There are many ways to waste a lot of electricity, some more obvious than others. Leaving lights on in empty rooms is a common way to waste electricity, as is using old incandescent light bulbs that use 90% of their energy as heat. Leaving appliances and electronics plugged in and running 24/7 is another way to waste electricity, as these devices can consume phantom power even when turned off. This can add up to 10% of a home's total electricity use. Not using a smart thermostat is also a waste of electricity, as heating and cooling account for about 52% of household energy use, and smart thermostats can help to reduce this by learning your habits and optimising energy use. Wasting electricity is bad for the environment and your wallet, so it's important to adopt energy-saving strategies and technologies to reduce your energy consumption.

What You'll Learn
Leaving the lights on
If you're looking to waste a lot of electricity, leaving the lights on is a great way to go about it. Here are some ways to maximise energy usage by keeping the lights on:
First, opt for incandescent bulbs. These are the least efficient bulbs on the market, with 90% of their energy given off as heat, and only about 10% resulting in light. This means that not only will you waste electricity by leaving these bulbs on, but you'll also increase your energy costs by making the room hotter, requiring more energy to cool it down. Halogen bulbs are a close second, as they use similar technology to incandescents but are slightly more efficient.
Second, forget to turn off the lights when you leave a room. Leaving lights on in unoccupied rooms is a surefire way to waste electricity. Even if you plan to return to the room soon, it's still worth turning off incandescent and halogen bulbs. For CFL or LED lights, it's generally recommended to turn them off if you'll be gone for more than 15 minutes.
Third, avoid natural light sources. Open blinds or curtains can illuminate a room without using any electricity, so be sure to keep them closed if you want to waste electricity by using artificial lighting.
Fourth, disregard energy-saving tips. Techniques such as using timers to automatically turn off lights, replacing incandescent bulbs with LEDs, and decorating with light colours to reflect more light can all help reduce energy consumption. By ignoring these tips, you can ensure you're wasting more electricity by leaving your lights on.
Finally, leave the lights on overnight. Not only will this add significantly to your energy bill, but it can also pose a safety risk. All types of bulbs can get extremely hot, potentially igniting nearby flammable materials. So, leaving lights on unattended can waste electricity and create a dangerous situation.
By following these steps and leaving your lights on, you can waste a considerable amount of electricity and drive up your energy costs.

Using incandescent bulbs
If you're looking to waste a lot of electricity, using incandescent bulbs is a great way to go about it. Incandescent bulbs are much less energy-efficient than newer LED bulbs, so they will help you rack up a high electricity bill.
Incandescent bulbs use about 60 watts of electricity, compared to LED bulbs, which use about 10 watts. This means that if you use an incandescent bulb for 2 hours a day, it will use about 12.2 kilowatt-hours of electricity per month and 43.8 kilowatt-hours per year. On the other hand, an LED bulb used for the same amount of time would only use about 0.61 kilowatt-hours per month and 7.3 kilowatt-hours per year.
The cost of running an incandescent bulb for 2 hours a day comes out to about $0.52 per month and $6.22 per year, while an LED bulb would cost about $0.09 per month and $1.04 per year. So, by choosing incandescent bulbs, you're looking at a much higher electricity bill.
To waste even more electricity, you could leave your incandescent bulbs on for longer periods. The more you use them, the more electricity they will consume. For example, running an incandescent bulb for 3 hours a day will use about 1.26 kilowatt-hours of electricity per week, 5.48 kilowatt-hours per month, and 65.7 kilowatt-hours per year.
Additionally, you could use incandescent bulbs in multiple fixtures or throughout your entire home. The more bulbs you have, the more electricity you'll waste. You could also choose higher-wattage incandescent bulbs, as they will consume more electricity.

Leaving electronics plugged in
Firstly, it is worth noting that not all devices are equal when it comes to standby power consumption. For example, an iPhone charger has a standby power consumption of 0.26 watts, while a laptop or desktop computer can consume up to 25 watts. However, chargers that are not charging anything still continuously consume about 1 watt in the socket, and this can add up over time, increasing your electricity bill.
Some devices with “soft” switches, such as a small-travel push button, will still draw a small amount of power even when turned off. This is because the power is still required by the electronics to monitor the button for when it is turned on again. Anything with a "standby" mode, remote control activation, or the ability to turn on at a particular time falls into this category. Devices such as televisions, cable boxes, game consoles, and chargers are common culprits of this.
To determine which devices in your home are drawing the most power, it is recommended to use a device such as a Kill-a-Watt, which can measure the energy usage of each appliance. Once you have identified the power-draining devices, you can make a more conscious effort to unplug them when not in use.
By unplugging devices, you not only save money on your electricity bill but also reduce your carbon footprint. In 2015, the Natural Resources Defense Council estimated that devices left on 24/7, even on standby, cost the average US household around $165 every year, amounting to $19 billion worth of wasted electricity across the country.
Therefore, leaving electronics plugged in can indeed waste a lot of electricity, and it is important to be mindful of our usage and unplug devices when they are not in use.

Powering an empty freezer
To waste a lot of electricity by powering an empty freezer, you can start by ensuring the freezer is not in an optimal location. Place the freezer near a heat source, such as an oven, radiator, or direct sunlight. This will cause the freezer to work harder and consume more energy. Additionally, avoid placing it in a well-ventilated area, as proper ventilation can help reduce energy consumption due to overheating.
Next, you can ignore any ice build-up in the freezer. Just 2 mm of ice can increase energy consumption by 10%. The more ice there is, the harder the freezer will have to work, resulting in higher electricity usage.
Another way to waste electricity is by keeping the freezer door open for extended periods. Each time the door is opened, warm air enters, and the freezer has to work harder to cool it down. Leaving the door open will cause the freezer to continuously attempt to maintain a stable temperature, leading to increased electricity usage.
You can also fill the empty freezer with non-food items that conduct heat well. Metal objects or containers filled with water can absorb and retain the cold, making it more challenging for the freezer to maintain its temperature. This will result in higher electricity consumption.
Additionally, you can set the freezer to the coldest possible temperature. Lower temperatures require more energy to maintain, so by setting it to an extremely low temperature, you will increase electricity usage.

Browsing the refrigerator
The refrigerator is one of the major culprits in spiking electricity units. A simple way to waste a lot of electricity is to leave the fridge door open for an extended period. This causes the internal temperature to rise, and the refrigerator has to work harder to cool the air inside, consuming more electricity.
To waste electricity, open the refrigerator door frequently and for long durations. Instead of planning ahead and gathering everything needed at once, open the fridge multiple times to browse for snacks. This will cause the compressor to run more frequently, wasting electricity.
Another way to waste electricity is to store a lot of food in the refrigerator, blocking airflow and vents. This will make the fridge work harder to cool everything down, leading to higher electricity consumption.
Additionally, placing items on top and sides of the fridge can also waste electricity. This hinders the release of hot air created during the cooling process, making the fridge work harder.
Finally, neglecting regular maintenance of the refrigerator can also waste electricity. Dirty condenser coils and loose door seals can cause the compressor to work harder, increasing electricity usage.
