The green energy agenda has become one of the most important issues in international relations. Many island states of the Oceania have taken the course of green economy construction. The Caribbean states are in some way similar to the Oceania ones and have also made several steps towards greener future. Some of these states are tightly connected with international tourism, leading to the high dependence of their economies from touristic revenues. The article examines this interconnection, including economic component in the analysis. The major question of the article is how does (or doesn’t) tourism influence the development of green energy in the Caribbean states. The two major economies examined in the region are Cuba and Dominican Republic as the two examples of the totally different economic systems and approaches to the development of the green energy. The key findings of the article include such conclusions as the possibility of synergetic interdependence between tourism, economy and green energy and the positive effects this interdependence has. The other finding is that the Cuban method of introducing green energy is less effective than the Dominican one. The novelty of the article includes the comparison of the two economic models in the Caribbean and the development of strategies for the green energy proliferation in the countries.
