The cold will bite hardest for the\u00a0<a href=\"https:\/\/commonslibrary.parliament.uk\/research-briefings\/cbp-8730\/\">13%<\/a>\u00a0of England\u2019s households that are already in fuel poverty. As the energy crisis intensifies, this is expected to rise further.<\/p>\n<p style=\"text-align: justify;\">European leaders have therefore rushed to implement measures to protect households. The UK\u2019s\u00a0<a href=\"https:\/\/www.gov.uk\/government\/publications\/energy-bills-support\/energy-bills-support-factsheet-8-september-2022\">Energy Price Guarantee<\/a>\u00a0caps the unit price of electricity and gas at 34p and 10p respectively. While this will ease some concerns over rising energy bills, many households will still be priced out of warming their home in the coming months.<\/p>\n<p style=\"text-align: justify;\">So here are four ways research indicates households can reduce their energy use in time for the winter \u2013 and save money in the process.<\/p>\n<h2 style=\"text-align: justify;\">1. Air dry laundry<\/h2>\n<p style=\"text-align: justify;\">Washing and drying clothing is responsible for around\u00a0<a href=\"https:\/\/www.gov.uk\/government\/publications\/household-electricity-survey--2\">12%<\/a>\u00a0of household electricity use in the UK.<\/p>\n<p style=\"text-align: justify;\"><a href=\"https:\/\/www.norfolknaturalliving.com\/blogs\/journal\/is-hand-washing-your-clothes-better-than-using-the-washing-machine#more-sustainable\">Hand washing<\/a>\u00a0is frequently suggested as an energy-saving alternative to machine washing.<\/p>\n<div id=\"attachment_76774\" style=\"width: 410px\" class=\"wp-caption alignleft\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-76774\" class=\"wp-image-76774\" src=\"https:\/\/www.carilec.org\/wp-content\/uploads\/2022\/11\/file-20221004-14-6s0krm-300x232.jpg\" alt=\"\" width=\"400\" height=\"310\" srcset=\"https:\/\/carilec.org\/wp-content\/uploads\/2022\/11\/file-20221004-14-6s0krm-300x232.jpg 300w, https:\/\/carilec.org\/wp-content\/uploads\/2022\/11\/file-20221004-14-6s0krm-768x594.jpg 768w, https:\/\/carilec.org\/wp-content\/uploads\/2022\/11\/file-20221004-14-6s0krm-600x464.jpg 600w, https:\/\/carilec.org\/wp-content\/uploads\/2022\/11\/file-20221004-14-6s0krm.jpg 1000w\" sizes=\"auto, (max-width: 400px) 100vw, 400px\" \/><p id=\"caption-attachment-76774\" class=\"wp-caption-text\">Hand washing laundry is often touted as an energy saving alternative to machine washing. aromaso\/Shutterstock<\/p><\/div>\n<p style=\"text-align: justify;\">Yet modern washing machines are highly efficient, typically using\u00a0<a href=\"https:\/\/doi.org\/10.3390\/su12187537\">0.5 kilowatt hours<\/a>\u00a0for a 9kg wash. This is considerably less than the\u00a0<a href=\"https:\/\/www.mdpi.com\/2071-1050\/12\/18\/7537\">0.82 kilowatt hours<\/a>\u00a0used on average by hand washing. Even inefficient washing machines tend to use less energy than hand washing as much less hot water is required.<\/p>\n<p style=\"text-align: justify;\">By instead restricting use of the tumble dryer, greater reductions in energy use can be achieved. Tumble dryers use a\u00a0<a href=\"https:\/\/www.gov.uk\/government\/publications\/household-electricity-survey--2\">lot of energy<\/a>, with a single cycle using up to 4.5 kilowatt hours. This will cost \u00a31.50 per cycle at the price cap.<\/p>\n<p style=\"text-align: justify;\">By air drying laundry instead, I calculated that the average household could save over \u00a3130 a year.<\/p>\n<h2>2. Use less hot water<\/h2>\n<p style=\"text-align: justify;\">Facing critical gas shortages, the German city of Hanover\u00a0<a href=\"https:\/\/www.theguardian.com\/world\/2022\/jul\/28\/german-cities-impose-cold-showers-and-turn-off-fountains-in-face-of-russian-gas-crisis\">turned off the hot water<\/a>\u00a0in the bathrooms of all public buildings earlier this year.<\/p>\n<p style=\"text-align: justify;\">While energy-saving measures this severe are unlikely, hot water production in the UK is a major consumer of energy, accounting for roughly\u00a0<a href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S0378778821004035?casa_token=xTAh7oY7yM8AAAAA:E-iJfrf8Z0YDsMcJRElfs2XHNswtyHpW8ims2UDwPFYv5-usqyz5ARij2m1nalnuKLB94qd1jw\">one quarter<\/a>\u00a0of household energy use. There are several ways households can reduce their hot water use.<\/p>\n<p style=\"text-align: justify;\">One way is reducing the time spent in the shower. A high-pressure shower lasting nine minutes uses around\u00a0<a href=\"https:\/\/www.waterwise.org.uk\/wp-content\/uploads\/2018\/02\/United-Utilities_Water-and-Energy-Efficient-Showers_Project-Report.pdf\">4.3 kilowatt hours<\/a>\u00a0of gas. At the price cap, this will cost households 44p per shower. By reducing the time spent showering to six minutes, households can save 15p on heating water for each shower.<\/p>\n<p style=\"text-align: justify;\">If you have a hot water tank, making sure it is well insulated can also deliver cost savings. This will keep water warmer for longer and reduce heating costs.<\/p>\n<p style=\"text-align: justify;\">Another approach is to install a low-flow shower head. This restricts the flow of water while maintaining the feel of a high-pressure shower. At lower flow rates, a shower will consume less hot water. For households that average two nine-minute showers a day, this could save over \u00a3100 per year.<\/p>\n<p style=\"text-align: justify;\">However, a low-flow shower head will only work well in areas where the water pressure is already sufficiently high. Reducing the flow of an already low-pressure shower would transform the shower into a dribble.<\/p>\n<h2 style=\"text-align: justify;\">3. Make better use of heating<\/h2>\n<p style=\"text-align: justify;\">As the energy crisis intensifies, it is important to make sure heating is not wasted unnecessarily.\u00a0<a href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S0306261917315829?casa_token=lm5ZgEAZhMUAAAAA:iqGWb6BegjNur8LBAkMpQpQJbLia8FWyhVA_R0evSz82rDLFdv1c_JEQjftGRyXSn6HG13dj1w#b0015\">Research<\/a>\u00a0indicates that energy use could be slashed by up to 30% by reducing heating when occupants are asleep or away.<\/p>\n<p style=\"text-align: justify;\">This can be done by manually dialling down the thermostat or by turning the heating off altogether. For those who habitually forget to lower the heating, a smart thermostat could prove a useful investment. These can be controlled remotely via your mobile, or automatically through presence sensors and allow heating to be lowered when the home is unoccupied.<\/p>\n<div id=\"attachment_76776\" style=\"width: 410px\" class=\"wp-caption alignleft\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-76776\" class=\"wp-image-76776\" src=\"https:\/\/www.carilec.org\/wp-content\/uploads\/2022\/11\/Capturecarere-300x201.png\" alt=\"\" width=\"400\" height=\"268\" srcset=\"https:\/\/carilec.org\/wp-content\/uploads\/2022\/11\/Capturecarere-300x201.png 300w, https:\/\/carilec.org\/wp-content\/uploads\/2022\/11\/Capturecarere-1024x686.png 1024w, https:\/\/carilec.org\/wp-content\/uploads\/2022\/11\/Capturecarere-768x514.png 768w, https:\/\/carilec.org\/wp-content\/uploads\/2022\/11\/Capturecarere-600x402.png 600w, https:\/\/carilec.org\/wp-content\/uploads\/2022\/11\/Capturecarere.png 1217w\" sizes=\"auto, (max-width: 400px) 100vw, 400px\" \/><p id=\"caption-attachment-76776\" class=\"wp-caption-text\">Homes with heating controls use much less energy than homes without.

However, it is important that the doors between rooms remain closed to prevent energy being wasted.<\/p>\n<h2>4. Maximise insulation<\/h2>\n<p>Although we can make better use of heating, Britain\u2019s homes are hugely energy inefficient. Its housing stock is one of the\u00a0<a href=\"https:\/\/www.theccc.org.uk\/wp-content\/uploads\/2017\/01\/Annex-2-Heat-in-UK-Buildings-Today-Committee-on-Climate-Change-October-2016.pdf\">least insulated<\/a>\u00a0in Europe.<\/p>\n<p>Maximising your insulation is one way to reduce your energy use.

I calculated that this could save the average UK home over \u00a350 per year in heating costs.<\/p>\n<p>But window shutters do not always represent an immediate energy-saving strategy. Shutter installation can be costly and if installed on a building\u2019s exterior may require planning permission.<\/p>\n<p>Closing blinds or curtains at night and during cold spells instead represents a cheaper way of retaining heat. Research indicates that blinds can reduce the amount of heat lost through windows by\u00a0<a href=\"https:\/\/doi.org\/10.1016\/j.enbuild.2004.11.008\">up to 38%<\/a>.<\/p>\n<p>Changes in habits and small investments can substantially reduce energy consumption.

While the Energy Price Guarantee will provide temporary relief to many, investment in energy efficiency measures such as insulation must be prioritised to reduce our energy burden longer term.<\/p>\n<p><strong>SOURCE: <img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-76778\" src=\"https:\/\/www.carilec.org\/wp-content\/uploads\/2022\/11\/Conversation-300x47.png\" alt=\"\" width=\"172\" height=\"27\" srcset=\"https:\/\/carilec.org\/wp-content\/uploads\/2022\/11\/Conversation-300x47.png 300w, https:\/\/carilec.org\/wp-content\/uploads\/2022\/11\/Conversation.png 474w\" sizes=\"auto, (max-width: 172px) 100vw, 172px\" \/><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A particularly cold September has given us a glimpse of the winter to come.
