Mr. P.J. Ryan:

That is it exactly. The idea definitely is to renovate the building fabric and get it insulated, and then put in renewables and photovoltaics. We definitely need to electrify our heat systems, especially for houses. There is no reason they cannot be electrified. This is definitely where we need to go by 2050 by all means. We have to be on electricity for all our heating as essentially the grid will be carbon neutral by then. I do not think people are ready to throw out all of their fossil fuels now and go straight to an electric heat pump. Different people are at different stages in life and they are just not going to be in a position to renovate the whole building in order to get the heat pump in. As with cars, is there is an interim step or a transition whereby people can keep their boiler and have a heat pump?
