"Canada's tar sands are in fact the largest proven oil reserves outside of Saudi Arabia. Tar sands are already 65 percent of overall Alberta oil output and are expected to hit 88 percent by the end of the decade," says Roger Conrad.

The editor of the specialty newsletter, Canadian Edge, reviews a trio of oil sands producers -- Penn West Energy Trust (PWE), Suncor (SU) and Cenovus Energy (CVE) -- that he states "truly worth investing in."

The advisor continues, "Starting with the most conservative, Penn West Energy has inked a joint venture with giant sovereign wealth fund China Investment Corp (CIC) to deploy the latter's capital to develop its oil sands properties.

"In your father's day, investing in energy was easy; fifty years ago, our fathers simply bought stock in one or two of the Seven Sisters oil companies, sat back, and let the money come in," says Martin Hutchinson.

The contributing editor to The Money Map Report explains, "The 'Sisters' owned pretty well all of the world's oil reserves. They had the world's best oil extraction and refining technology. They marketed the product to motorists, power stations, chemical companies, and all other users of the black gold. They made consistent profits, grew steadily as oil consumption increased, and paid good dividend."

"Canadian energy giants Suncor Energy (NYSE: SU) and PetroCanada (NYSE: PCZ) announced their intention to merge; Suncor, a holding in our 'Wildcatters Portfolio' will be the surviving entity," says Elliott Gue.

In his The Energy Strategist, he explains, "The combined firm will be the fifth-largest energy company in North America and the largest in Canada." Here, he explains why the new stock remains a buy.

"The combined firm will have more financial flexibility than Suncor did on its own. Debt ratios will be healthier, and the combined firm will also be able to redirect certain planned capital expenditures to higher return potential projects.

"It may have been a rough and tumble year for natural gas, but the market is coming back with a vengeance," says Kevin Kerr in his Marketwatch Global Resources newsletter.

The natural gas market has had "an extremely volatile 12 months of trading," he recalls. Both the Amaranth hedge fund trading debacle and the lack of hurricanes over the past season drove the prices to extreme lows.

Now, he says, "All that may be changing as wholesale prices soar." Indeed, natural gas has rallied to a two-month high, coincident with the cold froze in the northern U.S.

According to Kerr, the "Perma-bears" in the natural gas market are discounting the cold weather, stating that it is hitting late in the season. They also are leery of gas inventories that are 21% higher than the average for the past five years.
