To make it happen, the government needs to make electricity much cheaper, and make the savings meaningful for consumers or companies who would gladly install, for example, a heat pump for free if a customer could pay them back over the lifetime of the product through bill savings and still come out on top compared to a gas boiler.
It also models making electricity cheaper by shifting the "policy costs" (essentially green levies and part of the warm homes levy) off the electricity part of bills where they currently sit and onto the gas part, making EVs and heat pumps immediately more affordable and gas boilers less so.
By 2038 to 2042, the majority of homes will need to have ditched their gas boiler for a heat pump, switched to an electric car, and probably be eating a bit less meat (cleverly, the committee expert invoked kebabs as the semi-official yardstick here: meat eating must fall from the equivalent of eight kebabs a week to six by 2050.
Then there's the rising tide of anti-net zero sentiment from the right of British and international politics, whose message is: that saving the planet will ruin consumers, hobble the economy and is iniquitous given the UK has done so much already and we're just a small contributor to global warming.
Unlike similar domestic technology roll-outs that happened just as fast - the internet, fridges, mobile phones - heat pumps and EVs won't bring any immediate benefits into the home unless they are cheaper or better.
