Energy Efficiency

May I welcome you to your post, Mr Deputy Speaker, and the Ministers to theirs? I also congratulate all hon. Members who have made very eloquent and interesting maiden speeches today, particularly my hon. Friend the Member for North Tyneside (Mrs Glindon), who raised pertinent issues about workers in the civil service. I am conscious of the fact that some Back Benchers on both sides of the House are still waiting to speak and that we are yet to hear the wind-ups, and as I am particularly interested in what the Minister is going to say, I shall keep my comments brief. I am pleased to have the opportunity to participate in a debate on an issue as important as "Progress and prospects in energy efficiency". I am glad that we have heard a bit more detail today about the green deal—the detail provided in the Budget and the coalition agreement was sketchy. What we have heard about the green deal today has raised as many questions as answers. The Minister talked about energy-efficient products, including loft insulation and plugs. I wish to focus briefly on another very simple element of energy-efficient products, which was not discussed. The Energy Saving Trust estimates that 23% of the heat energy lost from a house escapes through inefficient windows, so it is vital that efficient windows are included in measures under the green deal. I know from dialogue that I have had with the Glass and Glazing Federation—the trade association that represents companies, including those in my constituency, who make, supply or fit glass and glass-related products—that the current economic downturn has been particularly damaging to the glass and window industry, and that at the current rate of installations the dates in the carbon emissions reduction target will not be met. My right hon. Friend the Member for Lewisham, Deptford (Joan Ruddock) highlighted the fact that glazing can cost about £10,000. That will not be met by the green deal at the limit stated by the Minister—that is if the green deal is to extend to energy-efficient glazing at all. Can he clarify whether the support for insulation that he outlined through the green deal and other projects will include that provided by energy-efficient windows? Will he consider a windows scrappage scheme? Estimates made by the Glass and Glazing Federation's energy savings calculator, which have been supported by the Energy Saving Trust, demonstrate that such a scheme could provide even greater benefits to energy conservation than those obtained from the excellent boiler scrappage scheme introduced under the Labour Government. A number of references have been made to the number 10 during this debate. A number of Members on both sides of the House have signed the 10:10 pledge to reduce our emissions by 10% over the course of this year. We learnt today from the Committee on Climate Change that the UK's carbon emissions have been reduced by 10% in the past year. If energy-efficient windows were installed in all properties nationally, our emissions would reduce by a further 10%, saving nearly 4 million tonnes of carbon and decreasing our national domestic energy expenditure by 10%. I urge the Minister to consider energy-efficient windows in his plans.
