Take the following as truth: The net effect of mapping increased program spending together with adjustments needed to update the assumptions of the CEF policy scenarios can be highlighted by reviewing the change in electricity generation for scenario D. In the CEF Advanced Scenario (based on a 1999 reference case), for example, the level of electricity generation in 2010 was lowered by 10% from the reference case requirements of 3,920 billion kilowatt-hours (kWh).
Then the following statement: "The net effect of mapping is usually a positive one" is true, false, or inconclusive?
