I would tell people to enjoy the oil drop while it lasts. This may be long gone by Memorial Day. Why? A few reasons:
1: China is a very thirsty nation. They are also extremely rich and about to embark on infrastructure improvements that make the US's highway structure look like building a McDonalds. So, the demand for oil will be from them. Yes, US demand is in the 1990s levels... but with China guzzling the oil barrels, total demand is a lot higher.
2: Venezuela leaders and others are in Russia today. People forgot about 1972 and 1973 and the US oil embargo, which destroyed the economy until the 1980s. This can easily happen again. OPEC tends to get the prices it wants, and even though fracking might have increased supply, most of the wells done this way are depleted or near depletion, so the "golden" era of this is ending, especially with states like New York banning it wholesale. So, supply will go back down, and OPEC will ensure it stays down.
3: China is building their own canal across the Americas. This way, they can get their oil from Venezuela a lot more easily, completely bypassing any influence from the US.
4: Congress changed. Already, the solar subsidies are on the chopping block, and in January 2017, it won't be a surprise when the next President yanks the solar panels off the White House. Big Oil is now firmly in control of the US again.
5: The Keystone XL pipeline and a repealing of the ban on selling US oil overseas are pretty much guaranteed to happen. This means that any US oil will be trading at world prices.
6: As always, we are always one incident from price spikes. Should someone have a heart attack at a refinery, prices for crude will be back in the triple digits.
7: Alternative energy has grown, but most people's cars are still fueled by gasoline or diesel. If we had more electric cars, they effectively run on solar, wind, coal, nuclear, geothermal, hydro, or many sources. However, internal combustion engined vehicles require fossil fuel to run, and barring a major battery development, will continue to do so.
To, tl;dr... it is nice to have gas prices as low as they are, but they are going to be back to what they were in 2008, if not to $5-$6 a gallon by the summer. Oil prices are controlled by supply and demand, and demand is high due to a thirsty China, and supply is easily removed from the market.
