[en] This paper discussed the use of integrated resource strategic planning (IRSP) as a means of reducing greenhouse gas (GHG) emissions. Integrated resource planning (IRP) is used to plan for supply- and demand-side resources in the electric power industry. However, its effectiveness has been diminished by the restructuring of the power sector throughout the world. Selection and investment in generating facilities are now determined by unregulated market forces. By contrast, IRSP provides a low carbon electricity model for national resource planning. The tool can be used to determine key barriers and measures for energy efficiency and emissions reductions. Demand side management (DSM) practices for reducing primary energy demand were also discussed. A case study of IRSP in California was used to demonstrate the method's ability to promote energy efficiency. 16 refs., 5 tabs.
