Trinidad and Tobago is the region's leading exporter of oil and gas but imports of fossil fuels provided over 90% of the energy consumed by its CARICOM neighbours in 2008. This vulnerability led CARICOM to develop an Energy Policy which was approved in 2013. This policy is accompanied by the CARICOM Sustainable Energy Roadmap and Strategy (C-SERMS). Under the policy, renewable energy sources are to contribute 20% of the total electricity generation mix in member states by 2017, 28% by 2022 and 47% by 2027.
