Without electric fans, the heat was almost unbearable in a country that regularly has temperatures in the 80s and 90s.
The solutions to Cuba's energy problems were not easy. Without money, it couldn't invest in nuclear power and new conventional fossil fuel plants or even large-scale wind and solar energy systems. Instead, the country focused on reducing energy consumption and implementing small-scale renewable energy projects.
Ecosol Solar and Cuba Solar are two renewable energy organizations leading the way. They help develop markets for renewable energy, sell and install systems, perform research, publish newsletters, and do energy efficiency studies for large users.
Ecosol Solar has installed 1.2 megawatts of solar photovoltaic in both small household systems (200 watt capacity) and large systems (15-50 kilowatt capacity). In the United States 1.2 megawatts would provide electricity to about 1000 homes, but can supply power to significantly more houses in Cuba where appliances are few, conservation is the custom, and the homes are much smaller.
About 60 percent of Ecosol Solar's installations go to social programs to power homes, schools, medicals facilities, and community centers in rural Cuba. It recently installed solar photovoltaic panels to electrify 2,364 primary schools throughout rural Cuba where it was not cost effective to take the grid. In addition, it is developing compact model solar water heaters that can be assembled in the field, water pumps powered by PV panels, and solar dryers.
A visit to "Los Tumbos," a solar-powered community in the rural hills southwest of Havana demonstrates the positive impact that these strategies can have. Once without electricity, each household now has a small solar panel that powers a radio and a lamp. Larger systems provide electricity to the school, hospital, and community room, where residents gather to watch the evening news program called the "Round Table." Besides keeping the residents informed, the television room has the added benefit of bringing the community together.
"The sun was enough to maintain life on earth for millions of years," said Bruno Beres, a director of Cuba Solar. "Only when we [humans] arrived and changed the way we use energy was the sun not enough. So the problem is with our society, not with the world of energy."
Transportation - A System of Ride Sharing
Cubans also faced the problem of providing transportation on a reduced energy diet. Solutions came from ingenious Cubans, who often quote the phrase, "Necessity is the mother of invention." With little money or fuel, Cuba now moves masses of people during rush hour in Havana. In an inventive approach, virtually every form of vehicle, large and small, was used to build this mass transit system. Commuters ride in hand-made wheelbarrows, buses, other motorized transport and animal-powered vehicles. Next > 1 2 3 4 5 6 7 8
