The U.S. electric power generating sector may be down, due to the recession and a cooler-than-normal summer across much of the U.S., but it's not out.

Hence, it goes without saying that I'm reiterating my Buy rating for American Electric Power (NYSE: AEP), first recommended on May 4, 2009 at a price of $25.38.

Readers of this space know that one of the preferred sectors is the electric power generation sector.

And it's preferred for a reason that may not be obvious to all. Electricity via win, solar, and nuclear generation is likely to play a large role in energy as climate change reduction, then elimination, becomes a societal goal. Electricity also remains a potential propulsion source for cars, particularly once oil resumes its inevitable clime. And with the above in mind, electric power generator American Electric Power (NYSE: AEP) is worth a review.

The Washington Post reports that pension fund managers representing $1 trillion have petitioned the Securities and Exchange Commission (SEC) to required public companies to disclose the impact of global warming on their business prospects. If the SEC agrees, the change could threaten investors in utility stocks -- which are among the biggest private sources of carbon dioxide emissions that cause global warming.

Here's a list of utility stocks which could be most affected:

• American Electric Power (NYSE: AEP). AEP produced 145.4 million tons of carbon dioxide in 2006. In Europe, where legislation already limits carbon dioxide emissions, allowances for a ton of carbon dioxide sell or 20.5 euros, or about $28.50. So if its 2006 carbon dioxide had been emitted in Europe, AEP would have had to pay over $4 billion.
• Dominion Resources (NYSE: D)
• Dynegy (NYSE: DYN)
• Xcel Energy (NYSE: XEL)

Coal producer, Peabody Energy Corp. (NYSE: BTU) could also be among those companies affected.
