Mr. Dermot Byrne:

We can certainly come back to the Senator. She asked about ambition and if money was no object, we would still have a supply chain issue at a time when we are building more houses. We are working with partners to try to develop and build that supply chain and we will see that happening over the next number of years. That will get us to where we need and want to get to in the later years of the decade.

We have to scale up public buildings. We have a national heat study under way at the moment which will help to inform new policies, actions and how we do all of this.

The Senator touched on retrofitting and the embodied energy piece. It is not something that I have looked at in detail but perhaps I could come back to the Senator on that matter.

Storage is one of a number of technologies that are increasingly being used to manage the variability of wind. Our biggest issues relate more to the long-term storage, the Turlough Hills of this world, to manage the intermittency of it over a period of time. Storage is certainly a part of the solution, as is interconnection. We have already got two interconnectors to the island of Ireland and hope to have two more by the middle of the decade - the Celtic interconnector and the GridLink interconnector. All of that will help.

I will come back to the Senator on the rest of the issues she raised because of the time limits. I am aware of the issue she raised about the energy charter. It is not something I am following in detail because I do not think it applies in Ireland, or I hope it does not. We will see what happens in that regard.
