How to Use Less Electricity in Your Business: 5 Practical Tips
Shock your friends with this post.
Key Takeaways
- Cooling and lighting are the usual starting points: in a Darwin business, air conditioning and lights tend to run the longest hours.
- Idle equipment still draws power: switching off at the wall costs nothing and adds up across a whole workplace.
- Efficient equipment pays back over time: check the Energy Rating label before you buy.
- An audit shows where the money goes: it gives you a written plan instead of guesswork.
How to Use Less Electricity in Your Business: 5 Practical Tips
Power is one of those costs that quietly climbs, especially in the Top End where air conditioners run for most of the year. When we are asked how to use less electricity in your business, the answer is that a few simple changes go a long way.
Below are the five tips we give Darwin and Palmerston business owners, from free habits to upgrades that pay for themselves over time. Start with the table, then read the detail on each tip.
| Tip | Effort | Cost |
|---|---|---|
| 1. Switch off unused equipment | Low | Free |
| 2. Use natural light well | Low | Free |
| 3. Upgrade to LED lighting | Medium | Low to medium |
| 4. Buy energy-efficient equipment | Medium | Medium |
| 5. Book an energy audit | Low | Paid |
Where Business Power Usually Goes
Every business is different, so there is no single answer. We find it helps to list your biggest loads first, then work out which ones you can change. The table shows common places to look.
| Area | Why it uses power | What to check |
|---|---|---|
| Air conditioning | Runs for long hours in Darwin | Servicing, filters, thermostat settings |
| Lighting | Often left on all day | Old globes, unused rooms, timers |
| Refrigeration | Runs around the clock | Door seals, age, location |
| Office equipment | Idle draw adds up | Power boards, shutdown routine |
| Motors and pumps | Often run at full speed | Variable speed drives |
Once you know the biggest loads, the five tips below are much easier to prioritise.
1. Switch Off Unused Equipment
We often point out that a computer in sleep mode is still using power. So are monitors, printers, microwaves and coffee machines left plugged in overnight. Each one is small, but a whole office running around the clock adds up.
Make it a closing routine that the whole team follows:
- Shut down computers and monitors rather than leaving them asleep
- Use switched power boards so a whole desk turns off at once
- Switch off printers, kitchen appliances and chargers at the wall
- Ask the last person out to check the office and storeroom
Put one person in charge of the routine or set up a simple roster, because habits only stick when someone owns them.
2. Make the Most of Natural Light
Daylight is free, so we suggest using it where possible. Open blinds in areas with good light and keep lights off in rooms that do not need them. Skylights and windows can cut the hours your lights run.
In Darwin, direct sun can also heat a room and make the air conditioner work harder. Blinds on sun-facing windows help you keep the light without the heat. It is also worth checking for areas that are brighter than they need to be, because over-lit rooms waste power.
3. Upgrade to LED Lighting
LED globes and tubes use a fraction of the power of old halogen and incandescent lights, and they last much longer. For a business that has lights on all day, the savings add up quickly, and you spend less time and money replacing globes.
Places to start:
- Shopfronts, offices and workshops where lights run all day
- Outdoor and security lighting that stays on overnight
- Warehouse and storage areas with older fittings
- Any light you replace more than once a year
- Display and feature lighting that is on for opening hours
If you are unsure which globe suits a fitting, ask us during a visit and we will match the right LED to the job.
4. Choose Energy-Efficient Equipment
When equipment needs replacing, we tell clients running cost matters as much as purchase price. In Australia, look for the Energy Rating label, which shows how much power an appliance uses. More stars generally means lower running costs.
Air conditioning and cooling are the big ones in Darwin, so keep them well maintained. Our guide to the signs your split system needs servicing shows what to watch for. If you run pumps or motors, a variable speed drive can cut power use, as we explain in our post on installing a VSD drive to save power.
5. Book an Energy Audit
If the easy wins are done and the bill is still high, an audit shows where the power goes. Our electricians look at the equipment, lighting and cooling, then provide a written report with the issues we found and a plan to fix them.
The audit is a paid service, charged at our standard hourly rate. See our energy efficiency audit page for what is included.
Generate Your Own Power With Solar
Many Darwin businesses use most of their power during the day, which suits solar well. Panels can cover some of the daytime use, and we can add a battery to store extra for later.
We design every system around the premises and the people using it. Read about our solar installation service to see what suits your property.
Where to Start
Nobody has to do everything at once. We recommend working through these steps in order, because the biggest gains come first.
- Introduce a closing routine to switch off unused equipment.
- Walk the premises and note which lights run longest.
- Replace the worst offenders with LEDs.
- Service your air conditioning so it runs efficiently.
- Book an audit if the bill is still higher than it should be.
Frequently Asked Questions
How can a business use less electricity?
Start with habits and lighting. Switch off unused equipment at the wall, make good use of daylight and replace old lights with LEDs. Then look at cooling, which often runs the longest hours in Darwin. If the bill is still high, an energy audit shows where the power goes.
Does equipment on standby use power?
Yes. Computers in sleep mode, monitors, printers and kitchen appliances can keep drawing power while idle. The amount is small for each device, but it adds up across a workplace. A switched power board makes it easy to turn a whole desk off at once.
Are LED lights worth it for a business?
Usually, yes, especially where lights run for long hours. LEDs use far less power than halogen or incandescent lights and last much longer, so you save on both power and replacements. Our electricians can advise on which fittings to upgrade first during a visit.
Is an energy audit worth it?
It can be if your bills are high and you are not sure why. Our electricians review your equipment, lighting and cooling, then provide a written report with the issues found and a plan to fix them. It is charged at our standard hourly rate.
