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.

For the first half of 2010, almost two thirds of money managers are bullish, according to Barron's. In fact, 54% are bullish, and 5% are "very bullish." Responses suggest that the Dow Jones Industrial Average is expected to gain another 5% by the end of the year.

According to Barron's, "Today's bullish investors see the major stock indexes making steady progress through next June, amid signs the U.S. economy is on the mend after a searing recession."

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!

General Electric Company (NYSE GE) plans to ramp up its solar power division. GE already has a foot in the market, but up to this point it has produced only $200 million in sales.

GE made a minor acquisition in the solar field with the purchase of Astropower, and it acquired a stake in PrimeStar Solar. Now GE is taking a long-term view of the energy market and sees it as a multi-billion dollar industry. Jeff Immelt, GE's chief executive officer, told the Financial Times that energy was "clearly one of the big industrial businesses filled with what I would call seismic change, whether it's clean energy or scarcity of resources."

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.

Oil took a beating tyesterday, as investors sold off the precious crude in the wake of a weak consumer confidence report that renewed pessimism towards economic recovery.

The University of Michigan reported that its consumer confidence index dipped to 63.2, down from 66 in July. This is the second straight month that the index has moved lower, after a four month streak of gains. In June the index was up at 70.8, which was the highest since back in February 2008.

Duke Energy (NYSE: DUK) has to wonder if Al Gore knows exactly what he is talking about when it comes to global warming.

This morning, the power company announced that its second-quarter profit fell to 21 cents per share from 28 cents per share a year ago. Excluding items, the company would have earned 26 cents per share, which is a penny better than the consensus estimate. Revenue for the quarter fell to $2.91 billion from $3.22 billion a year ago and far short of the consensus estimate. The blame for the year-over-year profit decline falls squarely on the shoulders of mark-to-market losses on economic hedges.

Some trends are obvious enough and visible to all investors. Others are more subtle but are just as potent, and these often slip "under the radar."

Case in point: Water and energy use is trending lower, and a good example is the City of New York. Water consumption has been dropping on per capita (or per person) basis, basically, for 25 years.

A 79% return is both astounding and not enough. T. Boone Pickens has seen his energy funds push that much higher this year, but it comes on the heels of 2008, in which his firm, BP Capital, lost more than 90% of its value – plunging from assets under management of more than $4 billion to $500 million. The Energy Equity fund lost 64% of its value, with the Energy Fund off 98%.

The 54% decline in oil prices from last summer – from a record high of $147 – not only pushed Pickens' investments lower but prompted him to exit positions and, in October, lift restrictions on withdrawals by his clients.
