An estimated $900 billion of direct infrastructure investment will be required by electric utilities over the next 15 years, and $750 million already is in place. Nukes, renewables, low-carbon technologies, combined-cycle gas turbines—all have faced cost challenges. The magnitude of the numbers requires a multi-pronged approach.

Seven CEOs—from Exelon, Great Plains Energy, National Grid, NRG Energy, Duke Energy, FPL Group, Great River Energy—explain how global warming is affecting their customers, shareholders, and employees.

Demand response reduces overall energy usage, but the magnitude of the reduction depends on whether the technologies are developed and deployed with efficiency in mind.

Utilities need to begin planning for U.S.-wide emissions restrictions that will be more effective than state efforts. Such restrictions are no longer a matter of “if,” but “when.”

Micro maverick Bill Althouse sees a grand conspiracy to blot out customer-owned generation.

Distributed generation is out of the box. It's time for regulators to wake up. The paradigm has already shifted."

That's Bill Althouse talking, president of Althouse Inc. of Albuquerque, N.M., a seat-of-the pants business (he says he's near bankruptcy) that helps homeowners and businesses install on-site generation. I met him via email as I researched why, on Jan.

U.S., rest of the world ponder CO2 emissions, with utilities caught in the middle.

Four months from now, in Kyoto, Japan, international policy negotiators will decide how quickly to curtail carbon dioxide emissions and allay the world's fears of melting ice caps and rising temperatures.

The amendments to the United Nations Framework Convention on Climate Change, or FCCC, are likely to be founded more on world and domestic politics than on science. Industry climatologists, after all, insist the atmosphere is not warming as fast as others predict, and could be, in fact, cooling.
