When the world reaches peak oil, it will be an entirely new experience for us all with the exception of one small country. Cuba has already had a “peak oil” experience imposed on them, with the collapse of the Soviet Union in the early '80s. All their supplies of oil were cut off and they were thrust into a national emergency of food and energy shortages.
How they survived that period in their history and actually created new systems of efficient, sustainable energy and food production is the subject of The Power of Community. Forced to rediscover the bicycle for transportation; oxen and horses for farming; smaller-scale, organic farms and urban micro-farms for raising food; and neighborly cooperation for solving their crisis locally they have paved the way for thriving in the new era of oil scarcity and $4 dollar gallons of gas. A very inspiring and beautifully told story.
