How To Calculate Electricity Usage In Australia

How to Calculate Electricity Usage?

One of the most important first steps in controlling your household's energy use and lowering your carbon impact is figuring out how much power you consume. By following the step-by-step instructions provided below, you can take charge of your power consumption, reduce your electricity costs, and help create a more sustainable future.

Step 1: Gather the Necessary Information

To begin calculating your electricity usage, you'll need some basic information:

Step 2: Calculate Daily Electricity Usage

Use the following calculation to get your daily power usage:

Total Electricity Usage (kWh) ÷ Number of Days in the Billing Period = Daily Electricity Usage (kWh).

For instance, if the billing month lasts 30 days and your total power use is 600 kWh, your daily electricity usage would be: Daily Electricity Usage = 600 kWh ÷ 30 days = 20 kWh per day.

Step 3: Determine Peak and Off-Peak Usage (if applicable)

If your tariff is time-of-use, meaning that different prices apply during peak and off-peak hours, you will have to compute how much you consume during each period independently. You can find out the peak and off-peak tariff timings by looking at your power bill or contacting your provider.

Step 4: Identify High-Energy Appliances

Certain appliances use more power than others. Find the high-energy appliances in your house to better understand how much power you use. Refrigerators, water heaters, washing machines and air conditioners are frequently the causes. Make a note of these appliances' power usage or wattage ratings. These details are available in their user manuals or nameplates.

Step 5: Estimation of Appliance Usage

Next, calculate the approximate daily use time for each high-energy equipment. For instance, the daily consumption of each appliance would be as follows: if you used the washing machine for one hour, the air conditioner for four hours, and the refrigerator for twenty-four hours.

Air Conditioner: 4 hours/day × Air Conditioner's Wattage (W) = X kWh/day

Washing Machine: 1 hour/day × Washing Machine's Wattage (W) = Y kWh/day

Refrigerator: 24 hours/day × Refrigerator’s Wattage (W) = Z kWh/day.

Step 6: Total Electricity Usage

Add up the daily usage of each high-energy appliance to the daily electricity usage you calculated in Step 2: Total Electricity Usage (kWh) = Daily Electricity Usage + X kWh/day + Y kWh/day + Z kWh/day

Step 7: Regular Monitoring and Energy Conservation

Make it a habit to check your electricity use after you thoroughly grasp it routinely. Check your power bills every month to spot any odd trends or surges.

Step 8: Monitoring Tools and Smart Meters

Using smart metres and monitoring tools can help you measure your power use more effectively. Numerous energy companies have smartphone applications or websites that let you track how much electricity you use in real-time. Using these tools, you can determine peak use periods and monitor how much power you're using at any given time.

Modern gadgets called "smart metres" have replaced conventional power metres. They provide comprehensive information on how much energy you use, usually every 30 minutes. By evaluating this data, you may optimise your energy use and obtain important insights into your usage habits..

Step 9: Energy-Efficient Upgrades

You may find that some of your appliances need to be updated and more efficient when you monitor how much power you use. Upgrade to more energy-efficient ones; over time, they may help you save a lot of energy and money on power bills.

Seek out appliances bearing the ENERGY STAR logo, which signifies that they adhere to stringent government-established energy-saving regulations. High-efficiency LED light bulbs are another easy and affordable update that may result in significant energy savings.

Step 10: Conduct an Energy Audit

A home energy audit can reveal many places to increase your energy efficiency. Either perform a do-it-yourself audit or engage a qualified energy auditor. Inspect insulation, look for air leaks around windows and doors, and evaluate how well your heating and cooling systems are working. Making the required adjustments in light of the audit's findings may result in long-term cost and energy savings.

Step 11: Be Mindful of Phantom Load

Phantom load, often referred to as standby power or vampire power, is the amount of electricity used by appliances and other electronic equipment even while in standby mode or switched off. Small quantities of electricity are still needed for these gadgets to keep their settings or to be operational. Even if each gadget uses very little electricity, the total impact might be substantial.

Consider utilising power strips, which make it simple to turn off several devices simultaneously to prevent phantom load. When not in use, unplugging computers, chargers, and other devices can also help cut down on needless energy use.

How Much Do Appliances Cost Your Electricity Bill?

Knowing how much electricity you use at home and how to calculate its costs can make your everyday budget easier to manage. By being aware of how electricity usage is calculated and taxed, you may make wise decisions to conserve money and energy.

Look up the amount you pay per kWh, or your electric rate, on your most recent account to get an idea of how much an appliance would cost to your power bill. Multiply your electric rate by the projected monthly use from the previous step to get the monthly cost of your appliances.

Monthly Cost = Monthly Usage (kWh) x Electric Rate ($/kWh)

An example would be a television that uses 15.3 kWh monthly for $0.16 per kWh for electricity. $0.16 x 15.3 kWh = $2.44 for the monthly bill

A list of average wattages of typical household devices is also supplied. This might provide you with a ballpark estimate; however, the wattage of your specific device may differ.

Appliances That Use More Electricity

The following appliances use the most electricity in your home. You can reduce their usage to save more energy bills.

Air Conditioners: Typically, an air conditioner uses 1,000-5,000 watts per hour. When the weather is hot, turn up the temperature on the air conditioner to reduce its power use. To prevent overusing your air conditioner, choose one appropriate for the size of your space.

Electric Room Heaters: These have a power consumption range of 750–1500 W/h, with larger or baseboard units perhaps reaching 2000 W/h. Ensure you have warm clothes or electric blankets, or use them sparingly indoors.

Electric Water Heaters: They often require 3,500-4,500 watts per hour. To retain the heat, turn the thermostat to 120°F (49°C) and insulate your heater and pipes.

Clothes Dryer: It has an hourly capacity of 1,800 and 5,000 watts. The best defence against overconsumption is to prevent over-drying clothing. Hang your clothes outside on a line in the sunshine.

Electric Stoves & Ovens: They consume 5,000-10,000 watts per hour. Therefore, you may use smaller appliances for simple activities like covering pots and pans to retain heat. Moreover, slow cookers allow you to save power.

Electric Kettles require 1,000-1,500 watts per hour to boil water. Boil only as much as is necessary in the kettle rather than filling it up every time. To prevent overheating, use an electric kettle with several temperature settings or a stovetop kettle.

Tips to Reduce Your Electricity Bills

Lowering your power costs so you can use the money for savings or other essentials. Additionally, it can aid in reducing your carbon footprint and promoting environmental sustainability. Here are four primary aspects to think about:

Utilise Energy-Saving Settings

The majority of contemporary devices and appliances include energy-saving modes or settings. Switching to cold water for your washing machine or turning on power-saving mode on your computer can gradually reduce your energy consumption.

Implement Energy-Efficient Habits

Water Heating and Laundry: Ensure the tariff for your electric hot water is regulated load or off-peak. When doing laundry, use cold water and the appropriate cold water detergent. Fill the washing machine to the brim and select economy wash to save electricity.

After every load, clean the lint filter in the clothes dryer. Avoid combining heavy and light clothing, as they require different drying times. Try not to use the dryer as often as possible. Alternatively, you may use an indoor rack beside a window or the sun to dry your garments.

Air Conditioning & Heating: Your energy consumption may rise by 5% to 10% for every degree you choose to chill or heat more. Open your windows and doors, use fans to generate cross breezes, and move cold air about. Shut the doors, windows, curtains, and blinds to keep the air inside the spaces you wish to heat or cool.

For cooling, your air conditioner should be adjusted between 24°C and 26°C. Choose a temperature setting for heating between 18°C and 20°C. Clean the filter twice yearly to keep your air conditioner operating as effectively as possible.

Kitchen: The most energy-intensive appliance is your refrigerator, which runs on an on/off cycle every day. Restricting the amount of time the refrigerator door is open will help to keep the food cool. Refrigerator and freezer seals should be cleaned and replaced if necessary. 

Make sure your dishwasher is fully loaded and set on the economy setting. When not in use, turn off small appliances at the power outlet. While shopping, go for gadgets that use less energy.

Lighting: In Australian houses, household lighting accounts for roughly 6% of the power bill.

Replace your outdated light bulbs with more energy-efficient models, such as LED or compact fluorescent lights, to save your lighting expenses by more than 80%. These solutions are also five to ten times more durable. Place reading lamps next to chairs to prevent lighting up the entire room. During the day, employ natural illumination by opening the curtains and blinds.

Consider Renewable Power

Australia has a great chance to use renewable energy sources because of its abundant sunshine. By installing solar panels on your roof, you may produce energy and become less dependent on the grid. This lowers your carbon impact and reduces your power costs. 

Furthermore, a few energy suppliers allow you to sell any extra electricity your solar panels produce back to the grid through feed-in tariffs. This benefits you and the environment.
