Programs Requiring Direct Adjustment to Energy Demand

In some cases, changes in demand or investment levels are already estimated from research, meaning the goal of the policy file is to simply get these specific values into the model to see how they impact emissions or the economy. ENERGY 2100 contains several variables to exogenously shift demand or investments. 


The current versions of these files typically read in a series of values representing the estimated energy and investment changes from a program, then split out the values into the covered sectors and technologies by using demands from a base or reference case forecast. In most cases the input values are assumed to be the overall reduction from the program, so the policy file will generally apply the marginal difference in the year-to-year value. In addition, often values are additionally adjusted in the forecast to account for a ‘rebound’ effect of the model attempting to re-build missing stock values. 


Due to the factors above exogenous reduction policy tend to be longer and more difficult to understand at first glance compared to most other demand policy files. Work is planned design a simpler approach for applying exogenous changes.
