As energy costs rise and environmental pressures increase, sustainability actions are becoming essential for industries that use a lot of energy.
Here’s a guide to practical steps heavy energy users can take toward a more sustainable future.
#1 Energy Benchmarking
You can’t improve what you don’t measure. Understanding your current energy use is the first step to making changes. By conducting an energy audit or benchmarking exercise, you can spot areas of waste and identify easy improvements. Small changes can make a big difference.
#2 Quick Sustainability Wins
Sustainability doesn’t always require big investments. Small steps can help you reduce your carbon footprint and save money, setting the stage for bigger sustainability investments later. Start with “early-win” measures that are cost-effective but offer immediate results, like:
- Switch to LED lights as old bulbs burn out.
- Improve insulation to reduce heating costs.
- Service energy-hungry equipment like boilers and fridges to keep them running efficiently.
#3 Involve Your Employees
It’s not just about equipment; people matter too. Raising awareness among your team can lead to big energy savings. Simple actions like turning off lights, unplugging unused equipment, or adjusting thermostats add up over time. Get your team involved with energy-saving challenges, and use posters or newsletters to keep them motivated.
#4 Shift to Renewable Energy
One major step toward sustainability is switching to renewable energy sources. Though it may require some upfront investment, the long-term benefits are huge. With the rise of renewable energy infrastructure, it’s becoming easier and cheaper for large energy consumers to make the switch. In Ireland, wind energy is a strong option, but solar, hydropower, and geothermal energy can further diversify your energy sources and boost resilience.
#5 Optimise Heating Systems
Heating often accounts for a large chunk of energy use. But, small investments can help you save money while improving comfort for employees. Here’s how to make your heating system more efficient:
- Set thermostats to maintain temperatures between 19-22°C for comfort and energy savings.
- Insulate your building to prevent heat loss, especially around windows and doors.
- Use recirculating fans to redistribute warm air more efficiently.
#6 Waste Heat Recovery
Many industries generate waste heat during their processes. Instead of letting it go unused, consider investing in waste heat recovery systems. These systems can capture heat and turn it into usable energy, improving efficiency and reducing your carbon footprint. In some cases, these systems can boost energy efficiency by up to 70%, paying for themselves quickly.
#7 Embrace the Circular Economy
A sustainable business doesn’t just “take, make, and dispose.” It adopts a circular economy model, where materials are reduced, reused, and recycled. This minimises waste and increases efficiency, benefiting both the environment and your bottom line. Consider reusing materials in production or recycling waste products as part of your sustainability strategy.
#8 Manage Waste Effectively
Effective waste management is key to sustainability. Minimising waste can significantly reduce your environmental impact. Start by tracking waste across your operations and identifying areas for improvement. Strategies include:
- Sorting waste into recyclables, compostable materials, and refuse.
- Reducing single-use plastics.
- Printing less and using double-sided paper when possible.
#9 Invest in Battery Storage
With more businesses adopting renewable energy, battery storage systems are becoming increasingly important. These systems store energy during off-peak hours and use it during peak times, helping you cut energy costs and improve efficiency. Battery storage also reduces your reliance on grid power, making it a smart long-term investment for sustainability.
#10 Thermal Energy Storage
Another energy-saving option is thermal energy storage, like ice storage or hydronic tanks. These systems store excess energy as thermal energy and use it later when needed, reducing the need for additional energy inputs. They also provide resilience during peak energy demand or power outages, ensuring smooth operations.
#11 Build a Microgrid
For large energy consumers, microgrids offer an independent power solution. A microgrid is a localised energy system that can operate independently of the main utility grid, providing more control over energy use and reducing costs. It can help optimise energy production and consumption, which is especially useful during power outages or disruptions.
#12 Provide EV Charging Stations
As electric vehicles (EVs) become more popular, offering EV charging stations on-site is an easy way to improve sustainability. These stations support employees who drive electric cars and align your business with the trend toward electrification. Some companies are even exploring vehicle-to-grid (V2G) technology, which allows EVs to return energy to the grid and further boost sustainability.
#13 Extend Sustainability to Your Supply Chain
Your sustainability efforts shouldn’t stop at your company’s doors. Look for suppliers that also prioritise energy efficiency, ethical sourcing, and low-carbon practices. Encourage them to reduce their environmental footprint and explore green logistics options like electric delivery fleets and optimised transportation routes to reduce emissions.
#14 Take Advantage of Resources & Incentives
Financial support can make the transition to sustainability easier. Grants and resources are available to help you improve energy efficiency and adopt renewable energy systems. In Ireland, check out these options:
- Grants and Incentives: Financial support for improving energy efficiency and installing renewable energy systems.
- Enterprise Ireland: Offers sustainability advice and funding opportunities for businesses.
- Climate Toolkit for Business: A free survey providing personalised tips for increasing sustainability.
