQ: SWKS) -- I argued that the company has more upside in its operations which should lead to further upside in the stock.
• DryShips (NASDAQ: DRYS) -- I explained why I think the stock had further upside due to the tremendous strength in drybulk shipping rates recently.
• Dawson Geophysical (NASDAQ: DWSN) -- I rationalized a buy at current levels due to a variety of fundamental and technical factors.

Similarly, I think the fundamental and technical backdrop in Itron (NASDAQ: ITRI) is very interesting and the stock could be a worthy buy presently.

Anyone who hasn't been stuck under a rock in recent years is well aware of the shortage in energy and water resources throughout the world. Itron makes power and water meters alongside analytical software which allows utility companies and other resource providers to find inefficiencies in distribution and consumption. Understandably, these services allow for more efficient consumption and, therefore, waste reduction.

In today's day and age it should be easy to see the value of these products. As the company states on its website, "With that type of detailed information for decision-making, everyone benefits: utilities, customers, regulators, shareholders and, of course, the environment."
