Demand shaping and shifting

We have learned that one of the principles of sustainable software engineering is demand shifting and demand shaping. Haven't we seen this before? Yes—we learned how to perform demand shaping from a cost-perspective point of view in Chapter 4, Planning for Cost Savings – Right Sizing, under the Sample logic for cost control section; so, let's see if this can also be applied to carbon efficiency.
