Power Profiler

How clean is the electricity you use?

Electricity is produced by many different sources of energy, including, but not limited to, wind, solar, nuclear, and fossil fuels. The type and amount of emissions produced depend on how electricity is generated in your region. Type in your zip code (or select a region) to view your power profile.?

Fuel Mix

(Reset sorting)

This chart compares fuel mix (%) of sources used to generate electricity in all eGRID subregions. Select a fuel to sort subregions by fuel.

Emission Rates

This chart compares the average emission rates in pounds per MWh ? in all eGRID subregions to the national average emission rates for carbon dioxide (CO2), sulfur dioxide (SO2), and nitrogen oxide (NOx).

Annual Results

Result Subheader

Using the eGRID subregion () emission rates and percent line loss, your estimated annual use of kWh of electricity results in pounds CO2, pounds SO2, and pounds NOx emitted in one year from the power plants in your area.

It would take seedlings grown for 10 years or acres of forests in one year to offset those CO2 emissions. EPA's Energy and the Environment site can show you how to take steps to reduce your environmental impact, such as becoming more energy efficient or switching to cleaner energy sources.

To find out more about what a reduction in your electricity use means in everyday terms, like miles driven, visit EPA's Greenhouse Gas Equivalencies Calculator and for basic information about GHG emissions, visit EPA's Greenhouse Gas Emissions site.

This is an estimate of the pounds of air pollutants caused by the electricity you use in your home or business during one year. Your annual emissions are estimated from the average home consumption of 1,011 kWh/month and the eGRID subregion () emission rates and include a grid region specific adjustment for line losses of percent. Estimate annual emissions for commercial customers here.

In the United States, electricity is generated in many different ways, with a wide variation in environmental impact. Electricity generation from the combustion of fossil fuels contributes toward unhealthy air quality, acid rain, and global climate change.

Many electricity customers can choose their provider of electricity or can purchase green power from their utility. In fact, you might now have the option of choosing cleaner, more environmentally-friendly sources of energy.

To compare the fuel mix (i.e., resource mix) and air emission rates of the electricity in your region to the national average and to determine the air emissions that result from electricity use in your home or business, either select the appropriate eGRID subregion or enter your ZIP code to determine the appropriate eGRID subregion.

Power Profiler does not provide information about the environmental attributes of electric power generated by individual companies. For company-specific information, access EPA's eGRID database.

The 26 eGRID subregions in the US are defined by EPA using data from the Energy Information Administration (EIA) and the North American Electric Reliability Corporation (NERC). The subregions are defined to limit the amount of imports and exports across regions in order to best represent the electricity used in each of the subregions. More information can be found in section 3.4.2 of the eGRID Technical Support Document.

A megawatt (MW) is a unit for measuring power that is equal to one million watts. A megawatt hour (MWh) is equal to 1,000 kilowatts of electricity being used continuously for one hour. One MWh is equivalent to the amount of electricity needed to light 10,000 100-watt light bulbs for one hour or the electricity needed to power an average home for a little over one month.
