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.

In his top-notch The DRIP Investor he says, "The seven stocks featured here have each been paying a dividend for over 100 years, have raised their dividend annually for at least the last quarter century and offer direct-purchase plans.

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.

Beijing-based Sinopec's net income surged to 22 billion yuan ($3.22 billion) in the three months that ended June 30, according to estimates by Bloomberg News. That easily topped the analysts' consensus estimate of 15.8 billion yuan.
