The price of heating oil continues to climb steadily in Maine even as global crude oil prices have fallen. The Governor’s Energy Office said Tuesday the average statewide cash price is now $2.99, which is 3 cents higher than a week ago. It’s also up from $2.21 per gallon from October 2017. The energy office says there has been “considerable speculation” about the future of oil prices due to impending economic sanctions on Iran from the United States.
