Sure. Electricity right now is a product that we use on demand. One of the other folks has talked about storage, and we will get there, but we don't have a lot of storage right now so demand electricity essentially gets used when it's created. We don't have enough storage. The result is that you need to balance the demand and the supply. One of the challenges with some of the renewables, in particular wind and solar, is that the wind doesn't always blow and the sun doesn't always shine. Even when the wind does blow, it gusts, so you have different levels of supply. You need another source, usually some sort of baseload, to balance it out and create that steady draw so there is always a steady supply.
The gentleman in Alberta can probably tell you a bit about that as well because that will be one of the challenges as they move to a high level of renewables. That will be one of the things they'll need to balance out.
Just to that point, as we get more and more electrification of industry and other things, our transit, you can't have it be inconsistent. I hope that answers your question.
