There were three big oil crises in twenty century, and all made international political shakes. The global warming triggered the climate change, the rising of sea horizon and other environmental problems. The advanced countries begin to think about decreasing the dependency of fossil fuels as economic grows. Both the Kyoto Protocol in 1997 and the United Nations Copenhagen Climate Change Conference in 2009 were the evidences that most of the countries in the world are all concerned about climate change and economical environments. Furthermore, the Kyoto Protocol and the United Nations Climate Change Conferences affected the global economic policies, and also generated new ideas of green economy. Because of the impacts from the environmental and economic view, many countries made new green energy policies to develop renewable energy, promote green industry, wake up environment protection ideas, and broadcast the education of save energy saving and carbon reduction. This thesis uses the historical method, content analysis method and comparative method and the public policy theory as the theory basement. Then the thesis introduces the summary of global green energy industry. Taiwan and Singapore are called as Four Asian Little Dragons, but both lack of nature resources and depend on energy importation. The thesis discusses the policies on green industry of the Taiwan and Singapore, and also discusses the outputs of the policies. The final part is the policy comparisons between the two governments.

The study covers oil and the power it entails and focuses on oil interdependence, oil-related conflicts and crises and macroeconomic effects. This thesis aims to examine the global oil industry's trade structure, to clarify the international geopolitical situation in the oil industry, and to analyze the effects of fluctuations in price on a macroeconomic level. The research has an explorative but also descriptive nature and can be classified as a correlational study. The thesis is mainly based on qualitative references obtained from interviews supplemented with quantitative data. The majority of conflicts in the Middle East can be classified as oil related, with a major impact on oil prices as a result. Oil price fluctuations correlate with and influence the macroeconomic situation in different countries, and the degree of the correlation varies due to the extent certain countries depend on oil. Interdependence is thus a significant factor in economic and geopolitical development. The study contributes to a deeper understanding and a more profound knowledge regarding global impact due to oil interdependence. This thesis indicates that the integration of oil in today’s society increases the world’s vulnerability to changes in the oil industry and therefore, oil contributes to power. / Denna studie omfattar oljans makt och fokuserar på beroendeförhållanden, oljerelaterade konflikter och kriser samt makroekonomiska effekter. Uppsatsen syftar till att undersöka den globala oljeindustrins handelsstruktur, kartlägga det internationella geopolitiska läget inom oljebranschen samt analysera oljeprissvängningars direkta effekter på ett makroekonomiskt plan. Studien har en explorativ men även deskriptiv karaktär och kan klassificeras som en sambandsstudie. Undersökningen baseras på kvalitativa källor genom intervjuer och kompletteras med kvantitativ data. Flertalet konflikter som ägt rum i Mellanöstern är oljerelaterade vilket har resulterat i betydande effekter på oljepriset. Oljeprisförändringar påverkar och korrelerar med det makroekonomiska läget i enskilda länder, hur stark denna korrelation är beror dock av i vilken utsträckning ett land är beroende av olja. Beroendet är alltså en betydande del i ekonomisk och geopolitisk utveckling. Studien bidrar till en ökad förståelse och en fördjupad kunskap i oljeindustrins beroendeförhållanden och dess globala påverkan. I studien framgår att oljans integrering i samhället gör världen sårbar för förändringar i oljeindustrin, olja bidrar därför till makt.
