Climate change threatens the efficient production of energy and given the high dependence on foreign energy sources across all sectors, this could increase Jamaica's overall economic vulnerability. Jamaica's energy mix is made up of 90% imported oil with the balance of 10% from renewable energy sources. In 2008, the amount of oil imported was approximately 27 million barrels (US$2.7 billion), a third of which was used by the bauxite/alumina sector with the remainder used in the 'domestic economy'. Since 2009, there has been a reduction in oil imports leading to a total of 20.24 million barrels imported in 2012 (at a cost of US$2.21 billion). Among the factors contributing to the lower consumption were conservation measures adopted due to the high cost of energy and the stagnation or decline of economic activities. The sector remains the largest user of foreign exchange and so it is incumbent on the country to reduce its dependency on oil as well as its emissions of greenhouse gases. This can be achieved by taking actions for mitigating climate change through abatement options, in particular, conservation and renewable energy production and use. Under Jamaica's National Energy Policy 2009 - 2030, Jamaica aims to increase the percentage of renewables in the energy mix with proposed targets of 12.5% by 2015 and 20% by 2030. Strategies and actions proposed in the policy include: develop diversification priorities based on cost, efficiency, environmental considerations and appropriate technologies and competitiveness;
