Negawatts: Twelve Transitions, Eight Improvements, and One Distraction

The author outlines twelve fundamental transitions in electricity efficiency, moving from fragmented equipment upgrades to integrated, whole-system optimization. He argues that 'negawatts' (saved electricity) are often cheaper than new generation and that market failures currently penalize efficiency. The paper proposes eight improvements to make efficiency programs more cost-effective and critiques the concept of 'retail wheeling' as a distraction from the more significant shift toward wholesale competition and decentralized generation via fuel cells and superflywheels.

• Integrated packages of efficiency measures are significantly more cost-effective than fragmented, component-by-component upgrades because they account for interactions that can eliminate the need for costly mechanical equipment.
• Energy efficiency should be approached by optimizing the application first and the equipment second; for instance, reducing cooling loads through better glazings and passive cooling should precede upgrading the refrigerative system.
• Energy-saving improvements can yield labor-productivity gains of 6–16% by improving visual, thermal, or acoustic comfort, making the economic value of these 'negawatts' an order of magnitude higher than their energy value alone.
• The author contends that 'retail wheeling' is not a 'deregulatory tsunami' but a distraction; he suggests 'virtual retail wheeling' as a superior alternative that maintains the benefits of competition without the jurisdictional and legal complexities.
• The emergence of decentralized generation technologies, such as proton-exchange-membrane (PEM) fuel cells and carbon-fiber superflywheels, may eventually render central thermal power stations obsolete.
• PEM fuel cells in 'hypercars' could provide a massive amount of generating capacity if plugged into the grid, potentially representing ~3 TW of capacity, which is four times the total capacity of all current grid-connected generators in the U.S.
• Utility efficiency programs in California demonstrated high cost-effectiveness between 1991 and 1994, with average program costs falling from 2.8 to 1.9 current ¢/kWh.
