How to cut energy usage?

 Why do some businesses effortlessly slash energy bills while others struggle to make a dent? It's not just about turning off lights or setting the air con higher. The real difference lies in strategy, automation, and understanding how human behaviour intersects with tech.

If you're running a large business—or advising one—energy savings isn’t just about the environment anymore. It’s a hard-nosed financial lever. And with electricity prices surging and sustainability expectations tightening, the cost of inaction is rarely zero.

Here’s your smart, strategic guide to cutting energy usage—backed by behavioural science, Aussie market insight, and a whole lot of common sense.

What’s the fastest way to cut energy use in a business?

Short answer? Automate first, then optimise.

Manual efforts—like asking staff to switch things off—rely on habit, attention and motivation. And as anyone who’s managed people knows, those aren’t always reliable.

Instead, automate where possible:

  • Smart lighting systems that adjust to occupancy and daylight

  • IoT-enabled HVAC controls that respond to usage patterns

  • Automated scheduling of high-energy equipment to off-peak hours

These systems not only reduce waste but also anchor behaviour—staff adapt to the automated defaults, which is a classic nudge in behavioural economics. Defaults are powerful; people tend to accept them because they reduce friction.

A case study from a Brisbane logistics company found that switching to occupancy sensors cut warehouse lighting costs by 42% overnight—without a single staff email sent.

Where are most businesses wasting energy without realising?

Surprisingly, it's not just outdated equipment or poor insulation. It's invisible inefficiencies:

  • Idle equipment running after hours

  • Overcooling of commercial spaces (especially in Aussie winters)

  • Simultaneous heating and cooling—often due to poor thermostat placement

  • Data centres and servers left running at max capacity 24/7

There’s a behavioural bias here: the status quo effect. Once systems are in place, businesses rarely revisit them. It “feels easier” to leave things as they are—even if it’s costing thousands annually.

What’s the smartest way to influence staff energy behaviour?

You can’t automate everything. Some behaviours still depend on people—like shutting fridge doors in hospitality, or turning off displays at closing time.

So what works?

  • Social Proof: Show how energy champions in your business are making a difference. “85% of teams on Level 3 switched off equipment last week” creates a powerful sense of unity and peer pressure.

  • Public dashboards: Visual energy displays in break rooms or intranet portals help make energy use visible—and trigger commitment bias.

  • Micro-commitments: Get staff to agree to simple pledges (“I’ll turn off my station before leaving”)—then reinforce them weekly.

It’s not about guilt—it’s about creating a culture of consistency.

How do automated systems save energy for large businesses?

Let’s get tactical. Here’s where automation truly delivers scale:

  • Building Management Systems (BMS): Control lighting, HVAC, and even blinds automatically based on schedules, seasons, and occupancy.

  • Smart meters and analytics platforms: Track consumption in real time, identify anomalies, and automate responses (e.g., switching off systems during peak tariffs).

  • AI-powered demand forecasting: Predict and reduce demand spikes, which cost more due to demand charges.

These systems pay off in both dollars and effort. Once set up, they require less daily oversight, which reduces the “attention tax” on your team.

We’ve seen major retailers in Australia implement smart load controls that shaved 6–9% off their monthly bills—with no visible impact on store comfort or service levels.

How do energy savings affect business reputation?

In 2025, brand perception is power.

Customers, investors, and even talent want to see real sustainability, not just token gestures. Cutting energy usage isn’t just a financial move—it’s a brand positioning play.

Businesses that publish their savings and emission reductions often see:

  • Stronger customer loyalty (especially Gen Z and millennial buyers)

  • More favourable procurement scores in B2B tenders

  • Better staff retention—because people want to work somewhere that "walks the talk"

Don’t underestimate Liking—Cialdini’s principle that people say “yes” to those they admire and relate to. Sustainability makes brands more likeable—when done authentically.

Is it worth upgrading equipment for energy efficiency?

Short answer: If it’s old, probably yes.

Energy-efficient gear costs more upfront, but modern systems pay themselves off fast. For example:

  • LED lighting retrofits return investment in under 2 years

  • High-efficiency HVAC units save 20–40% over legacy systems

  • Smart refrigeration systems in food retail can drop energy use by 30%

But here’s the kicker: many large businesses still anchor their upgrade decisions on outdated ROI models. This is the anchoring bias in action—basing choices on old data points instead of current costs and savings.

Newer energy-efficient systems often come with automation baked in, amplifying the savings.

Are solar panels still worth it in 2025?

Yes—but with caveats.

Solar remains a solid long-term strategy, especially with battery storage prices continuing to fall. However, the payback period depends heavily on:

  • Site usage patterns

  • Roof orientation and shading

  • Available feed-in tariffs (which vary across states)

For large businesses, solar is often more than just a savings tactic—it’s a PR and stakeholder tool, too. Transparent reporting of solar generation boosts credibility in ESG reporting and investor conversations.

And let’s face it: a rooftop full of panels just looks like a business that’s switched on.

What’s a quick win for businesses not ready to invest big?

If you’re not ready to dive into major CapEx upgrades, try these:

  • Run an energy audit: Even a basic one can reveal low-hanging fruit.

  • Set HVAC boundaries: Lock thermostats to rational temperature bands.

  • Adjust equipment schedules: Align usage with business hours.

  • Use plug load controllers: Auto-kill power to devices after set hours.

  • Encourage daylight use: Rearrange office layouts to maximise natural light.

These small steps, when layered, often compound into noticeable reductions.

How do you future-proof energy savings?

Good question—and it’s less about tech, more about mindset.

  1. Measure everything: What gets measured gets managed.

  2. Bake energy into KPIs: Make it part of performance reviews, operations plans, and supplier criteria.

  3. Stay curious: Tech is evolving fast—from virtual power plants to AI-driven optimisation.

  4. Choose systems that integrate: Future upgrades should plug into your current stack easily.

  5. Plan for regulation: Australian climate policy is tightening. Staying ahead isn’t just smart—it’s risk management.

The businesses that win tomorrow are building energy strategy into their core operations today.

FAQ

How often should we audit energy use?
At least annually. But if you're running a multi-site operation, quarterly reviews give you faster feedback.

Is automation only for big corporates?
Not anymore. Prices have dropped significantly. Even mid-sized warehouses or retail chains can implement smart solutions affordably.

What’s the best temp to set the office air con?
Experts recommend around 24–25°C in summer, 20–21°C in winter. Every degree you adjust can save up to 10% on cooling or heating costs.

And if you're wondering where to begin, look at where others are heading. Many large Australian businesses are choosing to automate energy savings as a practical first move—and it's paying off fast.

For broader context, the Australian Energy Regulator offers a solid breakdown of proven energy-saving tips tailored to business and residential users alike.

Final Thought
Energy savings aren’t a side project—they’re a business strategy. And like any good strategy, it rewards those who act early, think smart, and commit fully. Because in the race to net zero, half-measures rarely win.
