Production levels of unconventional oil and gas, nuclear, 

 solar, and solids (coal and biomass) are modeled as "backstop 

 technologies." That is, a base level of production is assumed to 

 be generated over time if real prices remain constant. Shorter- 

 term supply schedules are then superimposed on these long-term 

 trends to reflect the increase or decrease in production due to
