"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.

It goes without saying, that the oil/oil services sectors are preferred here. Look for oil to remain a major fuel for propulsion for at least three more decades, even with alternative energy source development. And with the aforementioned in mind, Occidental Petroleum (NYSE: OXY) is worth a review.

Occidental Petroleum engages in oil/gas exploration and also makes basic chemicals, plastics, and petrochemicals. The company has proved reserves of 3 billion barrels of oil equivalent in three regions: U.S./North America, Middle East, and Latin America.

"The global oil and gas majors have been brutally wounded since energy prices peaked last July," observes resources expert Eric Roseman.

In his Commodity Trend Alert, he explains, "We believe it's safe to start accumulating these companies again. We're buying one of the largest and best-managed natural gas companies in the world – Encana (NYSE: ECA)."

The advisor notes, "Based in Calgary, Alberta, Encana is Canada's largest natural gas distribution company based on stock market capitalization and natural gas production.

"ECA produces approximately 4.4 billion cubic feet of gas equivalent per day. More than 80% is natural gas - the cleanest burning of all fossil fuels.

"We see smooth seas ahead for deepsea driller Oceaneering International (NYSE: OII)," says Richard Moroney.

The editor of the blue chip advisory, Dow Theory Forecasts, explains, "Most of the world's untapped oil reserves lie under the ocean floor, and oil producers are spending an increasing portion of their capital budgets on deepwater drilling."

"While oil prices don't directly affect Oceaneering International's profits and cash flows, they do move the stock. Oil prices fell by two-thirds in the second half of 2008, pushing Oceaneering shares under $20 for the first time since July 2005.

"Many experts believe that oil prices are at unsustainably low prices now, and they expect a sharp rise in the commodity price as supply and demand come back into line again," says turnaround expert George Putnam.

In The Turnaround Letter, he suggests, "If oil does begin to rise again, the oilfield service stocks could rebound sharply." Here, he takes a look at large cap plays on a rebound within the oilfield services sector.

"We all know that oil prices have fallen dramatically from their highs in the summer of 2008. But different types of oil-related stocks have reacted quite differently to the price change in the underlying commodity.

"For example, while oil itself has dropped nearly 70% from its 12-month high, the stock of the largest integrated oil company, Exxon-Mobil (NYSE: XOM), is down only 26%, less than the stock market as a whole.

TheStreet.com's Jim Cramer says that Dominion Resources saw a lot of the green movement coming and moved aggressively.

What do you do with a company that raises its dividend twice in two years by 11%, that has superior growth characteristics in its sector, enlightened management and a plan for executives to buy stock regularly?

Well, in this market, that's an easy question to answer: You sell it. That's what's been going on with Dominion Resources (NYSE: D) (Cramer's Take), the Richmond, Va.-based utility that yields more than 6%, but is bumping along its 52-week low like every other stock I follow.
