Maine is the most petroleum-dependent state for home heating, with more than 7 in 10 households using fuel oil as their primary heating source during the long, cold winters.
Crude oil is unloaded at the Port of Portland and sent through the Portland-Montreal pipeline to refineries in Quebec and Ontario.
Biomass—i.e. plant material and animal waste—accounts for more than one-fifth of Maine's net electricity generation, the largest share by far of any state. In rural Maine, the use of wood for home heating has increased as the price of home heating oil has risen.
Nearly 80% of the energy consumed in Maine is imported from other states.
