What You'll Learn
Understanding your electricity bill
Electricity Rate
The rate on your bill is the amount paid per unit of electricity consumed, measured in kilowatt-hours (kWh). The average American home uses 914 kWh of electricity per month. The rate section of your bill details the cost of electricity per kWh. By knowing your rate, you can estimate how much energy you use over time and how much you can save.
Fixed-Rate and Variable-Rate Plans
Typically, you will have one of two types of rate plans: Fixed Rate or Variable Rate. Fixed-rate plans allow you to lock in a rate for a specified number of billing cycles, making it easier to estimate monthly supply charges and protect you from market price fluctuations. Variable-rate plans, on the other hand, fluctuate with the current market rate, making it more challenging to estimate monthly costs.
Additional Charges
Be aware of additional charges that may be included in your bill, such as tax fees, delivery fees, and service charges. Some companies also charge for paying bills online or by phone, as well as monthly fees for not enrolling in auto-pay options. These fees can impact your total bill, so it's important to review them and ensure they align with your budget.
Usage Profile and Meter Information
Your bill may include sections like Usage Profile and Meter Information, which provide details about your consumption patterns and how the meter data is incorporated into the calculation of your charges.
Solar Panel Impact
If you have solar panels installed, your consumption and costs will be significantly lower. Your bill will show how much electricity you pulled from the grid, as well as any net metering credits or incentives available.
Carbon Intensity
The carbon intensity of electricity refers to the amount of greenhouse gas emissions per unit of electricity produced. This value can vary depending on how the electricity is generated, with coal power plants having higher carbon intensity than renewable sources like solar or wind. Understanding the carbon intensity of your electricity can help you assess the environmental impact of your energy consumption.
By understanding the components of your electricity bill and monitoring your usage, you can make more informed decisions about your energy consumption and explore ways to reduce costs and environmental impact.

Using smart meters
Smart meters are advanced digital devices that record energy usage and transmit the information to the utility company, enabling accurate billing. They frequently include real-time monitoring and can show users how much energy they use hourly, weekly, or throughout the month.
Smart meters use current transformers to monitor the electrical current in a circuit and voltage transformers to measure the voltage. They calculate instantaneous power by multiplying the measured current and voltage. This instantaneous power is continuously recorded, providing a real-time representation of power consumption. The meter then integrates this data over time to determine the total energy consumption, usually expressed in kilowatt-hours (kWh).
Smart meters can also measure reactive power, which is the amount of power stored and released by the load due to its capacitance or inductance. They can communicate this data to the utility company and the customer, enabling more accurate billing, demand response, and energy efficiency. For example, a customer could monitor their electricity usage and costs in real-time, allowing them to adjust their usage in response to changes in prices or system reliability events.
Smart meters are being rolled out nationwide and internationally. In California, the CPUC authorized the replacement of conventional customer meters with Smart Meters to give consumers greater control over their energy use. With smart meters, customers can make informed decisions by providing highly detailed information about electricity usage and costs.

Tracking carbon intensity
Smart Meters
Smart meters are advanced digital devices that record energy usage and transmit the information to utility companies using radio signals. They offer real-time monitoring, providing insights into hourly, daily, and monthly energy consumption. Smart meters enable utility companies to accurately bill customers and help users identify areas where they can reduce their energy usage and associated emissions.
Electricity Maps
Platforms like Electricity Maps provide visual representations of grid carbon intensity in real-time. This allows users to understand the carbon intensity of their electricity supply, which can vary depending on the energy sources used in their grid. For example, coal power plants have higher carbon intensity, while renewable energy sources like solar and wind have lower carbon intensity.
Global Initiatives
Global initiatives like Carbon Monitor and CarbonTracker provide regularly updated, science-based estimates of carbon dioxide (CO2) emissions. Carbon Monitor makes its data freely available to the public, encouraging users to utilize the information for decision-making. CarbonTracker focuses on atmospheric carbon dioxide, tracking CO2 uptake and release at the Earth's surface, especially in North America.
Real-Time Data
Accessing real-time data on electricity grid intensity can help track and reduce emissions. This data enables a better understanding of how various patterns and disruptions impact the emissions footprint of electricity grids. Policy interventions, such as price signals and tariffs, can then be introduced to incentivize load shifting and reduce the climate impact of electricity consumption.
By utilizing smart meters, visual platforms, global initiatives, and real-time data, individuals, organizations, and policymakers can effectively track carbon intensity and make informed choices to reduce carbon emissions associated with electricity usage.

Analysing usage trends
You can also determine your peak usage hours by examining your electricity bills or utilising smart meters. Some bills provide information on peak usage hours, allowing you to shift your energy-intensive activities to off-peak times, thereby reducing costs. Smart meters offer real-time monitoring and provide insights into hourly, daily, and monthly energy usage, helping you identify trends and make informed decisions.
Another aspect to consider when analysing usage trends is the rate changes in your electricity bills. Pay attention to seasonal adjustments and varying rates based on location and time of year. This awareness can help you lower your energy use when necessary and make more energy-efficient choices during higher-rate periods. For instance, enrolling in Peak Day Pricing programs can lead to a lower electric rate if you can shift some usage away from weekday afternoons.
Additionally, it is essential to examine the fees included in your electricity bills, such as tax fees, delivery fees, and service charges. Understanding these expenses ensures that you properly budget for any surprise costs and identify areas where you may have limited control but need to account for them financially. By reviewing these fees, you can make informed decisions and potentially explore alternative options to optimise your energy usage and associated costs.

Using energy monitors
Energy monitors are a great way to understand your electricity usage and make your home more energy-efficient. They are small devices that are installed in your circuit breaker panel or electrical panel and connect to your electricity meter. Energy monitors can provide information on your energy usage at the appliance, circuit, or whole-home level, all remotely from your mobile device.
Some energy monitors, such as those included in smart plugs, monitor a single appliance at a time and give you a detailed view of that device's energy usage. For example, the Emporia Gen 3 Vue monitor uses smart devices and direct observations to measure how much power individual circuits are using. It also has an app that integrates with smart plugs, thermostats, appliances, and lighting to see how much power they use.
Household energy monitors, on the other hand, connect to your energy panel or individual circuits to provide a broader picture of your home's energy usage. For instance, Sense uses machine learning to identify individual appliances and their electricity usage. It takes a million measurements per second of your home's power usage to provide a detailed picture of your energy consumption. The Sense Home App is available for free if your electricity provider has installed a new Wi-Fi-enabled Smart Meter.
When choosing an energy monitor, it is important to consider your goals. If you want to track the cost of your energy consumption in real-time, make sure the monitor has this feature. Additionally, look for a monitor with a mobile app component that can provide notifications and insights to help you maximize cost savings.
