Historically (~60 year trend) US $/Gallon adjusted for inflation averages long term around ~$2.50 Gallon (based on 2012 $dollar).

But there have been up to +40% highs and -40% lows in the fluctuations.

Soo I expect it to continue to track on a long term average roughly with inflation .. but with those + and - fluctuations on shorter periods of time.

The absolute value of the magnitude of those +/- fluctuations I expect to roughly fit a bell curve.

Long run ... over 50 years down the road .. I also expect BEV will replace oil as a transportation fuel (2σ) .. and over 100 years down the road I expect RE to replace fossil fuels in general (2σ).
