Okay.
My other question is also kind of open-ended. It's about what kind of skills training needs to occur when the electricity distribution system changes. If you have a smart grid, if you have distributed generation, presumably some retraining needs to be done for people who work with the local distribution companies, for example.
I also understand that there will be a big gap in the electrical power industry as people retire over the next 10 years, that there will be a lack—or a potential lack, because of course we could do something about it now—of workers.
Would you like to make some comments about that?
