"ConocoPhillips (COP) is not only my favorite integrated oil company, it is also on the short-list of my favorite stocks, period," says Nathan Slaughter.

The editor of Street Authority Market Advisor explains, "The company is raking in cash; the integrated oil giant pocketed $2.0 billion in net profits last quarter on $53.2 billion in revenues.

"For all of 2010, earnings soared nearly 160% to $11.4 billion. That percentage gets cut in half when you exclude one-time gains and charges. Still, it's a good time to be a shareholder.

"We have decided to go long in one sector that is in the midst of a rebirth -- the nuclear power industry where we have been bullish now for the last two years," says Steve Christ.

The editor of The Wealth Advisory explains, "While some think the nuclear revival is something new, this is one bandwagon we have been on for years. In recent years, the industry has been slowly rebuilding itself providing investors with a future growth opportunity."

Independent oil/gas company Ultra Petroleum Corp's (UPL) stock has meandered since my June 4, 2009 buy recommendation at a price of $46, but I'm reiterating the call, and investors should view the sideways action as chance to scoop-up shares. Here's why:

Ultra's growth prospects are strong, with three-year reserve replacement rates that are among the best in its class; below-competitor operating expenses represent another UPL advantage. Likely firming, then rising, natural gas prices in 2010 adds to the positive story.

Unlike France, the United States did not build nearly enough nuclear power plants in the last two decades of the 20th century to accommodate its power needs, and it will spend the next two decades playing catch-up, which is why I'm reiterating my buy rating for Entergy Corp. (ETR), first recommended on May 12, 2009, at a price of $74.31.

Entergy, the second largest nuclear power generator in the U.S. (30,000 megawatts) will be a part of that mix, with its regulated utilities likely to register average earnings per share growth of 5% to 7% over the next three years. Meanwhile, the planned spin-off of its non-utility-regulated nuclear business, called Enexus, holds the promise of even stronger revenue and earnings growth. The First Call FY2009/FY2010 EPS estimates for ETR are $6.37 to $6.70.

"Peabody Energy (BTU) remains a buy in our 'gushers portfolio'." says energy sector expert Elliott Gue.

In his The Energy Strategist, he explains, "Strong demand for coal from India and China is a growth story that will play out in 2010."

Gue explains, "Peabody reported its third quarter results and share prices have reacted positively. The weakness in US coal markets remains a challenge, but Peabody has taken steps to shore up profitability in the US, cutting back planned production and locking in contracts for 2010 at fixed prices.

"Coal accounts for more than 70% of China's electricity," says Tony Sagami. In Uncommon Wisdom, he looks to an ETF poised to benefit from long-term rising coal demand.

The advisor explains, "China's coal consumption is growing, and it is building coal-powered power plants at a breakneck pace.

"Why? Because they are much cheaper to build and operate than any other power-producing option. China is power starved, and coal is the main resource used for generating electricity in the country.

"The oil-services sector remains my favorite long-term play in the energy industry," says sector specialist Elliott Gue. In The Energy Strategist, the advisor looks to industry-leader Schlumberger (NYSE: SLB).

Gue explains, "Oil services firms will benefit directly from the increasing technical complexity of oilfield development. International business is the primary driver for Schlumberger, which generated only 22% of its revenues from North America in 2008.

"The important question is, where do we sit in the cycle for international operations? In my view, the second half of 2010 will mark the beginning of a new uptrend.

There are analysts and oil gurus who argue that $30 per barrel oil is possible if the U.S./global economic recoveries stall.

$30 oil? Don't count on it, which is why I'm Reiterating my Buy rating for Anadarko Petroleum Corp. (NYSE: APC), first recommended on May 14, 2009 at a price of $43.55.

"If there was ever a stock we can hold for a few years, natural gas company Chesapeake Energy (NYSE: CHK) is it," says Ian Wyatt. Here's the latest from his Top Stock Insights.

"Chesapeake Energy is the largest independent natural gas company and most active driller of wells in the US. Its operating activities include the onshore exploration and production of natural gas.

"The Obama administration is keen on achieving energy independence for the US. Natural gas is a good option for energy, since it is inexpensive, clean and domestic. I believe the administration will continue to push natural gas as an alternative to oil, and create incentives for the industry.

"No US utility owns more of them than Exelon Corp. (NYSE: EXC), with 17 reactors," explains Roger Conrad, who chose the stock as his latest "growth spotlight" in The Utility Forecaster.

"Carbon free and, above all, paid for, existing nuclear plants are among the most prized assets in the power business.

"Some 80% of company earnings come from its unregulated generation fleet, 90% of which is nuclear. And it's by far the best-positioned US utility to ramp up nuclear output.

When Charles Dickens wrote, "Bring in the bottled lightning, a clean tumbler and a corkscrew," it's safe to say the great English novelist wasn't referring to energy technology. But in the 21st century we know that a whole lot of bottled lightning can be uncorked using a variety of sophisticated devices -- and one of the most interesting types is fuel cells.

Today we got lightning news from one of the best companies in the fuel cell space, the aptly named FuelCell Energy (NASDAQ: FCEL). Although the company reported lower product sales and revenues for fiscal Q2 of $19.3 million compared to $26.4 million in fiscal Q2 a year ago, it did say that the prior year product sales and revenues were unusually high due to timing.

"After enduring one of the worst slumps on record, we're beginning to see a rebound in all major commodities market," says Lee Lowell, adding "But one commodity stands out in particular -- natural gas."

In Xcelerated Profits Report, he explains, "This could represent the best buying opportunity in several years." Here's his review of the United States Natural Gas Fund (NYSE: UNG).

"As it so often does, it's no surprise to see the energy market leading commodities higher over the past few weeks -- specifically, crude oil and natural gas.

"Over the next five years the energy patch should offer some of the best investments around, and one standout is Schlumberger (NYSE: SLB)," says Stephen Leeb in The Complete Investor.

"Schlumberger, by a wide margin, is the best and most dominant. Its services range from well testing to pressure pumping to seismic testing, and it's No. 1 in virtually every area it occupies.

"Some of its operations, especially those that maintain the health of existing wells, are highly recession-resistant.

"As the global economy rebounds late this year or next year, demand for energy will rise again, sending prices of crude and natural gas higher," says growth and income expert Bryan Perry.

In his top-notch The Cash Machine, he explains, "With energy assets cheap by historical standards right now, I want to increase our exposure to LINN Energy LLC (NASDAQ: LINE), a best-in-class inflation hedge."

"Founded in 2003, LINN is an independent oil and gas Master Limited Partnership (MLP) that completed its initial public offering (IPO) in January 2006.

"Zero greenhouse gas emissions, 90% average availability as a power source, minimal land requirements and competitive costs: those are just a few of the advantages of geothermal power," explains Roger Conrad.

In his leading-edge New World advisory, he looks at one favorite play on the sector: Ormat Technologies (NYSE: ORA), which operates a dozen geothermal plants worldwide.

"Geothermal's chief disadvantage is geographical limitations to large-scale applications. Geothermal plants are mainly economic in areas of subsurface or volcanic activity.
