Rajendra Pachauri, U.N. climate scientist, has good news and bad news. I'll give you the latter first: eat less meat. Doing so will help slow global warming. The good news, also related to climate change, is that Pachauri, chairman of the Intergovernmental Panel on Climate Change for the United Nations, investing in green technologies now is a smart move. So, by following Pachauri's advice, you cut down on your meat but reward yourself with a decent investment return.

If you take his advice as a whole (pretending you don't know you can do one part without the other), it's like getting paid to eat your veggies. Everyone who's been five years old at some point knows that being given green to eat green is ample motivation. The fun part, here, is that you're financing it by investing in green. It all matches!

"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.

"The US natural gas storage cycle is fairly straightforward: More gas is consumed in winter than in summer because natural gas is a key source of heat," explains Elliott Gue.

In his industry-leading The Energy Strategist, the energy sector specialist makes a bullish case for natural gas as well as contract driller Nabor's Industries (NYSE: NBR).

"The year started off with gas storage levels falling in line with the average. In late February or early March that all changed: Storage levels jumped and eventually broke to a new five-year high.

In his Validea newsletter, editor John Reese picks stocks based on the long-standing strategies of "legendary" investors, including investment stars as Warren Buffett, Peter Lynch, and others known for long-term records of success.

Here, the advisor takes a look at Chevron (NYSE: CVX), based on the investment strategy of leading growth and value investor James O'Shaughnessy.

"O'Shaughnessy's approach, know as the Cornerstone Value Strategy, looks for large, well known companies whose market cap is greater than $1 billion. These companies exhibit solid and stable earnings. CVX's market cap passes this test.

"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.

"Our focus this summer remains on building positions in the bombed-out natural gas market; there's no other commodity this depressed, this unwanted and trading at such distressed levels," says resource expert Eric Roseman.

In his industry-leading, The Commodity Trend Alert, he explains, "Indeed, the bombed-out natural gas sector is screaming 'buy'." Here, he looks at TransCanada Corp. (NYSE: TRP).

"The way prices have been heading over the last several months you'd think the world doesn't use this clean-burning fossil fuel anymore.

"Natural gas prices remain 70% off their 52-week high and more than 75% below their all-time highs almost four years ago when Hurricane Katrina smashed the Gulf of Mexico.

"Despite coming close to bankruptcy in 2002, Williams Co. (NYSE: WMB) has some of the premier assets in each of its business segments: exploration & production, mid-stream and pipelines," says turnaround expert George Putnam.

In his The Turnaround Letter, he explains, "The company now has the financial strength not only to survive the current downturn but to grow and prosper."

"Begun in 1908 as a pipeline construction company, Williams is now a major, integrated natural gas company; it produces, gathers, processes and transports natural gas throughout the United States.

"National Oilwell Varco (NYSE: NOV), a buy in our 'Wildcatters portfolio,' will see an outsized benefit from improving conditions in the global oil market," says Elliott Gue in The Energy Strategist.

"Rig technology is the crown jewel of National Oilwell's business; the unit builds key equipment used on land and offshore drilling rigs.

"The unit is currently benefiting from the boom in deepwater drilling activity -- one of the only drilling markets that continue to see growth.

"Equipment used on deepwater drilling rigs is far more complex and expensive than that used on land or shallow-water rigs. As a result, selling equipment into the deepwater market carries far higher profit margins for National.

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.

"I have four Hurricane Season stock picks -- two bullish, two bearish -- to play this summer's potentially wild weather," says Sean Broderick in his Uncommon Wisdom advisory.

"Last year's stormy weather spawned 16 named storms, which was higher than the long-term average of about 10 tropical storms and six hurricanes per year in a typical Atlantic hurricane season.

"The major hurricane forecasters have now made their predictions, and it's for a 'moderate' hurricane season. That's good news for America's oil and gas industry.

"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.
