Top 5 Ways to Improve Energy Efficiency in Manufacturing Plants
Finding Energy Waste: How to Conduct an Energy Audit
An energy audit reveals hidden costs in your manufacturing process by analyzing how energy flows through production and support systems. On average, industrial energy audits can lead to energy savings of 15%, making them a smart investment for custom bag manufacturers.
Start by selecting an auditor experienced in manufacturing. Define the scope of the audit – whether it’s your entire facility or specific areas of production. Gather utility bills, maintenance logs, and production schedules beforehand. Assign someone from your team to guide the auditor through your facility and explain your manufacturing processes.
Begin with a review of utility bills to identify unusual patterns, and then use advanced tools like thermal imaging for a deeper analysis.
Reviewing Utility Bills and Energy Usage Patterns
Utility bills often hold the key to identifying energy waste, but they’re frequently overlooked. Analyzing 12–24 months of bills can help you uncover seasonal trends and demand spikes that may indicate inefficiencies.
Peak consumption periods are a major area for savings. Many custom bag manufacturers operate energy-heavy machinery during the most expensive times of the day. Shifting some of these operations to off-peak hours can lower costs without affecting production.
Take note of demand charges, which can make up 30-50% of your electricity bill. These charges are based on your highest 15-minute energy usage during a billing cycle. A single piece of equipment starting up inefficiently can cause a costly spike that impacts your entire month’s bill.
For a deeper understanding, consider using monitoring tools and software. Smart meters and energy management systems provide real-time data, helping you link energy use to specific production activities.
Once you’ve reviewed billing patterns, thermal imaging can help uncover hidden inefficiencies.
Using Thermal Imaging to Find Energy Loss
Thermal imaging cameras are an effective way to detect heat loss in insulation, ductwork, and equipment. For instance, up to 30% of compressed air in a typical manufacturing plant is lost to leaks, and thermal imaging can pinpoint exactly where those leaks occur.
"Money spent on proactive maintenance techniques has been proven time and again to deliver many multiples in savings." – Rob Milner, Director of Business Development for Condition Monitoring, Teledyne FLIR
Thermal imaging can reveal issues like heat loss in furnaces, hot spots in wiring, insulation gaps, gasket leaks, and product leakage. For custom bag manufacturers, this is especially useful for inspecting heating, cooling, and compressed air systems that power pneumatic equipment.
The cost of thermal imaging equipment has dropped significantly, with basic models available for around $456. Even these entry-level cameras often pay for themselves within months by identifying energy leaks.
Conduct thermal inspections when there’s a temperature difference – at least 3°F between inside and outside for general assessments, or 18°F when checking insulation. Use manual scaling with a narrow span and overlay infrared images with visual ones for better clarity.
Compressed air leaks alone can account for 2–3% of total electricity usage. In facilities using compressed air for tasks like cutting fabric or operating pneumatic presses, these leaks represent a direct hit to profits. Thermal imaging makes it easier to locate and fix these issues, ensuring repairs are effective.
Comparing Your Usage to Industry Standards
Benchmarking your energy consumption against similar facilities helps you determine whether your usage is efficient or excessive. Data from your energy analysis can be compared to industry standards to assess energy costs and carbon output.
Frameworks like ISO 50001 provide a structured way to measure energy performance. This international standard helps manufacturers establish baselines, set improvement targets, and track progress. Many custom bag manufacturers find that applying ISO 50001 principles leads to more consistent energy management.
Set measurable goals and benchmarks to monitor progress. For example, track energy use per bag produced or per square foot of fabric processed. These metrics help ensure that efficiency improvements align with production growth.
Joining industry associations or energy efficiency programs can provide access to benchmarking data tailored to textile and bag manufacturing. Some utility companies even offer free benchmarking services, comparing your facility’s energy intensity to similar operations in your area.
The depth of your energy audit will depend on your facility’s size and complexity. Government programs often provide funding to support energy audits, making it easier for smaller manufacturers to afford comprehensive assessments. These programs may also offer follow-up assistance to implement the audit’s recommendations.
A thorough energy audit lays the groundwork for smarter equipment upgrades and process refinements, driving long-term energy efficiency.
Buying Energy-Efficient Equipment
Switching to energy-efficient equipment is one of the simplest ways to lower manufacturing costs. Modern machinery often pays for itself through reduced energy expenses. Beyond slashing energy bills, these upgrades align with broader cost-control strategies. As the International Energy Agency (IEA) highlights:
"Given the predominance of motors in industrial processes, improving the energy efficiency of installed motor systems is a key way of increasing industrial technical efficiency."
To maximize the benefits, focus on upgrades that deliver the highest impact. Facilities can cut energy bills by as much as 25% through targeted equipment replacements. For custom bag manufacturers like JUNYUAN BAGS, this means significant savings on essential systems such as motors, compressors, and lighting.
When evaluating upgrades, calculate the return on investment (ROI) by dividing the annual energy savings by the initial cost. Factor in the equipment’s lifespan and any available incentives, such as federal tax breaks, to prioritize upgrades with the best payback.
Replacing Motors, Compressors, and Lighting
Motors are the backbone of bag manufacturing, powering everything from sewing machines to conveyor belts. Upgrading to premium motors can improve efficiency by 1–4%. For systems with variable loads, adding Variable Frequency Drives (VFDs) can make a big difference. Reducing motor speed by just 20% can lower energy consumption by nearly 50%. VFDs are especially effective for equipment that doesn’t always run at full capacity.
Lighting is another area where upgrades can yield quick savings. LED lighting uses only a quarter of the energy consumed by halogen bulbs and lasts 5–10 times longer. Energy Star-rated light fixtures use up to 25% less energy than traditional lighting systems and last twice as long as fluorescent options. Replacing high-bay lighting, which often operates for long hours, can significantly reduce both energy bills and maintenance costs.
Compressed air systems are another common source of inefficiency. Leaks in these systems can cost businesses $500 or more annually. Modern compressors with smart controls adjust output based on demand, ensuring the system isn’t overpowered for its actual usage.
Beyond machinery, addressing facility climate control can also lead to substantial savings.
Upgrading HVAC Systems and Insulation
Climate control represents a large chunk of energy costs, especially in facilities that need stable temperature and humidity levels for production and fabric storage. Smart thermostats and programmable controls can optimize heating and cooling by syncing with production schedules. For instance, adjusting temperatures during downtime and pre-conditioning workspaces before shifts can lower HVAC energy use without sacrificing comfort or product quality.
Switching to heat pump water heaters can reduce water heating costs by up to 60%.
Insulation upgrades often provide some of the best returns on investment. Poor insulation forces HVAC systems to work harder, driving up energy bills year-round. Use energy audits or thermal imaging to identify areas of heat loss and focus on improving those spots.
Federal tax deductions are available for energy-efficient upgrades to HVAC systems, lighting, and building insulation.
In addition to cutting costs, these improvements create a more consistent and comfortable work environment, which can boost productivity and help preserve material quality. Tracking energy use before and after upgrades ensures the savings meet expectations and builds a case for future investments in efficiency.
Improving Production Processes to Save Energy
Making adjustments to production processes can lead to significant energy savings without requiring hefty investments. These changes aim to reduce waste and streamline workflows, all while maintaining product quality and meeting production deadlines. For custom bag manufacturers, even minor tweaks to daily routines can result in noticeable cost savings.
The main goal is to pinpoint areas where energy is being wasted and apply targeted fixes. Surprisingly, optimizing processes can be just as impactful as upgrading equipment – and often pays off faster. When combined with equipment upgrades, these strategies can further reduce costs.
Using Lean Manufacturing Principles
Lean manufacturing focuses on cutting waste, which naturally lowers energy use. When applied to energy management, these principles can yield impressive results. For instance, Kaizen events – short-term, focused improvement projects – have shown quick paybacks and measurable savings in similar industries.
"The manufacturing community has an urgent need to exert control over rising energy costs. To improve financial performance particularly during turbulent times, it’s crucial for manufacturers to conserve their energy resources." – Anand Sharma, CEO, TBM Consulting Group
In bag manufacturing, lean practices can reduce energy consumption during cutting, sewing, and finishing. Tools like visual controls help standardize energy-efficient practices, while devices like occupancy sensors automatically shut off equipment when not in use.
Combining lean techniques with Total Productive Maintenance (TPM) ensures equipment runs efficiently, using less energy. A great example comes from an aluminum door and window manufacturer that reduced paint waste during changeovers from 50 gallons per day to under 10 gallons. This cut disposal costs by $280,000 annually and reduced paint and solvent waste by over 40%. Similarly, McCain Foods Ltd. saved $300,000 in energy costs at one facility by applying lean methods. General Electric also achieved substantial results, lowering greenhouse gas emissions by 250,000 metric tons and saving $70 million in energy costs between 2005 and 2007.
Energy-focused Kaizen events are particularly effective for identifying quick wins. These initiatives help teams understand energy usage in specific processes and implement immediate, impactful changes.
Running Energy-Heavy Tasks During Off-Peak Hours
Another practical way to save energy is by scheduling high-energy tasks during off-peak hours. Utility rates are often lower at night, on weekends, or during holidays when demand is reduced.
For custom bag manufacturers, activities like large-scale cutting, heat pressing, or even equipment maintenance can often be shifted to these off-peak times. By analyzing energy consumption patterns, manufacturers can identify which tasks to reschedule. Additionally, shutting down non-essential equipment during peak hours and coordinating production schedules with energy costs can amplify savings. Smart tools like programmable timers and energy management systems can automate this process, making it even easier to optimize energy use.
Reusing Waste Heat for Other Processes
Manufacturing often produces a lot of waste heat, which can be captured and reused instead of letting it go to waste. In fact, up to 80% of lost heat energy can be recovered. For bag manufacturers, heat from pressing equipment, dryers, or motors can be repurposed to preheat materials or provide on-site heating, reclaiming a significant portion of that wasted energy. Advanced energy recovery systems can achieve efficiencies as high as 94%.
For example, an ammonium sulfate fertilizer plant used a wet-scrubbing system to recover exhaust air from dryers and flash towers, generating steam and hot water. This system achieved energy recovery efficiencies between 70% and 85%, delivering both environmental and financial benefits.
Common sources of heat loss include exhaust systems, poorly sealed equipment, wall conduction, pipes, and motors. By using metering and monitoring systems, manufacturers can identify where heat is being wasted and determine the best ways to recover it. Facilities with large heating needs, like those requiring ventilation systems, can benefit greatly from waste heat recovery. Tools like heat exchangers, heat pumps, and energy recovery scrubbers are often used for this purpose. The key is finding the right applications for the recovered heat, such as process heating, industrial dryers, or even warming office spaces.
On a global scale, waste heat recovery could reduce COâ‚‚ emissions from industrial manufacturing by 1.2 gigatons annually by 2050. Typical recovery rates range from 10% to 90%, depending on the system and application. Together, these strategies not only cut energy costs but also help maintain high production standards while reducing the environmental impact.

Manufacturers have two main options for tapping into renewable energy: installing solar panels on-site or purchasing renewable electricity through utility providers. Each approach offers flexibility to match a company’s specific needs and budget.
Installing Solar Panels for On-Site Power
Solar panels allow custom bag manufacturers to produce their own clean energy, and the financial case for solar has never been more compelling. The cost of commercial solar installations has dropped significantly, making it an affordable and effective solution.
To determine the return on investment, divide the upfront cost of installation by the annual savings. Most commercial solar systems pay for themselves within 3 to 7 years if purchased outright, and they typically last 25–30 years. That means decades of reduced electricity costs after the initial investment.
Solar panels are especially practical for bag manufacturers because production often takes place during daylight hours, which aligns perfectly with peak solar generation. In fact, solar energy can cover up to 100% of daytime electricity needs for operations like cutting, sewing, and finishing.
Maintenance costs for solar systems are relatively low. Professional cleaning services range from $10 to $30 per panel, while routine inspections cost between $200 and $600 annually. Keeping panels clean is crucial, as dirt and debris can reduce efficiency by as much as 20%.
"With many of Revel’s solar customers who had looked into solar in past years reaching out to re-explore the option, they are now finding solar ROI even shorter and missing out on years of substantial savings." – Revel Energy
Before investing in solar, it’s essential to conduct an energy audit, gather multiple quotes, and assess factors like system size, panel efficiency, mounting options, and inverter technology. While the upfront costs may seem daunting, the long-term savings and energy independence make solar an attractive choice.
Buying Renewable Energy from Utility Companies
If installing solar panels isn’t feasible, manufacturers can still go green by purchasing renewable energy through utility providers. This option is ideal for facilities with roof space limitations, leasing restrictions, or insufficient capital for solar installation. By opting for renewable energy agreements, manufacturers can access clean power without the upfront costs or maintenance responsibilities.
This approach is particularly suitable for operations that require consistent, 24/7 energy or have electricity demands that exceed what rooftop solar can provide. For instance, Seiko Epson transitioned to 100% renewable electricity globally by 2023, relying on local hydroelectric, geothermal, and biomass energy sources.
"Rather than using energy generated in faraway countries, using a particular region’s abundant renewable resources brings many benefits, such as improving energy self-sufficiency and creating jobs." – Junichi Watanabe, Managing Executive Officer General Administrative Manager, Production Planning Division, Seiko Epson
Purchasing locally sourced renewable energy not only supports community job creation but also ensures predictable energy costs over the duration of the contract. Power Purchase Agreements (PPAs) provide another financing option, enabling businesses to allocate existing operating budgets toward sustainable energy solutions.
When exploring utility-based renewable energy options, manufacturers should carefully compare contract terms, pricing, and the specific energy sources offered by their local utility providers.
"Reaching 100% renewable is tough but pushing to get as close as possible, as soon as possible should be every company’s focus right now." – Christy Slay, Chief Executive Officer of The Sustainability Consortium
Both solar installations and renewable energy purchases can integrate seamlessly with other efficiency measures to stabilize operational costs. Many manufacturers find that combining both strategies – using solar panels for daytime energy needs and purchasing renewable energy for additional consumption – offers the most effective solution for achieving sustainability goals.
