要旨
Excessive usage of fossil fuels and high emission of greenhouse gases have increased the earth’s temperature, and consequently have changed the patterns of natural phenomena such as wind, wave, etc. Renewable energy resources are proper alternatives to mitigate the negative effects of increasing greenhouse gas emission, global warming and climate change caused by fossil fuels. About 71 percent of the Earth’s surface is water-covered, and the oceans hold about 96.5 percent of all Earth’s water. Moreover, around two-thirds of all the population lives within 100 kilometers of a coastline. Hence, marine renewable energies are massive resources to provide parts of the energy demand in areas adjacent to open water bodies. Among them, waves have the highest density and lowest visual and environmental impacts. However, wave energy is highly sensitive to change of the climate which alters the wind magnitude and pattern and consequently, the wave climate. Future plans for the commercial usage of wave energy in high potential areas need a lower uncertainty to reduce the financial risks of investments. In addition, installment of wave energy converters (wave farms) in nearshore areas can provide an additional advantage of the coastal protection. However, the impact of climate change and sea level rise on coastal areas cannot be neglected. Hence, the combined effect of climate change and installment of wave farms is required to be investigated in planning for future sustainable development.
