First up, I'd say these aren't savings that we're planning. This was a study that was undertaken for a federal-provincial-territorial work group. It's based on whether certain actions are taken across the economy. It's based on the technological opportunities and instruments that are available to governments. These are the potential savings that could result. They are spread over that period of time, so some of them might be front-end loaded, as you describe. Some might require major changes in equipment, which doesn't happen very frequently. That's why going to 2025 is useful, because we can pick up some of those that will be economic that you can't pick up in the nearer term.
To summarize, there are a large number of activities, including actions taken by governments, that could put these savings in place. The study helps us identify those potential savings in terms of the sectors and the uses of electricity and other forms of energy, and what kinds of policy instruments governments could consider if they want to see those kinds of savings.
