Consumption of electricity in Maryland

MIT Alumni for Climate Action
Maryland consumes about 66 TWh of electricity per year, of which 56 % is produced in-state and the rest imported from nearby states. Of the Maryland total, about 50 % results from fossil fuels, 40 % from nuclear, and 10 % from renewables, , including hydroelectric power and utility-scale solar photovoltaic generation (see US EIA and below). The use of fossil fuels results in annual production of about 93 mega metric tons of CO2e of GHG emissions. Maryland's per capita petroleum consumption is ranked among the lowest 5 states. (Nearly 9 out of every 10 barrels of petroleum used in the state are consumed by the transportation sector.) In 2018, Maryland started the second operating US liquefied natural gas export terminal.
