Many investors are asking me to talk about alternative energy. Sometimes, people request that I write about wind, solar or "electric" opportunities. Others just ask for a recommendation on the biggest, baddest, "greenest" corporation on the NYSE or NASDAQ.

Yet the largest companies are not "largely" responsible for the future of energy resources. It is the smaller and mid-sized companies that are actually forging new ground in cleaner exploration and greener choices. What's more, many of the brightest bulbs are headquartered in foreign countries...

there's one exchange-traded fund that's dedicated to the improvement/enhancement of existing energy technologies. The WilderHill Progressive Energy Fund (PUW) tracks a group of companies that work towards transitional solutions; that is, these are companies working towards "leanness" and greater efficiency in the use of fossil fuels.

PUW is a mixture of long-standing companies and newbies to the field. Still, as much as 80% of the allocation is to small- and mid-cap listings.

And while I didn't mention it in the title, one source of energy still has a future... both in the United States and around the world; specifically, nuclear energy still accounts for 20% of U.S. electricity, while other countries seek new plants for their own purposes...

In fact, there are quite a few profitable companies in uranium mining and plant infrastructure. The Market Vectors Global Nuclear Energy Fund (NLR) is weighted equally across large, medium and small sized participants. Moreover, the exchange-traded fund has garnered a great deal of interest out of the gate.
