Electrification versus efficiency: Where should industrial facilities focus first?

According to the U.S. Department of Energy (DOE), the industrial sector accounts for about one-third of U.S. energy-related carbon dioxide emissions, making industrial energy strategy a high-impact area.

As industrial facilities look for ways to meet sustainability goals, optimize operations and invest in energy efficiency, moving certain equipment and processes to electricity can potentially be a smart long-term strategy.

But for many facilities, electrification may not be the best first move.

Before changing how energy is supplied for a facility, it often makes sense to look at how energy is being used right now. In many industrial environments, efficiency improvements can deliver faster returns, lower risk and clearer operational benefits. They can also make future electrification decisions easier, more affordable and more effective.

The question is not whether electrification or efficiency matters more. The better question is: what should come first?

Electrification has an important role to play.

Electrification can be a powerful tool in the right applications. For some facilities, replacing fuel-powered equipment with electric alternatives can help support sustainability goals, reduce on-site emissions and improve long-term energy flexibility.

It can be especially worth exploring when equipment is already nearing the end of its life, when electric alternatives are proven and available, or when leadership is building a long-term plan around emissions reduction and modernization.

Examples of electrification opportunities include electric forklifts, certain heat pump applications, electric process equipment where technically feasible, or infrastructure planning that prepares the site for future electric loads.

But electrification is rarely a simple swap. It can require capital investment, engineering review, electrical capacity planning and a close look at how changes may affect demand, production schedules and operating costs. That does not mean industrial facilities should avoid electrification. It means they should approach it with a clear plan.

Efficiency often delivers the fastest practical wins.

Efficiency is usually less flashy than electrification, but it can be one of the most practical places to start.

Instead of replacing entire systems or changing fuel sources, efficiency focuses on reducing waste and improving the performance of what is already in place. For many facilities, that can mean upgrading lighting, improving compressed air systems, optimizing HVAC, adding variable speed drives, improving controls or using commissioning to fine-tune systems that use more energy than they should.

These projects often have a more straightforward business case. They can reduce energy use, lower maintenance costs, improve visibility or comfort, and help equipment operate more reliably.

The results are not theoretical. DOE’s Better Plants Program encourages manufacturers and water utilities to set long-term goals to achieve significant energy and water intensity improvements over a 10-year period across all their U.S. operations. 

Oak Ridge National Laboratory reports that DOE Better Plants partners have achieved $11.8 billion in cumulative cost savings, 2.4 quadrillion BTUs in energy savings and 147 million metric tons of CO₂ avoided.  

Efficiency upgrades can also be easier to phase. A facility may not be ready for a major electrification project across the plant, but it may be ready to replace outdated lighting in a warehouse, repair compressed air leaks, improve motor controls or evaluate high-use systems.

That matters because industrial teams are rarely making energy decisions in a vacuum. They are balancing production goals, capital budgets, maintenance needs, safety priorities and leadership expectations. Investing in efficiency gives industrial facilities a practical way to make progress without waiting for the perfect long-term plan.

Why efficiency often comes first.

For many industrial facilities, improving efficiency before electrifying creates a stronger foundation. Here’s why.

Energy efficiency lowers the load before adding new demand.

Electrification can increase the electric load. If a facility adds new electrical equipment without first addressing waste, it may be building on an inefficient baseline.

According to The American Council for an Energy-Efficient Economy (ACEEE), a nonprofit research organization, planning for added electrical load is a key best practice for electrification, which reinforces why facilities should understand and reduce waste before adding new demand.

Efficiency improvements help reduce unnecessary energy use first. That can make future electrification easier to plan and, in some cases, reduce the size or cost of the infrastructure needed to support it.

Use less first, then decide what to add.

Investing in efficiency can improve your business case.

Many efficiency projects can deliver measurable savings faster than larger infrastructure changes. Lighting upgrades, compressed air improvements and system optimization can often show a clearer connection between investment and return.

A 2025 International Energy Agency (IEA) survey of 1,000 industrial facilities found that energy efficiency investments are paying off. About 70% of respondents reported ROI above 10% on efficiency upgrades made in the past five years.

Those savings can also support future projects. When a facility reduces waste and lowers operating costs, it may create more room in the budget for larger energy investments down the road.

It’s not an either/or choice between efficiency and electrification. Efficiency can help pave the way toward electrification.

Efficiency can reveal what your facility actually needs.

An energy strategy should be based on real facility conditions, not assumptions.

Efficiency often starts with data, assessments or system reviews. That process can uncover where energy is being wasted, which systems are underperforming and which upgrades are likely to have the greatest impact.

Benchmarking can also help teams avoid guesswork. ENERGY STAR’s plant performance tools use actual plant data to show how efficiently a facility operates compared with similar plants.

These insights are valuable whether the next step is an LED lighting upgrade, a compressed air project, a controls improvement or a future electrification study.

Efficiency gives teams a clearer map before they make bigger moves.

The smartest facilities are sequencing both.

Industrial facilities do not have to choose efficiency or electrification forever. In many cases, the strongest strategy is to sequence both. In fact, the DOE’s own industrial roadmap does not frame the path forward as efficiency or electrification. It encourages both as key pathways, alongside low-carbon fuels and carbon capture.

A practical roadmap might look like this:

1. Assess your current performance.
Start by understanding where energy is being used, where waste may be happening and which systems are creating the highest cost or maintenance burden.

2. Prioritize high-impact efficiency projects.
Look for improvements that can reduce energy use, lower maintenance needs, or improve operations, backed by a clear business case.

3. Optimize how systems run.
Controls, scheduling, monitoring and energy management practices can help ensure savings last and systems continue to perform as intended.

4. Evaluate electrification where it makes sense.
Once you reduce waste and understand plant performance better, you can make electrification decisions with more confidence.

A better first question.

Instead of asking, “Should we electrify?” industrial teams may be better served by asking, “What should we improve first?”

For some facilities, the answer may be electrification. For many others, the answer may be efficiency, optimization or a closer look at systems that have not been evaluated in years.

The best path depends on the facility, the equipment, the goals and the budget. But in most cases, reducing waste first makes every next move stronger.

Electrification may be part of the future. Efficiency helps make that future easier to reach.
