Energy savings involve lower bills and increased energy efficiency. To optimize your home, you must first understand its efficiency.

This comprehensive guide will explain how to conduct a home energy audit, including what to look for, what equipment is required, and what professional services are available.

An energy audit can help you improve the efficiency of your home. You’ll identify which appliances to upgrade, save money on your energy bills, and make your home more comfortable to live in.

Here are some suggestions to get you started.

What’s a Home Energy Audit?

A home energy audit is a thorough check-up of your home’s energy use. It shows you where you can fix things to use less energy and spend less money.

It means examining different parts of your house, such as the stuff that keeps it warm and your devices, to see how well they use energy.

Getting ready for the audit: Before you start the audit, collect your old energy bills to see how much energy you usually use. This will help you see how much better you do after making changes.

Learn About Your Energy Usage

Check how much energy your home uses in kilowatts per hour and compare it to other homes around you.

If your bill shows you’re using a lot more energy than what’s typical for your area, especially by more than 10 kWh every day, it means you should really look into how your home uses energy. You can see what’s typical for your area.

Find Out Devices That Use Most Energy

Some everyday items that use a lot of electricity are outdated fridges, pool pumps, and heat pumps.

If you don’t have an energy meter to show your energy use, try switching off everything but the one device you’re testing and watching your energy meter. If the meter spins quickly, that device uses a lot of energy.

You can also work out how much electricity something uses by taking its wattage (usually on the bottom of it), multiplying by how long you use it each day, and then dividing by 1000 to get daily KWh.

Then, see how much it costs you each day by multiplying by the price you pay for each kWh from your bill.

Replace Old Appliances With Energy Efficient Ones

That old extra fridge might be costing you a lot of energy. New devices might use less power, so even though they cost money, you’ll save on your energy bills later on.

Look for ones with the best Energy Star Ratings, but remember, different items are rated based on different things they do. You can figure out how much it might cost to run new appliances online.

Focus On LED Lighting

Change out old lights for LED lights that use less energy. Also, try not to use downlights, as they can let warm air escape from your room.

Instead of heating or cooling your whole house, choose systems that can change the temperature in just the room you’re using.

Put in Good Insulation and Air Control

If your insulation isn’t excellent, you’ll have to run your heater or AC longer. Find out if you have the proper insulation for your area.

Look Out for Leaks:

The first thing you can fix in your house is drafts—like cracks where the floor meets the walls or where the walls meet the ceiling. Check outside, too, where different materials are put together in your house.

Remember to check your windows, doors, lights, pipes, switches, and power outlets for any gaps that let air through.

Test for Air Leaks:

To really know where air is escaping, use a particular test called a Blower Door Test. It tells you exactly where your house is not sealed right so you can fix those spots. Even though it’s not perfect, you can do a simple test yourself to find leaks:

  • Wait for a chilly, breezy day.
  • Turn off anything that burns fuel (like heaters or water heaters).
  • Close all your windows, doors, and fireplace openings.
  • Turn on fans that blow the air outside, or use a big fan to pull air out of your rooms.
  • Light a stick that smokes and hold it near places where air might leak. If the smoke moves weirdly or gets blown or sucked in, you’ve got a draft. You can also use your wet hand to feel for cold drafts.

If you don’t want to turn off your fuel appliances, you can perform the test using your fans.

Other ways to find leaks:

  • At night, shine a flashlight over possible cracks while someone looks from outside. Big cracks will show as light beams. This only works well for tiny gaps.
  • Close a door or window on a strip of paper or money. If you can pull it out quickly, the air is probably leaking, and that’s wasting energy.

Heaters and Air Conditioners:

Check how old your heating and cooling system is. Older ones might not work as well, and they can leak air. Think about how you set your thermostat—more minor shifts are better for saving money.

Appliances:

Find out how old your big machines, such as your refrigerator and laundry machine, are and check how much power they have.

What are Some Energy-hungry Areas in Your Home?

  • Some common examples of energy-guzzling appliances that may be contributing to high electricity usage in a home are:

    Old refrigerators: Older fridge models are often less energy-efficient than newer ones.

    Clothes dryers: Tumble dryers, especially older models, use a significant amount of energy to dry clothes.

    Air conditioners: Inefficient or old air conditioning units can consume a lot of energy, mainly when used frequently or for cooling large spaces.

    Space heaters: Portable electric heaters can use a lot of power, mainly if they’re used as the primary heat source in a home.

    Pool pumps: Pool pumps that circulate and filter water continuously can be significant energy consumers.

    Water heaters: Traditional tank-based water heaters keep water hot 24/7, which can add to your electricity bill.

    Ovens and stoves: Older electric ovens and stovetops can be inefficient and use a lot of energy during cooking.

    It’s important to note that the actual energy consumption for each appliance will vary based on usage patterns, the model’s efficiency, and other factors.

Process of Individual Audits

Cooling

In Australia, using air conditioning takes up a considerable amount of our power bill—about 40%—so we have to stay cool wisely.

Step 1: Pick the right temperature: Is your aircon set to 25-27 degrees Celsius? If you go just 1 degree colder, you could use up to 5-10% more energy.

Remember, different territories have different weather conditions in different places. The Red Centre can swing from hot to cold, while the Tropical North has a rainy season and a dry season.

Depending on where you are, you might need to change how warm or cool you set your aircon, especially during winter.

Step 2: Clean out the dirt: Remember to clean your air conditioner’s filters regularly. This helps it run smoothly without having to work too hard.

Step 3: Fix any leaks: Leaks or blockages can make your air conditioner less efficient, and constant use can wear it out. When was the last time you had it checked? It’s good to have a professional look at it once a year to keep it in tip-top shape.

Step 4: Keep the heat out: To prevent too much heat from getting inside, consider getting curtains with a white lining that blocks light for your oversized windows.

Appliances

In some households, gadgets like fridges and washing machines can use up to 30% of all the energy the house needs.

Step 1: Keep track: Pay attention to which gadgets you use most often.

Step 2: Switch off: Look around. If you’re not using something, is it turned off at the wall? Get used to flipping the wall switch to off after you use something, rather than leaving it on all the time or in ‘standby’ mode.

Step 3: Dry in the sun: The Northern Territory’s sunshine is ideal for drying clothes. To save energy, hang laundry outside instead of tossing it in the dryer.

Step 4: Full loads only: Be smart about how you use your washing machine and dishwasher. Take your time running them when they’re not complete. Wait until you can fill them up to start a cycle. Doing fewer loads means using less energy and water.

Hot Water

Using a hot water heat pump uses up about 23% of your home’s energy, so it’s essential to think about that when you’re trying to use less energy.

Step 1: Hot Water Temperature: What temperature is your hot water at? It’s best to keep it between 60 °C and 65 °C.

Step 2: Short Showers: Try to take quicker showers to save water and the energy needed to heat it. Try to keep it under 4 minutes.

Step 3: Stop Leaks: If you have taps that drip, get them fixed.

Step 4: Old Water Heaters: If your water heater is old, think about getting a new one, like one powered by solar energy or one with a 5-star energy rating.

Step 5: Efficient Shower heads: Swap your shower head for one with a 3-star rating or higher.

Refrigeration

When the weather’s warm, some appliances, especially fridges, have to work extra hard and end up using more electricity.

Step 1: Seals Check: Check the seals on your fridge to keep the cold in and the heat out. TIP: Close the fridge door on a piece of paper. If the paper slides out quickly, you might need new seals.

Step 2: Right Temperature: Set your fridge temperature between 3 °C and 5 °C.

Step 3: Space for Air: Make sure there’s room behind your fridge so air can move around.

Step 4: Second Fridge: Think about how often you use your second fridge. If it’s not frequent, you might not need it.

Lighting

Lighting your home accounts for approximately 6% of your total energy usage. Turning on lights and then forgetting to turn them off can cost you money.

Step 1: Replace traditional light bulbs with fluorescent or LED lights.

Step 2: Work with a licensed electrician to remove any unnecessary light fittings around your home.

Step 3: Use sensors and timers, particularly for outdoor lighting.

Australia 943 MW Project, Bermuda Offshore Plans

Australia has approved the 943 MW Valley of the Winds Wind Farm, Bermuda plans to install an offshore wind farm with 17 turbines by 2027, and Nova Scotia proposes an ambitious $10 billion offshore wind project.

Australia has given the green light to a massive wind project. The Independent Planning Commission in New South Wales has approved ACEN Australia’s nine hundred forty-three megawatt Valley of the Winds wind farm. The project also includes a three hundred twenty megawatt battery storage system. The project will create up to four hundred construction jobs and fifty permanent positions. The investment is approximately one point six eight billion Australian dollars.

The island nation of Bermuda is making the most of its windy weather. Officials unveiled plans for an offshore wind farm starting with seventeen turbines by twenty twenty-seven. The project aims to help Bermuda reach its twenty thirty-five goal of eighty-five percent renewable energy. The project will begin with a sixty megawatt installation near the north shore. Officials hope to scale up to one hundred twenty megawatts total.

Nigel Burgess, head of regulation at Regulatory Authority Bermuda, calls offshore wind a compelling opportunity. The project will lower exposure to fuel price shocks and create space for long-term investment. Currently, Bermuda gets one hundred percent of its power from fuel burning. The project aims to promote energy independence by reducing dependence on imported fuels. The wind farm is expected to be operational by twenty thirty.

Nova Scotia has announced an ambitious offshore wind project that could cost up to ten billion dollars. Premier Tim Houston wants to license enough offshore turbines over the next ten years to produce forty gigawatts of electricity. That’s eight times more than originally planned. To put this in perspective, Nova Scotia with just over one million people requires only two point four gigawatts at peak demand. China’s offshore wind turbines were producing just under forty-two gigawatts as of last year.

The project would require hundreds of wind turbines built in water about one hundred meters deep, about twenty-five kilometers offshore. Experts say the project would actually need more than four thousand offshore turbines using current fifteen megawatt turbines. The transmission line alone is estimated to cost between five billion and ten billion dollars to connect the wind farms with the rest of the country.

The premier calls it a concept to capture the imagination of Nova Scotians. He wants federal help to cover costs, saying the excess electricity could supply twenty-seven percent of Canada’s total demand.

California a “Failed State?”

Published

Disgusting. It’s one thing that “news” in the United States has largely been replaced by incendiary opinions. But it’s even worse that so many of these opinions are so grossly ill-informed.

In its quest to move to the middle of the political spectrum, CNN has integrated a few hard-right commentator, like Jennings.  Fine; I get that.  But do they have to be morons?

In particular, can’t CNN do better than to refer to California as a “failed state?”  If California were a nation it would be the fourth largest economy on the planet, having recently overtaken Japan.

North Carolina needs more certainty before committing to an expensive new gas plant

Published

on

Despite massive uncertainty across the economy, Duke Energy is plowing ahead with its plan to build new fossil gas-fired power plants to serve data center, manufacturing, and other large customer load that may not even show up. Duke has asked the NC Utilities Commission for permission to build a combined-cycle (CC) gas plant in Person County, North Carolina, at the site of Duke’s Roxboro coal plant.

SACE has argued against the need for this gas power plant in the Certificate of Public Need and Necessity (CPCN) docket, submitting testimony to the Commission on Monday, June 9, 2025. Here’s a summary of that testimony (prepared by Synapse Energy Economics, Inc.), which explains what this all means for Duke’s billpayers, and how Duke can make changes within its control to protect customers and reduce pollution. These recommendations include:

  • Not approving this new gas power plant because the risks that it will increase bills are too high. Instead, Duke should improve the processes that are holding back lower-cost renewables and storage, then use renewables and storage to meet new load.
  • Instead of approving this specific gas plant, the Commission should order Duke to use an all-source procurement process to determine a portfolio of flexible assets that can meet the utility’s needs based on real-world costs.
  • In the event the Commission approves this gas plant, it should protect customers from high bills due to volatile gas prices by instituting a fuel cost sharing mechanism for the fuel costs spent to run this plant.

Duke Doesn’t Need this Risky Gas Power Plant

Duke’s claim that it needs this fossil gas power plant is based on outdated analysis. In this CPCN docket, Duke relies on its 2023 Carbon Plan Integrated Resource Plan (CPIRP) modeling and the CPIRP supplemental update and analysis filed in January 2024. The world has changed dramatically since then, and it is important that the Commission review the latest information before approving expenditures that will impact customer bills for decades.

Duke’s load forecast – once based on steady, predictable growth – is now subject to significant uncertainty as 1) data center developers look around the country for the best deal and the fastest interconnection to the grid and 2) manufacturers announce projects and then pull back as political uncertainty changes the economics of those projects. Under Duke’s current rate structure, prospective companies and site developers do not need to commit much money to become part of Duke’s load forecast. They have very little “skin in the game,” and Duke currently does not have policies in place to change this. If the Commission allows Duke to build an expensive fossil gas plant for load that doesn’t materialize, Duke’s remaining customers will be on the hook to pay for it.

Duke’s own load forecast updates since 2023 show that there are wild swings in its predictions. In the Spring of 2023, Duke anticipated 8 new large load projects during its 10-year planning forecast period, requiring an average of 169 MW each. Then for Fall 2023 (the supplemental update filed in January 2024), Duke anticipated 35 projects requiring an average of 111 MW each. In Summer 2024, Duke changed its forecast again, projecting 39 projects requiring an average of only 103 MW. And in May 2025, Duke filed an update showing a reduction in the number of projects back down to 35 but a dramatic increase in average need – back up to 169 MW. Duke’s forecasts will continue to show swings up and down – both in the number of projects and megawatts – until Duke has policies in place that require more commitment from the companies that knock on its door requesting service. Duke also has not published information regarding the location of these loads – the latest forecast applies to all of Duke Energy in both North and South Carolina.

It is also important to know that that this gas plant isn’t needed to meet growing load from existing customers or to replace retiring coal plants (according to Duke’s own testimony). This gas plant is being justified by new manufacturing and data centers claiming they will be operating somewhere in Duke Energy Progress or Duke Energy Carolinas territory in North or South Carolina.

Even if the load shows up, this plant won’t be needed for long

Even Duke admits that it doesn’t “need” this fossil gas power plant for very long. These kinds of power plants, combined-cycle plants, are typically used about 80% of the time, i.e. they are “baseload” power plants. But even absent federal carbon regulations, Duke expects this power plant’s usage to decline significantly throughout its 35-year lifetime (from 80% in 2030 decreasing to 46% by 2040 and only 13% by 2050 onwards). As cheaper renewables and storage with zero fuel costs are brought online, they will displace this plant. Duke is proposing to build a giant power plant that will very quickly run less and less – but Duke’s customers will continue to pay for it until 2065—15 years past a state law requiring Duke’s generation fleet to be carbon neutral. This represents a significant change in how power plants are built and run, and this is not in the best interest of Duke’s billpayers. To add insult to injury, Duke hasn’t even procured all of the equipment needed to build this plant, so the costs could skyrocket even more than they already have since last year’s carbon plan proceeding.

Renewables are flexible, would protect customers, and would reduce pollution

Duke’s model only chose a gas plant to meet this capacity need because of limits Duke imposed on the model. Duke claims it cannot interconnect renewables and storage fast enough to meet this capacity need, but the reasons it cannot interconnect those resources faster are all within Duke’s control. As Synapse recommends, Duke needs to update its processes that are holding back renewables and storage from serving customers with low-cost and low-risk resources. These processes include interconnection and transmission planning.

SACE has been advocating for improvements to these processes for years, and Duke has made changes to both its interconnection process and transmission planning. Duke was one of the first utilities in the Southeast to implement cluster studies in its interconnection process, and it is in the midst of the first scenario-based transmission planning exercise in the region. But is there evidence that these updates have helped if Duke continues to limit solar and storage in its future resource modeling? Given the much quicker interconnection process recently demonstrated in Texas, this raises the question of how hard Duke is really trying to streamline renewables interconnection.

Modular, flexible resources such as wind, solar, and energy storage can be adjusted in quantity based on market conditions. As our testimony from Synapse states, “This modularity, combined with the fact that solar and wind have zero exposure to fuel price volatility once they are constructed, makes these resources particularly valuable in the face of trade tariff uncertainty.”

The bottom line is that the Commission needs a lot more certainty about load growth and costs before committing Duke’s billpayers to any type of large fossil gas power plant. We simply do not have that now.
