Investor Climate Change Capital Private Equity (CPE) told the Guardian that these businesses are set to move early on green technologies and that includes incorporating diode lights in their refrigerators.
However, despite the pay back that LEDs offer and the 90 per cent energy efficiency by comparison to incandescent lighting, many supermarkets cancelled orders of the technology because of the credit crunch.
Now, bulk orders have risen again from retailers, according to Alex Hanrath, associate director of the CPE.
The push for a change of has also gone beyond the supermarket.
Schools are being encouraged by the Energy Saving Trust to opt for diode bulbs in the classroom, as it could also lead to cutting costs and redistributing that funding elsewhere.
As the Times reported recently, LEDs have become part of five-star luxury hotels as they embrace sustainability.
