Why Is My Electricity Bill So High?

Are Solar Panels Worth It

Have you ever experienced the shock of opening your energy bill and finding it much higher than expected? It's a perplexing situation that many homeowners and renters face.

Understanding the factors that contribute to a high electricity bill is essential for managing your energy consumption effectively. Below, we will explore some common reasons behind unexpectedly high electricity bills and provide practical tips to help you reduce your energy costs.

1. Energy Consumption Patterns:

One of the primary reasons for a high energy bill is excessive energy consumption. Take a moment to reflect on your daily routines and lifestyle. Are you leaving lights on unnecessarily? Do you have multiple electronic devices constantly plugged in? Are you running appliances during peak hours? Identifying and modifying energy-intensive habits can significantly reduce your electricity consumption.



  • Develop energy-conscious habits, such as turning off lights when not in use and unplugging idle electronics.
  • Opt for energy-efficient appliances and replace old, inefficient models.
  • Utilise power-saving modes and timers on devices to reduce standby power consumption.


2. Seasonal Variations:

Seasonal changes can impact your electricity bill. Extreme temperatures require more energy to maintain a comfortable living environment. During summer, air conditioners consume a significant amount of power, while heating systems do the same during winter. Heating or cooling large spaces, improper insulation, and inefficient HVAC systems can contribute to higher energy consumption.

This is especially true in Australia, where many houses are weatherboard or similarly less insulated materials. Combined with biting cold winters and sweltering summers, comfortable living is going to have an impact on power bills.



  • Adjust your thermostat settings to energy-saving levels.
  • Ensure proper insulation in your home to prevent energy loss.
  • Consider using fans or natural ventilation before resorting to air conditioning.
  • Regularly maintain and clean your HVAC systems to ensure optimal efficiency.

3. Electricity Price Increases:

If your spike in electricity bills seems higher this billing period than the last few, the energy price increase in Australia that occurred 1 July 2023 could be to blame.

Energy bills rose on average between 25% to 45% across the country, with Victoria, New South Wales and South Australia suffering the heaviest blows.

The main driver of the price increase is a surge in wholesale prices. Both coal and gas are limited resources - and when supply can’t meet demand, the price can surge. Right now, a shortage internationally is driving up the price of the fossil fuels needed to generate traditional energy. The government has therefore permitted energy retailers to pass this increased cost on to its energy consumers (that means you).



  • Get in touch with your energy provider to enquire about how much they have increased your costs by since 1 July 2023
  • Find out if you still have the most competitive rates on the other side of price hikes. Remember, switching energy retailer is a task you should undertake at least every six months to ensure you are getting the best rates.
  • Install a solar and battery bundle to get away from power companies and energy providers entirely

4. Appliance Usage:

The appliances in your home can consume a substantial amount of electricity, especially if they are outdated or not energy-efficient. Older models of refrigerators, washing machines, and dishwashers tend to use more power. Additionally, leaving appliances on standby mode or forgetting to turn them off completely can contribute to unnecessary energy drain.

The primary offenders for driving up energy bills include dryers, dishwashers, and air conditioner systems. The impact of your appliances can increase further if they aren't energy efficient models. For example, a heat pump dryer is a type of clothes dryer that consumes far less electricity than a traditional vented dryer.

Outdated hot water tanks are another common cause of a higher bill.


  • Upgrade to energy-efficient appliances with high Energy Star ratings.
  • Wash clothes in cold water and let them air dry when possible.
  • Run the dishwasher and washing machine with full loads.
  • Unplug appliances when not in use or utilize power strips with switches.

5. Lighting Choices:

The type of lighting you use in your home can also affect your electricity bill. Traditional incandescent bulbs consume more energy and have a shorter lifespan compared to energy-saving alternatives like LED bulbs. Additionally, keeping lights on for extended periods without any occupancy sensors or timers can contribute to increased energy usage.


  • Replace incandescent bulbs with energy-efficient LED or CFL bulbs.
  • Make use of natural light during the day by opening curtains or blinds.
  • Install occupancy sensors or timers to automatically turn off lights when not in use.

6. Hidden Energy Drains:

Unbeknownst to many, several hidden energy drains in our homes can contribute to high electricity bills. Phantom loads, which are the energy consumed by devices on standby mode, can account for a significant portion of your bill. Common culprits include phone chargers, gaming consoles, and desktop computers.


  • Unplug chargers and electronics when not in use.
  • Use smart power strips that can cut off power to devices in standby mode.
  • Conduct an energy audit to identify and address hidden energy drains.

To Sum Up:

Understanding the factors behind a high electricity bill empowers you to take control of your energy consumption. By adopting energy-efficient practices, modifying daily habits, and making smart choices regarding appliances and lighting, you can significantly reduce your electricity expenses. 

If you want to stop worrying about your energy use entirely without seeing a higher bill, consider getting your home onto solar power. Not only will you save money, but you will also be liberating your household's relationship with simple everyday energy usage. Heat your home in winter, pop the dryer on half full, and leave the night lamp on for your child guilt-free.
