Dr Kieran Mullan (Bexhill and Battle) (Con)
It is a pleasure to follow the maiden speech of the hon. Member for Bolsover (Natalie Fleet), who showed real courage in talking with emotion, pride and passion, which is not always easy in this place.
Today we are debating a number of amendments related to the strategic priorities of Great British Energy, and that will be the focus of my remarks today. I rise to ask the Government to assure the House that, given that this is not specifically mentioned in the Bill, they understand that one of the biggest challenges we face when it comes to decarbonisation is in relation to heating, and to make that a strategic priority. The UK has more than 28.5 million homes, and another 1.9 million buildings, offices, hospitals, shops, warehouses and more, the majority of which are heated by gas boilers, which also provide hot water. Nearly one fifth of all the UK’s emissions come from these buildings. The Climate Change Committee considers decarbonising heat to be one of the greatest challenges we face in getting to net zero, but that is not specified in the Bill.
Getting to net zero by 2050 will require us to pull every possible lever available. GB Energy needs to encompass the full thermodynamic meaning of the term energy, rather than focusing just on electricity. Although there is much to be said for the current plan to use air source and ground source heat pumps alongside other methods of using electric to heat buildings, attempting to convert our entire housing stock to this approach will place enormous strain on our electricity grid and supply chains.
When we consider this issue, there is one stand-out technology that will help us: geothermal energy, both shallow and deep. I am pleased to tell the House that there is cross-party consensus on this topic, and I have been able to work with a number of Members across the House, including the hon. Members for Bishop Auckland (Sam Rushworth), for Truro and Falmouth (Jayne Kirkham), for Camborne and Redruth (Perran Moon), for Rushcliffe (James Naish) and others to form the deep geothermal all-party parliamentary group. Although I have mentioned shallow geothermal, which includes technology such as coal mine water, promoted by the hon. Member for Ashfield (Lee Anderson), my remarks will focus on deep geothermal.
When I was first introduced to deep geothermal technology, my reaction was that it must be too good to be true: an environmentally friendly, dependable and cost-effective source of heat and power that can be found right under out feet—surely not. But over the past few years I have been pleasantly surprised to learn that deep geothermal is, in fact, just as good as it sounds. This technology uses the heat from naturally occurring sources of hot water deep underground to generate a large amount of usable heat and energy. In the UK, heat, rather than electricity, is the key benefit of deep geothermal, as that best matches the resources in counties such as East Sussex. This naturally occurring heat is a real resource—just as wind and sunlight are for other technologies, but unlike them it is there all year round whatever the weather.
Suella Braverman (Fareham and Waterlooville) (Con)
May I applaud my hon. Friend for really championing this innovative source of energy? May I officially log my support for Hampshire as well, because in our previous conversation we have spoken about the potential for parts of my county to exploit this energy source? Does he agree that, whether Labour says that it will not raise taxes on working people, or that GB Energy will reduce energy bills by £300, its promises are falling apart and the real way to lower energy costs is not by setting up quangos that cost the taxpayer billions of pounds, but by investing in innovative energy forms such as geothermal and other forms such as North sea oil and gas, which the previous Government did.
