Continuing the trend, diesel and unleaded gasoline prices fell by a few cents this week according to the latest numbers from the U.S. Energy Department. The average price of diesel was down about 2.2 cents compared to the start of October and is 16.4 cents cheaper than it was a year ago at $3.73 per gallon. This is the 15th straight week the average cost of diesel has not risen while it is at its lowest level in more than two years.

The cheapest diesel average was found in the Gulf Coast region at $3.662. The highest average was in the West Coast region at $3.933 per gallon.

The Department of Energy expects the average price for diesel to continue to fall this year and into the next, according to their Short Term Energy Outlook report which was published last week.

The price of natural gas is expecting to fall in 2015 as well. Consumption and production are expected to increase.
