If we're being honest, there's just a lot of uncertainty, period, right now in terms of where some of the pieces are. There are the financial tools that are still being deployed. We're working through the clean electricity regulation process, and there is uncertainty going forward about what carbon pricing will look like.
Uncertainty, as Peter said, is bad for decision-making. It slows us down in terms of the investments that we have to make to get ourselves to 2050, so I think that's where our focus will be.
