For how long? Cheaper prices = more consumption = the sooner we get to a supply demand crunch again. All of this talk isn't even a solution, but rather just punting the ball a few more years.
We do not have an immediately available alternative. We have to get by somehow RIGHT NOW. We aren't even talking about cheaper prices... We're talking about avoiding an economic collapse at worst and a long depression at best depending on how widespread these revolutions become, how much damage to oil infrastructure is done, how long they take to end, and who is left standing on the other side.
My solution is pretty simple. Declare it a "war" time type of mobilization and build as many nuke plants as we can as fast as we can. Convert as much of our energy use in all areas but particularly transportation to electric. Electric cars and trucks are not truly viable right now. Electric rail freight and bus/train transit are available and viable alternatives.
If we make electricity sufficiently less expensive then innovation and invention will provide the means to use it.
If we derive most of our energy from nuclear power then perhaps we can afford the more expensive refining of auto fuels from domestic sources?
We would all like to believe that solar, wind, and tidal energy sources will solve all our problems. But the technology is many years off.
