One approach to cogeneration (electricity and heat) for a community is to design the facility to satisfy heating needs and to import or export electricity as needed. This approach is based on the philosophy that it is much easier to market excess electricity (or purchase it as needed) than to sell excess heat. Consider a typical natural gas-fired cogeneration facility that produces electricity at an efficiency of $40 \%$ and has $50 \%$ of the waste energy available for heating purposes. Discuss the validity of this approach for a northern community (near Anchorage, AK) compared to a southern community (near New Orleans, LA). Provide quantitative comparisons to support your evaluation. Are there other approaches to cogeneration that would be more reasonable for one, or both, of these locations?
