"Momentum stocks are breaking out again, and it's time to stock up," says Kevin Kennedy in his Coolcat Report. The advisor's latest recommendation is global blue chip energy firm, Sasol Ltd. (NYSE: SSL).

He explains, "When we select among blue chip stocks for our portfolio, we look for such factors as having set a 52-week high in the previous two weeks, as well as a ratio of at least 1.5-to-1 between the price and 52-week low.

"One such stock is Sasol, a global energy company with annual sales of more than $13 billion, headquartered in Johannesburg, South Africa. It is engaged in the commercial production and marketing of chemicals and liquid fuels with a growing interest in oil and gas exploration.

"The company has developed world-leading technology for the commercial production of synthetic fuels and chemicals from low-grade coal, as well as the conversion of natural gas to environment-friendly fuels and chemicals. The stock has advanced 22% in 2007 and is working on its seventh straight month of gains."

What are the best energy investments for long-term investors? To answer this question, I surveyed 20 of the nation's leading financial newsletter advisors to find their current favorite ideas in the energy sector.

Interestingly, the advisors see the best opportunities in areas well beyond traditional oil firms; indeed, no one included in this report chose a major integrated oil company. Rather, the advisors have shown a preference for various oil services sectors, non-oil energy sources, and developing alternative technologies.

Some focus on areas such as deep-sea operations with Diamond Offshore Drilling Inc. (NYSE: DO), Transocean Inc. (NYSE: RIG) and Oceaneering International (NYSE: OII), while others look toward oil shippers such as Nordic American Tanker Shipping (NYSE: NAT) and refiners such as Valero Energy Corp. (NYSE: VLO).

Others chose companies that make specific products needed by the oil & gas industries such as NATCO Group Inc. (NYSE: NTG), which makes a wide range of oil & gas processing systems; Dresser-Rand Group Inc. (NYSE: DRC), a maker of control systems; Gardner Denver Inc. (NYSE: GDI), which makes compressor and fluid transfer systems; Tenaris (NYSE: TS), a maker of pipes and tublar products and Schlumberger Ltd. (NYSE: SLB), the largest and most diversified of the oil services companies.
