Low-cost strategies for coping with CO2 emission limits.

Argues that there are more options for reducing carbon dioxide (CO2) emissions through energy demand reduction and energy supply shifts than those considered by Alan Manne and Richard Richels in the initial run for their model. Information on Manne and Richels' model; View that a broader energy program is needed; Opportunities for energy demand reduction; Alternative low CO2-emitting electricity supply technologies.
