Analysis

Last Updated: December 21, 2023

Overview

Maryland wraps around the Chesapeake Bay and extends west into the Appalachian region, where the state's only fossil fuel reserves—coal and natural gas—are found.1 Baltimore, the state's largest city and one of the 20 largest ports in the nation, handles both coal and petroleum products.2,3 Maryland's renewable energy resources—hydropower, solar, wind, and biomass—are distributed widely throughout the state.4 Maryland is the seventh most densely populated state in the nation with 636 people per square mile. The state's population is concentrated in the center of the state in an area that stretches from the northeastern Baltimore suburbs southwest to the suburbs of Washington, DC.5,6 Maryland's western mountains and low-lying southern and eastern plains are largely rural and lightly populated.7 East of the Chesapeake Bay, in an area known as the Eastern Shore, the land is flat with many wetlands, and the nearby Atlantic Ocean adds humidity and moderates the weather year-round. On the western side of the Bay, the land rises from the coastal plain through rolling foothills to the mountain ranges of the Appalachians.8 Precipitation is fairly evenly distributed throughout the year and across the state, but, as the land rises to the west, temperatures generally decline and annual snowfall levels increase during the winter.9 The state's coastal areas average less than 4 inches of snow annually, while parts of the western mountains average more than 100 inches.10

Maryland consumes about five times more energy than it produces.

Maryland consumes about five times more energy than it produces.11 In 2021, the transportation sector accounted for 33% of the state's energy consumption, followed closely by the residential sector at 31% and the commercial sector at 29%. The industrial sector accounted for 7% of the energy used in Maryland. Maryland ranks among the 10 states with both the lowest total per capita energy consumption and the lowest energy use to produce one dollar of GDP.12,13,14 Major contributors to the state's GDP include: government spending; finance, insurance, and real estate; professional and business services; education and healthcare; and construction.15

Petroleum

Maryland has no economically recoverable crude oil reserves or production, and there are no petroleum refineries in the state.16,17,18 Some petroleum products arrive in Maryland by pipeline from other states and by ship from abroad. The Colonial Pipeline runs through Maryland on its way from the Gulf Coast to the New York City metropolitan area and delivers refined products to terminals in the state, including gasoline, diesel fuel, home heating oil, and jet fuel.19 Baltimore's deep-water port receives tankers carrying petroleum products from other countries.20,21

Maryland's total per capita petroleum consumption is the fourth lowest among the states, after New York, Rhode Island, and Massachusetts.22 About 8 out of every 10 barrels of petroleum used in Maryland are consumed by the transportation sector.23 The state requires the use of reformulated motor gasoline blended with ethanol to reduce smog-forming pollutants across the densely populated Baltimore-Washington corridor in the center of the state. Counties in the mountain west and much of the rural Eastern Shore are not required to use reformulated motor gasoline, although two counties on Maryland's Eastern Shore have opted to require the fuel.24,25 The industrial and residential sectors each account for about 5% of the state's petroleum consumption, and the commercial sector uses about 4%. A small amount of petroleum is used to generate electricity.26 About 1 in 10 Maryland households use heating oil, propane, or kerosene for heating.27

Natural gas

Maryland has few economically recoverable natural gas reserves, and the state produces very little natural gas.28,29 There are a few low-production wells in far western Maryland that collectively produce about 5 million cubic feet of natural gas annually.30,31 The state's two westernmost counties—Garrett and Allegany—overlie part of the natural gas-rich Marcellus Shale and have some recoverable natural gas reserves.32 However, in 2017, Maryland enacted a permanent ban on the use of hydraulic fracturing in natural gas and crude oil production.33

Maryland's natural gas needs are met by supplies that enter the state by way of several interstate pipelines and a liquefied natural gas (LNG) port. Major pipelines transport natural gas to the state from the nation's Gulf Coast and Southwest via Virginia. Increasing amounts of natural gas enter Maryland from the north through Pennsylvania, as that state's shale gas production continues to grow. Maryland's Eastern Shore also receives natural gas from Pennsylvania by pipeline through Delaware.34,35 About four-fifths of the natural gas that enters Maryland continues on to Virginia, the District of Columbia, or is liquefied for export to other countries.36

A small amount of natural gas enters the state at the LNG import terminal at Cove Point, Maryland, on the Chesapeake Bay's western shore. Cove Point is one of a dozen operating LNG import facilities in the United States.37,38 The terminal is connected by pipeline to several major interstate natural gas pipeline systems.39 Maryland's LNG imports from other countries decreased substantially during the past decade in response to increased U.S. natural gas production.40,41,42 With U.S. natural gas production rising, Cove Point became the second LNG export terminal operating in the United States in early 2018, and by late 2023 it was one of eight in the country.43,44

In 2022, Maryland’s electric power sector consumption of natural gas reached a record high.

Maryland ranks among the 10 states with the lowest per capita natural gas use.45 The electric power sector became Maryland's top natural gas-consuming sector for the first time in 2018. In 2022, the sector consumed a record amount of natural gas and accounted for about 36% of the state's natural gas use. Natural gas-fired electricity generation in the state has tripled since 2015.46,47 The residential sector made up 30% of Maryland's natural gas consumption in 2022, followed by the commercial sector at 27% and the industrial sector at about 6%. A minor amount of natural gas is used in the state's transportation sector.48 About 4 out of 10 Maryland households use natural gas as their primary fuel for home heating.49

Coal

Maryland holds about 0.1% of the nation's estimated recoverable coal reserves and accounts for about 0.3% of U.S. coal production.50,51 The state has 1 underground and 13 surface coal mines, all of them located in the Appalachian Basin in the state's western counties.52,53 Slightly more than half of Maryland's coal stays within the state and most of it is consumed at power plants. Almost all the rest is sent to West Virginia, where that coal is also used at electric power plants. A minor amount of Maryland coal is sent to Pennsylvania for use in steelmaking, and a small amount of coal is exported to other countries.54,55

Overall, coal-fired power plants use about four-fifths of the coal consumed in Maryland, and industrial plants use the rest. Pennsylvania provides about 53% of the coal consumed in Maryland, and almost all the rest comes from Maryland's coal mines. Most of Pennsylvania's coal arrives in Maryland by rail and truck, and Maryland coal is delivered within the state by truck. There are also minor coal shipments from West Virginia, Kentucky, and Ohio that arrive by rail and truck.56

Baltimore is the second-largest U.S. coal exporting port.

Coal is the leading export commodity by tonnage at the Port of Baltimore, the nation's second-largest coal export center after Norfolk, Virginia. In 2022, about one-fifth of the nation's coal exports left through Baltimore.57,58,59 Steam coal, which is burned to generate electricity, accounted for almost three-fifths of Baltimore's coal exports, and metallurgical coal, which is used in steelmaking, made up the rest.60 The Port of Baltimore historically received a small amount of imported coal each year, but it handled no coal imports in 2021 and 2022.61

Electricity

Nuclear energy and natural gas supplied 75% of Maryland’s total electricity net generation in 2022.

In 2022, nuclear energy and natural gas generated 75% of Maryland's total in-state electricity, with each supplying almost equal amounts of the power supply. Maryland's only nuclear power plant—the two-reactor Calvert Cliffs power plant located on the western shore of the Chesapeake Bay—accounted for about 39% of the state's total net generation.62,63 Natural gas-fired generation has more than tripled since 2015, as nearly 2,600 megawatts of new natural gas-fired generating capacity came online. Natural gas accounted for about 36% of in-state electricity generation in 2022.64,65

Coal-fired generating plants historically supplied more than half the state's net generation, but coal's share has been below 50% since 2012 and was at 12% in 2022.66 As of mid-2023, there were four generating units at Maryland's three remaining coal-fired power plants with a combined generating capacity of nearly 1,800 megawatts. The two largest power plants intend to stop burning coal by 2025 and the smallest plant will end its coal use in mid-2024.67,68 Solar energy, hydropower, wind, and biomass accounted for most of the state's remaining net generation in 2022.69 Since 2015, almost all of the state's new generating capacity has been natural gas-fired or solar-powered.70

Maryland uses less electricity per capita than about four-fifths of the states, but it uses about 40% more electricity than it generates, and the extra supply is delivered to the state over the regional grid.71,72,73 The residential sector accounted for about 47% of Maryland's electricity use in 2022, followed closely by the commercial sector at 46%. About 4 in 10 Maryland households use electricity as their primary heating source.74,75 The industrial sector accounted for 6% of the state's electricity consumption, and the transportation sector, consisting of railways and subway and light-rail systems in the Maryland suburbs of Washington, DC and in Baltimore, made up about 1%.76 Maryland had about 70,500 registered electric vehicles and about 1,300 electric charging stations by May 2023.77 The state provides financial incentives for consumers to purchase electric vehicles and for the installation of charging stations.78

Renewable energy

In 2022, solar power accounted for the largest share of Maryland’s renewable electricity generation for the first time.

Renewable energy, including both small-scale generating installations (less than 1 megawatt) and utility-scale generating facilities (1 megawatt or larger), provided 12% of Maryland's total in-state electricity in 2022. Solar power accounted for the largest share for the first time, slightly more than two-fifths, of the state's renewable electricity generation.79 Solar powered-generation more than quadrupled from 2015 to 2022. Nearly two-thirds of the state's solar generation came from small-scale, customer-sited solar photovoltaics (PV), such as rooftop solar panels, and the rest of the generation was at larger utility-scale solar farms.80 By mid-2023, Maryland had about 1,550 megawatts of total solar generating capacity installed.81 The state's largest solar facility—located on the Eastern Shore—came online in late 2022 with a generating capacity of 80 megawatts.82

Hydropower provided almost two-fifths of the state's renewable electricity generation in 2022.83 The Conowingo hydroelectric generating station, located in northern Maryland on the Susquehanna River, was the second-largest hydroelectric power plant ever built, after the Niagara Falls generating station, when it began operating nearly a century ago. The 11 turbines at the station have a combined generating capacity of 572 megawatts.84,85 Conowingo provides almost all of Maryland's generation from hydroelectricity and it is one of the state's top 10 power plants based on both generating capacity and actual annual generation.86

Wind energy provided slightly more than one-tenth of Maryland's renewable electricity generation in 2022.87 The state's best onshore wind resources are in its western mountains and along its southern Chesapeake Bay and Atlantic Ocean shorelines.88 The state's only operating utility-scale wind farms are along Maryland's western Appalachian Mountain crests, where 190 megawatts of generating capacity is installed.89 Maryland's greatest wind energy potential is offshore.90

Four major wind projects are in development off Maryland's Atlantic coastline. The MarWin wind project, located about 18 miles offshore in federal waters, will feature 22 turbines that will reach a blade tip height of about 900 feet, which is taller than the Washington Monument. Collectively, the turbines can generate up to 248 megawatts of electricity, and the project is scheduled to come online in 2026.91,92,93,94 The Momentum Wind Project, with 55 turbines and 809 megawatts of capacity, is planned 15 miles off the Maryland coast and is expected to be operational in 2026.95,96 The federal Bureau of Ocean Energy Management released for public comment in October 2023 an environmental impact statement on the two projects, a key step in the federal review and approval process.97 The Skipjack wind project, expected to come online in late 2026, is planned for two areas about 20 miles offshore from the Maryland-Delaware state line and have a combined generating capacity of nearly 1,000 megawatts from 69 wind turbines. All of Skipjack's generated electricity will be sent to Maryland.98,99,100,101

Biomass fueled about 7% of Maryland's renewable electricity in 2022, including at facilities that use landfill gas, municipal solid waste, and wood and wood waste.102 There are many small landfill gas-to-energy facilities in cities around the state. Maryland's largest biomass-fueled electricity-generating plants account for about 70% of the state's total biomass generating capacity. They are two facilities that use municipal solid waste: a 57-megawatt facility in Baltimore and a 54-megawatt facility in Montgomery County in the suburbs of Washington, DC.103 The Baltimore facility also produces steam for a downtown piping system that supplies heat to more than 250 businesses.104

Maryland updated its renewable portfolio standard (RPS) in May 2019, when the Maryland legislature required that 50% of the state's electricity retail sales come from renewable sources by 2030.105,106,107 As part of the updated RPS, 14.5% of a supplier's electricity retail sales must come from solar power by 2030. The RPS also requires that the state's offshore wind generating capacity reach 400 megawatts in 2026 and increase to at least 1,200 megawatts in 2030.108,109 Maryland's legislature enacted a separate law in 2022 to further reduce the state's greenhouse gas emissions to 60% below the 2006 levels by 2031 and to reach a net-zero emissions level by 2045. Maryland met an already existing target to cut greenhouse gas emissions 25% below the 2006 baseline by 2020, exceeding it with a 30% reduction. The new law also boosts energy conservation measures for buildings and requires the state government to buy zero-emission vehicles.110,111
