Keeping energy costs under control is a top priority for any manufacturing business. Beyond just cutting expenses, improving energy efficiency also helps reduce environmental impact. The good news? There are plenty of ways to save energy without compromising productivity. Here are ten practical steps to help lower your energy bills while making your operations more sustainable.
-
Start with an Energy Audit
Before making changes, you need to understand where your energy is going. An energy audit will highlight inefficiencies and pinpoint areas where you can cut back. Whether it’s outdated equipment, unnecessary usage, or poor insulation, an audit gives you a clear action plan to improve efficiency and reduce waste.
-
Upgrade to Energy-Efficient Equipment and Lighting
Switching to energy-efficient machinery and LED lighting can make a huge difference. While it may seem like a costly investment at first, newer manufacturing equipment uses less power and runs more efficiently. LED lighting alone can cut energy use by up to 75% compared to traditional bulbs and lasts much longer, saving both energy and maintenance costs.
-
Automate with Smart Energy Management
Smart systems can take the guesswork out of energy savings. Motion sensors can turn off lights in empty rooms, and automated thermostats can adjust heating and cooling based on real-time needs. These small changes add up quickly, reducing energy waste and keeping costs down without requiring extra effort from employees.
-
Take Advantage of Off-Peak Energy Rates
Many energy providers offer lower rates during off-peak hours. By shifting high-energy activities—like running heavy manufacturing machinery or charging equipment—to these times, you can take advantage of reduced tariffs and save money on your energy bills.
-
Routinely Maintain your Equipment
Regular maintenance keeps machinery running at peak efficiency and prevents energy-wasting breakdowns. Schedule routine servicing, replace worn parts promptly, and ensure proper lubrication to reduce unnecessary energy consumption. Even small inefficiencies can add up to big costs over time.
-
Improve Heating and Insulation
Heating and cooling can be major energy drains in manufacturing. Proper insulation in walls, pipes, and ceilings helps maintain temperatures without overworking heating or air conditioning systems. Recapturing heat from production lines and optimising boiler efficiency can also lead to significant savings.
-
Optimise Compressed Air Systems
Compressed air systems are often overlooked but can be massive energy users. Fixing leaks, reducing operating pressure, and turning compressors off when not in use can all help lower energy waste. Even a small reduction in pressure can lead to noticeable savings.
-
Switch to Renewable Energy
Generating your own energy with solar panels or wind turbines can dramatically cut electricity costs in the long run. If installing renewable energy sources isn’t feasible, switching to a green energy supplier that provides 100% renewable electricity or carbon-neutral gas is a great alternative.
-
Involve Your Team
Energy efficiency isn’t just about equipment—it’s about behaviour too. Encourage employees to turn off unused machinery, optimise heating and lighting, and follow best practices for energy conservation. Simple actions, like shutting down computers at the end of the day, can make a big impact when multiplied across an entire team.
-
Use Variable Speed Drives for Motors
Motors are one of the biggest energy consumers in manufacturing. Installing variable speed drives (VSDs) lets motors adjust their speed based on demand, significantly reducing energy use. A 20% speed reduction can cut energy consumption by up to 50%, making this a smart investment for long-term savings.
Making energy efficiency a priority doesn’t just help cut costs—it makes your business more sustainable and competitive. Even small changes can lead to big results over time. Whether it’s investing in new technology, adopting smarter working habits, or switching to renewable energy, each step you take brings you closer to a more efficient and cost-effective operation.
