The Sustainable Shopper: What Can Greengrocers, Cornershops & Supermarkets Do To Reduce Their Energy Use?



Jump To

In the hustle and bustle of our daily lives, we often overlook the environmental impact of our routine activities. One such activity is our regular visit to the local greengrocer, cornershop, or supermarket. These establishments, while essential to our daily lives, are significant contributors to high energy consumption and, consequently, climate change. By understanding the approach that local shops and larger corporations take to sustainable practices, consumers can make more informed choices about where they’re spending their money. 

The Energy Consumption Conundrum

Supermarkets, greengrocers, and cornershops rely heavily on energy-intensive systems such as refrigeration, lighting, and heating. These systems are crucial for preserving food and providing a comfortable shopping environment. 

However, they consume vast amounts of electricity and gas, often sourced from non-renewable resources like natural gas and coal. This high energy consumption not only strains our national electrical grid but also contributes to greenhouse gas emissions and air pollution.

So, what can these establishments do to reduce their energy use and environmental impact? Here are a handful of actionable strategies you should be looking out for.

Embrace Energy-Efficient Technologies

The first step towards reducing energy consumption is to upgrade to energy-efficient technologies. For instance, replacing traditional lighting systems with LED technology can significantly reduce energy usage. LEDs not only consume less energy but also have a longer lifespan, reducing the need for frequent replacements.

Similarly, installing occupancy sensors and smart lighting control systems can help manage energy use more effectively. These systems adjust the intensity and duration of lighting based on customer activity, ensuring no unnecessary energy consumption.

Switch To Renewable Energy Sources

Renewable energy sources such as solar power, wind power, biomass, and hydropower offer a sustainable alternative to fossil fuels. By switching to these sources, establishments can significantly reduce their carbon footprint and greenhouse gas emissions. Plus, renewable energy can also lead to cost savings in the long run, benefiting the business’s bottom line.

A potential solution is to compare supermarket energy providers who offer renewable energy sources such as biomass, solar power or wind power. 

Invest In Energy Management Systems

Energy management systems allow businesses to monitor and regulate their energy consumption in real-time. These systems can adapt lighting and HVAC settings based on occupancy levels and time of day, reducing wasted energy. By identifying and resolving energy inefficiencies, these systems can result in substantial cost savings.

Combat Food Waste

Food waste is another significant contributor to energy consumption within the food supply chain. By implementing efficient inventory management techniques, establishments can prevent food spoilage and reduce food waste. Donating excess food to charities, educating shoppers on proper food storage, and maintaining refrigeration equipment can all help in this regard.

Raise Consumer Awareness

Businesses can play a crucial role in promoting sustainable practices among consumers. Encouraging the use of reusable bags, promoting locally sourced products, and providing educational resources can all help foster a more environmentally conscious mindset among shoppers.

Retrofitting Existing Equipment

Retrofitting existing equipment with more energy-efficient models is another effective way for supermarkets to reduce energy consumption. For instance, old refrigeration units can be retrofitted with advanced insulation and energy-saving compressors. This not only reduces energy usage but also extends the lifespan of the equipment, leading to cost savings in the long run.

Regular Maintenance & Energy Audits

Regular maintenance of equipment can prevent energy wastage due to inefficiencies. For example, ensuring that refrigeration units are well-insulated and free from leaks can significantly reduce energy consumption. Additionally, conducting regular energy audits can help identify areas of energy wastage and provide insights into how energy consumption can be further reduced.

Implement Green Building Practices

Green building practices, such as using energy-efficient building materials and incorporating natural light into the store design, can significantly reduce energy consumption. For instance, using skylights or large windows can reduce the need for artificial lighting during the day. Similarly, using insulation materials in the building design can reduce the need for heating and cooling, leading to significant energy savings.

The Path To Sustainability

Reducing energy use in greengrocers, cornershops, and supermarkets is not just about protecting the environment. It’s also about improving operational efficiency and financial sustainability. By embracing energy-efficient technologies, switching to renewable energy, and promoting sustainable practices, these establishments can make a significant contribution to the fight against climate change.

So, How Can Consumers Check How Sustainable & Energy Efficient Their Local Shops Are?

When it comes to identifying sustainable and energy-efficient supermarkets in the UK, there are several resources and certifications to consider. Here are some ways to find out:

  • Carbon Trust Certification: The Carbon Trust is an independent, expert partner of leading organisations around the world, helping them contribute to and benefit from a more sustainable future. They provide certifications to businesses that are reducing their carbon emissions. You can check their website for a list of certified organisations: Carbon Trust
  • Energy Saving Trust: This is a UK-based organisation dedicated to promoting energy efficiency, energy conservation, and the sustainable use of energy. They provide endorsements for energy-efficient businesses. Check their website for more information: Energy Saving Trust
  • BREEAM Certification: BREEAM is the world’s leading sustainability assessment method for master planning projects, infrastructure and buildings. They provide certifications for businesses that are sustainable in their operations. You can check their website for a list of certified organisations: BREEAM
  • Greenpeace’s Plastic Scorecard: Greenpeace UK ranks supermarkets based on their use of single-use plastics. While this doesn’t directly relate to energy efficiency, it’s a good indicator of a supermarket’s overall commitment to sustainability. Check their latest scorecard here: Greenpeace Plastic Scorecard
  • Company Websites: Many supermarkets publish their sustainability initiatives on their websites. For example, Sainsbury’s has a dedicated section on their website where they detail their sustainability efforts: Sainsbury’s Sustainability
  • Ethical Consumer: Ethical Consumer provides a detailed breakdown of the ethical and environmental record of various supermarkets. They rate each supermarket in several categories, including environmental reporting, palm oil policy, and climate change. Check their supermarket guide here: Ethical Consumer Supermarket Guide

Remember, while these resources can provide a good starting point, it’s also important to do your own research and make informed decisions based on a variety of factors.

The Bottom Line

Remember, every small step towards sustainability counts. So, the next time you visit your local supermarket, don’t forget to bring your reusable bag and choose locally sourced products. Together, we can make a difference.
