| Summary: | 碩士 === 國立臺灣海洋大學 === 應用經濟研究所 === 102 === Fossil fuel is going to be exhausted, Taiwan needs alternative energies such as renewable energies to replace fossil fuels for power generation and support economic growth. Taiwan is surrounded by the ocean that has the potential to develop the ocean and wave energy. This paper will focus on the UK marine power transmission company OPD (Ocean Power Delivery) attenuator wave energy power generation which names “Pelamis” to assess the possibility of developing the industrial and economic influence in Taiwan. Input-output analysis is quite suitable for energy, environment, pollution issues to evaluate the industrial development policies and overall economic impact assessment. This study adopts the input-output analysis to evaluate that the impact on the overall economic development, industrial assessment analysis and financial analysis. Results may support decision maker to invest on the ocean technologies in the future.
The results reveal that when adding an ocean wave energy industry in input-output table by year 2013, the output of economics will increase by 203 million dollars, the GDP will increase by 42 million dollars. The multiplier effect is 4.7405, bring additional multiplier effects in other industries are 3.7404; while the 2013 wave energy industry itself increases by 42 million dollars. Promoting policy of investment ocean wave energy sector by government’s investment (scenario I) will increase 13.66 billion of the output. The GDP will increase 2.89 billion. Addition to wave energy industry, but also indirectly promote other industries, electronic components, chemicals, iron and steel sector has been effect. The research also calculates the emission of CO_2which using wave energy instead fossil diesel and shows that will reduce 188,742.96 tons of CO_2 in 2013-2025 period.
Furthermore, use Pelamis investment cost information for financial assessment in scenario II. The results showed that 20-year total cost of the investment Pelamis present value is 200,178,383 NT dollars, 20-year present value of the total operating income is 253,921,603 NT dollars. NPV is 53,743,218.7 NT dollars, which reveals that Pelamis is a feasible and affordable option in Taiwan. By the sensitivity analysis results, the discount rate of 8%, the cost of electricity is 6.04 dollars per kWh, while the discount rate increased to 16%, the cost of electricity increased to 9.87 dollars per kWh.
