Right. I'm just curious about that, because several yards and tonnages of concrete go into every wind turbine tower. The amount of steel that goes into them is massive. We know that concrete is one of the largest GHG emitters in the world. I was just curious to know whether you guys bothered to put that into your analysis. I guess not.
My last question is for Natural Resources.
There was a two-year delay in developing the just transition policy because of COVID, yet we're not seeing the timelines moved by two years for all of these towns, for all of these communities and for these sectors that are going to be obliterated by the just transition, especially in the coal industry. I'm just wondering how you can justify a two-year delay without actually giving a two-year reprieve to these communities.
