The UK could reduce its total energy consumption by 1% by having the five top British supermarkets were to open doors on their refrigerators, according to campaigners.
Aldi has announced plans to install doors on its fridges in all its newly opened UK stores, thereby saving the equivalent of 2,000 tonnes of carbon per year.
Others say that they’ll try to make fridges that are open more efficient.
However, it was the Environmental Investigation Agency said supermarkets could reduce their power costs by an average of 33% by installing doors.
The 100 Aldi new stores will save 20 tons of carbon annually by installing doors on refrigerators the German chain announced, adding it will reduce the energy use of stores by 20%..
Glamorgan Environmentalist and Glamorgan Cricketer Joe Cooke say all supermarkets that operate across Wales should follow in the footsteps of Joe Cooke.
“It’s such a simple change,” Cooke declared. “It could save so much energy, that’s going to be so important for us as we try to decarbonize and make the changes to become a greener country.”
Cooke stated that only Co-op and Aldi were committed to putting refrigerator doors in all of their brand new and recently renovated stores.
Mary Dunn, Aldi UK’s chief executive officer responsible for corporate, stated: “Introducing fridge doors is another step on that journey to reduce our energy consumption and we hope that customers enjoy the new, more sustainable shopping experience.”
However, Tesco, Sainsbury’s, Morrisons, Waitrose, and M&S all stated that they will utilize “air wall” technologies that push cold air toward the back of display cases to help save energy.
Lidl has said it uses curtains in its stores when they are closed. Asda has announced that it will be testing doors for chilled display areas in 2022.
Ulla Lindberg a consumer and refrigeration researcher at Swedish refrigerator maker Haglund Industry, said fridges with doors can outperform even the most efficient open-cabinet technology.
Ms. Lindberg’s study found that food consumers were not shut off by the doors and many felt that food was fresher.
Supermarkets equipped with refrigerator doors resulted in less food waste and helped supermarkets to lower their heating bills during winter, since they require less warmth in the chill sections of their stores, Lindberg stated.
“Half of the energy in a supermarket is from the refrigeration so that means that you cut a lot [with doors],” she explained.
“You can also improve the situation for the consumer and the food as well.”
The Welsh Assembly’s petitions committee looked at the possibility of banning refrigerators that are open in supermarkets in 2019 but the members decided that the Welsh government was not in possession of the power to take action.
The UK government has decided against an outright ban on the use of fridges and freezers that are open in retail stores in 2019, and also said the government was taking measures to boost the efficiency of energy use.
In an announcement in a statement, in a statement, the Department for Business, Energy and Industrial Strategy stated that the department was “looking at various ways to encourage greater energy efficiency in commercial refrigeration”.
“We urge retailers to increase their use of energy-efficient technology wherever possible,” it said.
