APPENDIX 8-D. LIFE-CYCLE COST ANALYSIS USING ALTERNATIVE 

ECONOMIC GROWTH SCENARIOS FOR FURNACES

8-D.1 INTRODUCTION

This appendix presents LCC results using energy price forecasts from alternative 

economic growth scenarios. The scenarios are based on the High Economic Growth case and the

Low Economic Growth case from the May 2010 release of the AEO2010.

1 To estimate energy 

prices after 2035 in the high and low scenarios, DOE used the growth rate between 2020 and 

2035.

The forecasts in these cases are shown in Appendix 10-B. Energy prices are higher in the 

High Economic Growth case and lower in the Low Economic Growth case. The energy price 

forecasts affect the energy savings at different efficiency levels.
