What nation is the most sustainable in the world? If you guessed Sweden or Denmark, you would be wrong. Instead, the World Wildlife Fund (WWF) has declared Cuba as the only country on the planet that is approaching sustainable development. Key to this designation is the island's Revolución Energética, an energy conservation effort launched only two years ago.
The WWF's Living Planet Report 2006 assesses sustainable development using the United Nations Development Programme's (UNDP) Human Development Index (HDI) and the ecological footprint. The index is calculated using life expectancy, literacy and education, and per capita GDP.
The UNDP considers an HDI value of more than 0.8 to be high human development. According to the ecological footprint, a measure of human demand on the biosphere, 1.8 global hectares per person or less denotes sustainability. The only country in the world that meets both of the above criteria is Cuba.
From Blackouts to Efficiency
Just a few years ago, Cuba's energy situation was bleak. This communist nation of 11 million people had 11 large, inefficient thermoelectric plants that functioned less than half of the time. There were frequent blackouts and high transmission line losses. Adding to the crisis, most Cubans had inefficient appliances, 75% of the population cooked with kerosene and residential electrical rates did not encourage conservation.
In 2004, back-to-back hurricanes slammed into Cuba, leaving a million people without electricity for 10 days. In the face of an antiquated system, violent storms, peak oil and climate change, Cubans realized that they had to make energy a priority. Thus, in 2006, they embarked on their Revolución Energética.
Only two years later, the country consumes 34% less kerosene, 37% less LPG (liquefied petroleum gas) and 80% less gasoline. Cuba's per capita energy consumption is one-eighth that in the US, while Cubans' access to health services, education levels and life expectancy rival those of their North American neighbors.
Prior to the 1959 Cuban revolution, only about half of the country's population had electricity. By 1989, that number had risen to 95%. After 1991, however, food, gas and oil all became scarce as a result of the collapse of the Soviet Union and the US economic blockade. This time came to be known as the "Special Period" because Cubans had to learn how to produce more of their food, medicines and energy locally and sustainably.
In the mid-1990s, Cuba embarked on a drive to save energy and use more renewables. All rural schools, health clinics and social centers not previously connected to the grid were supplied with solar energy, making lights, computers and educational television programs accessible to all students. This program garnered Cuba the Global 500 award from the United Nations in 2001.
