Being endorsed by Castro is sort of like being endorsed by the Ku Klux Klan or the Scientologists. Lots of people will use the peculiar ideas of the endorsers as a reason to dismiss Peak Oil as a nutty idea that is possibly evil. We need to lose this quote and endorsement of our ideas before Fox News picks it up. It's kinda like sleeping with a fat person-a whole lot of fun until your friends see you with 'em.

Way too late for that, dude.  Cuba has been embraced as the answer to peak oil by many environmentalists, liberals, and peak oilers for years now.  

I prefer to point to Switzerland during WW II, where they went through a 6 year, 100% oil embargo.  By 1845, they had "powered down" their oil use by ~93% while continuing as a functioning democracy and preserving a decent, if difficult, quality of life.

They made a strategic decision in the 1920s to electrify their railroads and preserve & expand their tram lines, all running off domestic hydroelectric power.

Wood gasifiers for transport and Ag
Per reports from a Swiss source, "some thousands" of wood source cars or tractors.  They were not common.

They also were hard on the engines.

VERY little transportation via rubber tires (emabrgo there as well) except bicycle and electric trolley bus.

Hand labor? in country oil reserves? Horses and oxen? for food production. I don't think that they had electric tractors...How people moved in towns doesn't interest me as much as ag.  Without ag...?
In country food reserves, most Swiss agriculture is alpine (i.e. herding).  Every square meter was hand planted in cities & towns.  Nearby areas suitable for row crops were tilled by hand (also grapes & orchards).  And agriculture got the oil that was left over after the army training, police and medical uses.

Potatoes. for example, can be cultivated by hand quite effectively.

Maybe so. But Castro is talking sense.  
Like those other world leaders TPTB dislike immensely (Chaves, Morales, Ahmadinejad, Putin, Hu, etc) he has an annoying tendancy to to that from time to time.
