What You'll Learn

Estimate daily appliance usage
To estimate the daily usage of your appliances, you can use a few different methods. Firstly, you can estimate the number of hours per day an appliance is used. This can be done by keeping a usage log or by making a rough estimate if you know how much you use the appliance. For example, if you watch TV for roughly 4 hours a day, you can use that number for your estimate.
Another method is to use an electricity usage monitor. These devices can measure the electricity usage of any 120-volt device. They are available at most hardware stores for $25-50. You can also refer to the Energy Guide label on your appliance, which provides an estimate of the average energy consumption and the cost to operate that specific model.
If you want to calculate the daily energy consumption of an appliance, you can use the following formula: (Wattage x Hours Used Per Day) / 1000 = Daily Kilowatt-hour (kWh) consumption. For example, if you have a device with a wattage of 360W that you use for 15 minutes per day, the calculation would be: 360W x (0.25 hours / day) / 1000 = 0.09 kWh.
You can also use online electricity calculators to help estimate the power consumption of your electrical appliances and identify areas where you can reduce your usage.

Use an electricity monitor
If you want to know your annual electricity usage, you can use an electricity monitor. These are available at most hardware stores for $25-50. They are easy to use and can measure the electricity usage of any device that runs on 120 volts. However, they cannot be used with large appliances that use 220 volts, such as electric clothes dryers, central air conditioners, or water heaters.
To use an electricity monitor, simply plug it into the electrical outlet that your device uses, and then plug the device into the monitor. It will then display how many watts of electricity the device is using. If you want to know how many kilowatt-hours (kWh) of electricity the device uses over a certain period, you can just leave everything set up and then read the display later.
Some monitors will let you enter the amount your utility charges per kilowatt-hour and provide an estimate of how much it costs to run the device since it was plugged into the monitor. This can be useful for finding the amount of kWh used over any period of time for devices that don't run constantly, like refrigerators.
Monitors can also be used to estimate the "phantom loads" of energy that many appliances continue to draw when they are switched off. Most phantom loads will increase the appliance's energy consumption by a few watt-hours. These loads can be avoided by unplugging the appliance or using a power strip and using the switch to cut all power to the appliance.

Understanding your electricity bill and costs can help you manage your energy usage and save money. Here are some ways to gain a better understanding of your billing and costs:
Access Your Usage Data
You can access your electricity usage data through your energy provider's website or app. Log in to your account and navigate to the relevant section, such as "My Energy Usage" or "My So Tariff," to view your estimated electricity and gas consumption. Some providers also allow you to download usage data for further analysis.
Monitor Your Usage
Energy providers often offer tools to help you monitor your energy usage. For example, PG&E provides Energy Alerts, notifying you when your energy use is about to exceed your personalized statement alert amount. You can also install electricity usage monitors, available at most hardware stores, to measure the electricity usage of any device that runs on 120 volts. These monitors are especially useful for devices that don't run constantly, like refrigerators, and can help you estimate the cost of running these appliances.
Analyze Your Usage Patterns
By analyzing your energy usage patterns, you can identify areas where you can save. For instance, you may discover that certain appliances consume more energy than others, or that your energy usage spikes during specific times of the day or year. This information can guide you in making informed decisions to reduce your consumption and costs.
Compare Rate Options
Energy providers typically offer various rate plans or options. By comparing these options, you can choose the most cost-effective plan for your needs. For instance, you may benefit from enrolling in Peak Day Pricing if you can shift some usage away from weekday afternoons.
Explore Energy-Saving Measures
In addition to rate plans, energy providers often suggest energy-saving measures. These can include adjusting your thermostat settings during different seasons, switching to energy-efficient appliances and LED light bulbs, and unplugging electronics when not in use. Implementing these suggestions can help lower your energy consumption and, consequently, your bills.
By utilizing these methods, you can better understand your electricity billing and costs, enabling you to make informed choices to optimize your energy usage and manage your expenses.

Reduce usage with smart tech
Smart home technology can be a great way to reduce your energy usage and lower your electricity bills. Here are some ways you can use smart tech to reduce your energy consumption:
Smart Lighting
Smart lighting systems can be controlled via Wi-Fi, mobile apps, or smart assistants. They can save energy by switching to more energy-efficient LED bulbs, and by allowing you to control the brightness and colour of the bulbs in different rooms. You can adjust the lighting according to your comfort, and also save energy by dimming the lights when a bright light is not required. Motion-activated lighting is another smart lighting feature that can prevent wasted electricity in unoccupied spaces.
Smart Thermostats
Smart thermostats can adjust the temperature based on your daily habits and can be controlled remotely. They can also detect inefficiencies, so electricity waste can be minimised. In the winter, the most energy-efficient temperature for your thermostat is 68 degrees Fahrenheit. In the summer, set it to 78 degrees. Whenever you’re away from home, you should lower or raise your thermostat’s setting so you aren’t paying to heat or cool an empty house.
Smart Power Strips and Plugs
Smart power strips can manage devices that are often left on standby, such as televisions and game consoles. They can cut off power to these devices when they’re not in use, reducing phantom energy drain. Smart plugs can be used to manage the energy consumption of whatever you plug into them. Their apps let you program times of use, turn on and off power remotely, and even view your total energy consumption.
Energy Monitoring
Smart home systems provide real-time data on energy consumption, allowing you to identify which devices use the most energy and adjust their use or settings to save power. This can help you make informed decisions about which devices to unplug or replace with more energy-efficient models.
Smart Appliances
Smart appliances like washing machines, refrigerators, and coffee makers can notify you if there is a problem, allowing you to get repairs done quickly and potentially preventing the cost of completely replacing your appliances. For folks who pay different electrical rates for peak times, your dryer can even let you know when you’ll be charged the least amount for drying your clothes.
