Climate change isn't going to be free. A report by Point Carbon, an independent consulting company that tracks global carbon and energy markets, estimates that U.S. climate legislation could push the price at the pump 13 cents a gallon higher. The increase would result from the cost to oil companies for carbon permits, which they can pass along to consumers.

This is a much rosier view than that of the oil industry, however, which believes a U.S. cap-and-trade system would thrash demand for gasoline and lead to the shuttering of many refineries.

Since the stock market bottomed in March of this year, it has been firing on all cylinders -- except for those in the auto industry who manufacture the most cylinders of course. This year has not been kind to them.

For months, many have been surprised at the rapid rise, given the level of unemployment. During this same period, Wall Streeters have been dancing up and down, looking forward to more bonuses.

As the number of unemployed has climbed and the period of same has lengthened, many have wondered how business could be improving during a time when the consumer (those still left) has transformed from spender to saver.

While I'm chasing value, General Electric (NYSE: GE) is chasing revenue from water projects. It may not amount to much now, but GE is betting it will be huge some day and it has been working towards this goal for many years.

Although GE had estimated 2009 revenue of $2.5 billion from the water business, that is only a meager 1.6% of the $156 billion in worldwide sales generated by its major business divisions that the world's largest maker of jet engines and electricity-producing turbines is expected to generate this year.

As the name suggests, Green Mountain Coffee Roasters (NASDAQ: GMCR) is based in the pastoral state of Vermont. The company offers about 180 varieties of coffee, cocoa, and tea, which it sells to wholesale customers including supermarkets, convenience stores, resorts, and office delivery services.

Some of its biggest customers are ExxonMobil's convenience stores and McDonald's restaurants. In September, Green Mountain acquired Tully's Coffee, which has been chipping away at Starbucks' dominance in the Pacific Northwest.

This morning Exxon Mobil (NYSE: XOM) reported its second quarter numbers, and the oil giant posted its lowest profit in nearly six years.

Going into this morning's earnings announcement analysts were expecting to see the company show earnings of $1.02 per share. Exxon did not even come close, with a reported 84 cents per share excluding one time items.

Suncor Energy (NYSE: SU) is a vertically-integrated oil company located in Canada. Unlike its vertically-integrated brethren in the United States, this Canadian stock is up more than 40% this year. By comparison, Exxon Mobil (NYSE: XOM) is down 13%, and ConocoPhillips (NYSE: COP) is down more than 20%.

The reason for the big difference in performance is the weakness in the dollar. That makes Canadian-based Suncor more valuable to investors.

"Stocks, by just about every long-term valuation measure, are undervalued," says John Reese, who continues to recommend putting money to work in undervalued stocks.

In his Validea newsletter, he selects "undervalued" issues by using screens based on the investment strategies of leading investors such as Peter Lynch, Ben Graham and Warren Buffett. Here's a a look at four current buys in the oil sector.

Reese explains, "If you think you can predict investors' emotional states, or how an unprecedented economic crisis will play out, then go ahead and wait for the bottom. I suffer no such delusions, however.

"Rather than playing the risky game of bottom-calling -- which more often than not leads to investors missing the big initial push of a new bull run -- I'll continue to put money into undervalued stocks.

"What can get this market going again?" asks Chuck Carlson. In The DRIP Investor he says, "It's helpful to understand what stocks within the Dow need to do well for the index to do well."

"Not surprisingly, IBM (NYSE: IBM), the highest-priced stock in the Dow, carries the greatest weighting at more than 9% of the index. Obviously, with such a heavy weighting in the index, IBM will need to be a decent performer for the Dow to do well going forward.

"And when you total up the exposure of IBM with the other tech stocks in the Dow - Microsoft (NASDAQ: MSFT), Intel (NASDAQ: INTC), and Hewlett-Packard (NYSE: HPQ) - the total tech weighting in the Dow is 16%. Thus, tech stocks matter to the Dow, so it is diffcult to see the Dow sustaining a move upward without a nice rebound in the tech sector.

I read a very interesting cover story article in BusinessWeek about Exxon Mobil (NYSE: XOM). I am usually skeptical of cover story articles, but they are onto something with this story (ok, that is maybe because I agree with them).

As I've said in the past, Exxon is a classic religion stock, meaning investors own it because it has done so well in the past and because it is the best-managed oil company. Exxon is not analyzed; it is just owned -- bought or inherited and never sold. Well, neither reason is enough to just blindly own a stock which is what happens when one becomes a religion stock.

ExxonMobil Corp. (NYSE: XOM) is scheduled to discuss fourth-quarter and year-end 2008 results tomorrow, January 30, in a conference call at 11:00 AM ET hosted by David Rosenthal, vice president -- investor relations. You can catch the live audio webcast of the call on the company's website.

For the quarter that saw a settlement with the EPA and DOJ, analysts polled by Thomson Reuters expect Exxon to report a profit of $1.45 per share, compared to $2.13 per share in the same period of the previous year. Revenue for the quarter is expected to total $69.1 billion, down 40.7% from a year ago. Exxon's earnings fell short of estimates in three of the past five quarters, by as much as 9.7%.
