Yes. In terms of efficiency, our history in Canada is a storied one in hydro power. We operate at over 90% efficiency, meaning that when turning the water power into electricity, when it goes through the turbine, that conversion happens at an over-90% rate in general throughout our facilities in Canada.
There are always opportunities to up that percentage, but comparing hydro power with other sources of electricity generation, we'll see other ones coming in around the 60% or 40% range at their upper limits.
When you look at raw efficiency, as you mentioned, hydro power is a clear leader.
