About Mario Alberto Arrastía Avila
Mario is responsible for the development and delivery of energy education at all levels within Cuba. His focus is on renewable energy, energy efficiency and climate change. He currently produces a weekly “Energy and Climate Change” program shown on national television as well as writing articles on renewable energy for national newspapers. Mario is a passionate and engaging speaker.
Why someone from Cuba?
(Report from Trevor Berrill) I recently visited Cuba, driven by interest in their music and culture, but also in their “Energy Revolution”. Cuba is one of the first countries to have experienced a major loss of oil supply, when almost 70 percent of its oil supply stopped with the collapse of the Soviet Union in 1989. This had a huge impact on food production and availability, and their transport and electricity systems. As well, climate change, in the form of extreme category 5 cyclones in recent years, has caused havoc on the electrical transmission system and other infrastructure. This reached a peak in 2003-05 with major shortages of power across the nation.
Cuba has responded in several ways. One is their “Energy Revolution”, which is a radical shift to a distributed grid system, energy efficiency, renewable energy systems and a “shared” transport system. To support this policy, in 2007, the “Central Group of Renewable Energies and Energy Efficiency was created and nowadays it embraces fifteen groups that are working in outlining national strategies to develop renewable energy technologies.” (Source: Arrastia-Avila et al)
The other is their adoption of permaculture agricultural practices to help provide fruit and vegetables through local cooperatives in towns and cities across the nation. “With the collapse of Soviet trade, Cuba sought another pathway for urban development which included the importation of one million bikes from China, to reduce the dependence on oil imports, and the program to establish urban gardens. This development process is more closely identified with ecologically sustainable development than any other nation in the world.” (Source: ACF). These structural changes are elements that many of us promote as part of a more sustainable future.
Cuba has a long history of both development and use of renewable energy technologies including wind pumps, hydroelectric systems and biomass fuel from sugar cane. These recent events have helped formulate a “much clearer vision, on the part of the high level officials of the country, with regard to the importance of renewable sources of energy and energy education of the society for the sustainable development of the country.” (Source: Arrastia-Avila et al). Cuba now has both PV and solar water heater manufacturing plants. Some examples of systems are shown below:

Benefits to Funding Groups
The benefits to groups which provide support are:
- Cuba is in some aspects a model of sustainable development for other developing countries due to its high education levels, health system and housing support for its people, and now its adoption of renewable energy and energy efficiency, and a distributed grid. Australia could learn from these measures and use this information to both transform its own unsustainable development pattern and assist developing countries likewise.
- Cuba’s ability and experience in preparing for and responding to extreme climatic events such as cyclones is well organized and very effective for a poor country. Their distributed electricity system has greater resilience now. We can learn from this. Our electricity system by comparison is very vulnerable, with a high dependence on large centralized plant and a long distance, above ground, transmission system. Nowhere is this clearer now than in Queensland where recent floods and category 5 cyclones have threatened this system, causing restricted access to coal supply to power stations and failure of major transmission lines.
- Cuba’s energy education programs are progressive and far sighted. Our environmental educators and government sponsored community educators can learn from Cuba’s experience in environmental education and social change.
- Cuba presents an opportunity for Australian professionals to exchange knowledge and skills across a range of areas, including RE and EE technologies, environmental education and social change.
Cuba and Australia have much to share through any industry exchange forum. Cuba has adopted renewable energy for both stand-alone and grid-connected applications. It has undertaken a massive energy efficiency campaign, changing to compact fluorescent lamps and energy efficient appliances virtually overnight. There are lessons to be learnt from this.
This tour is being sponsored and supported by the following groups to date:
- Australian Green Development Forum
- Townsville City Council
- Australian Solar Energy Society (AuSES)
- Alternative Technology Association (ATA)
