I thank the hon. Gentleman for that Intervention. Like him, I represent a rural Constituency, where concern about rising petrol and diesel costs is bearing down heavily on families. For people in Ceredigion private cars continue to account for the overwhelming Majority of commutes. Indeed, in Wales as a whole about 80% of people have to commute by car. Sadly, for people in Wales, and particularly in rural areas, there is no short-term alternative to using private cars, so those rising fuel costs are having a devastating impact. Of course the long-term solution would be greater investment in public transport infrastructure, but, as an MP representing a rural area, I know how devastating cuts to bus services have been in the last decade so, sadly, for the time being using the bus instead of a private car is not a viable option.

The crisis has also demonstrated the need for longer-term action, such as action to boost productivity, and green solutions to help address the energy supply emergency and in so doing to alleviate stagnating living wages. We can ease the crisis in the long term by reducing energy demand. We have discussed that often in this place and debates have also been held in the Senedd in Cardiff. If we reduce fuel and energy demand, we also reduce fuel Bills.

A good place to start is with the simple measure of improving household heating efficiency. At the autumn Budget I called on the Chancellor to make a £3.6 billion investment over 10 years, in conjunction with the Welsh Government and the private sector, to improve home insulation in Wales. It is well-documented that the quality of Welsh housing stock is poor by both British and European standards, and its energy efficiency is, sadly, a sight to behold. Introducing measures to improve the heat and energy efficiency of our homes would not only boost employment in areas that are desperately in need of levelling up through the retrofitting schemes, but would also address Fuel Poverty. A report by the Future Generations Commissioner for Wales has suggested that with such a package of investment over 10 years we would be able to end fuel poverty in Wales, producing average annual savings of £418.
