I want to understand my energy use

Confused by your energy bill? Want to have a better idea of what uses the most energy in your home, how much you are using, and what you’re paying?

There are different sources of energy in Maryland 

Did you know that there are many different sources that supply the state with our electricity? Power plants can generate electricity from fuel resources like nuclear, coal, and natural gas or renewable energy sources such as  waterheatwind, and the sun. You can find a statewide profile overview by visiting Energy Information Administration (EIA)

Maryland Public Service Commission also created a video that provides a closer look at specific elements of energy choice: “How are electricity and gas delivered to our homes and businesses? And how do the energy choices we make affect how this happens?”

Your energy choices help Montgomery County reach its goal.

It might not seem like much, but every little step you take to conserve energy and become more energy efficient helps Montgomery County get closer to reaching its Greenhouse Gas Emissions goal of reducing greenhouse gas emissions – 80% by 2027 and 100% by 2035. Track our goals and progress.

As a Maryland resident, you have the option to choose who supplies your electricity.

Maryland is an energy choice state where customers can choose their electricity and natural gas providers. Some suppliers regularly offer rates and service that are 10% or more cheaper than the utility company.

If you have questions about switching, the Energy Supplier Help Desk is a partner with the Energy Supplier Reform Coalition in Maryland. The tips and information offered are by volunteers who help consumers understand their bills and third-party supplier plans and choices.

If you choose your own supplier, there will be no change in the way your electricity or natural gas will come to your house – it will still be delivered to your home by your local utility company, but you can choose a less-expensive supplier to generate the energy and keep more money in your pocket.

  • SWITCH NATURAL GAS SUPPLIERS: The Maryland Public Service Commission has created a new website where consumers can shop for and sort offers to supply their home’s energy needs – whether they are seeking the lowest price per therm, environmentally-friendly gas supply, no monthly or early termination fees, www.MDGasChoice.com

Heating your home still uses the most energy. Even though energy use for air conditioning has doubled since 1980, appliances and electronics now officially account for nearly one-third of all the energy used in American households.

Take a look at the breakdown of energy use at Energy Use In Homes at EIA.gov.

The Department of Energy also has an appliance and electronic energy use calculator that allows you to estimate your annual energy use and cost to operate specific products.

What is the Home Energy Report?

Your Home Energy Report is another way the utilities help residents save money and energy. In support of the EmPOWER Maryland Energy Efficiency Act, encouraging Marylanders to reduce their energy use, they provide residents with a new tool to make saving money and energy simple.

​Understanding your energy use is the first step towards saving. With easy-to-read graphs, your Home Energy Report is designed to provide you with helpful information about the way your household uses energy and find smart ways to make your home more efficient.

Here’s how it works:

Occasionally, customers with smart meters installed at their home will receive a paper Home Energy Report in the mail. The frequency of this report will depend on your average energy use. If your utility has your email address on file, they will also send you a monthly eHome Energy Report with details about your monthly energy usage.

Neighbor Comparison

The report compares your energy use to 100 similar households in your community, based on public record.

Personalized Tips

You will receive tips on how to reduce your energy use, giving you opportunities to improve the numbers in your report.

Savings Goals

Set yearly goals and track your progress to see how your home’s energy usage changes over time and across seasons.
