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.

One of Obama's top priorities is making our nation energy independent with alternative energy. A barrel of oil trades in the $60s and has been coming down for awhile. But over time, energy will probably rise. If our country can build energy independence, it creates jobs, helps our national security and stops the dramatic wealth transfer to potential enemies of our country.

If Obama does what he promises, there will be more investments in the alternative energy field. Instead of trying to pick the best stocks and learn all about these companies, you can own one stock, an ETF (exchange traded fund) that is a basket of the top companies in this sector.

The Market Vectors Global Alternative Energy ETF (NYSE: GEX) is a low cost way to play alternative energy. GEX is built around an index developed by Ardour Global which includes companies that generate power through eco friendly and non-traditional sources. It started the year at $60.45 and has corrected down to $23.27 today.

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."
