It takes a good bit of energy to make, but it is just one part of the concrete.
The labor involved in all the handling of the concrete and its various components is the biggest cost.
I have read of some supply problems for cement powder in some areas but no one I know has been affected by this.
Construction is still busy.
Some are predicting a slow down and I have seen recessions before.
When that happens (watch rising rates) commodity prices can come down really, really fast but so far the trend is still up.
Thanks for coming back on that. My own interest is copper and aluminum, which consume tremendous amounts of electricity, which comes from the power grid, which is fueled by coal and natural gas. I am thinking we might have to do some vertical integration and get off the power grid just to continue to operate. I don't believe the anti-monopolists or greenies will be pleased to see the coal being delivered.
