Abstract

Energy and electricity demand in Riau Islands is increasing rapidly due to the fast-growing population, urbanization, industrial development, and economic growth. The limitations of energy and electricity in the Riau Islands caused frequent blackouts. To support the high demand for energy and electricity in the Riau Islands, renewable energy is the most suitable alternative energy solution. Renewable energy is not only playing a key role in providing energy but also providing long-term clean and sustainable energy. We investigated the wave energy potential in the Riau Islands Sea in four different consecutive monsoons (North monsoon, East monsoon, South Monsoon and West Monsoon) using ECMWF data during January 2018 to December 2018 with 0.125o x 0.125o and 6 hourly spatial and temporal resolutions. We extracted bathymetry data from NOAA’s database ETOPO1 and forecasting wave characteristics use the SPM (Shore Protection Manual) method. The potential wave energy simulation from significant wave height (Hs) and energy period (Te) was shown in spatial distribution based on different monsoon. Our studies found that the potential wave energy was higher in north monsoon with maximum spatial of wave power density 3.240 – 3.640 kW.m-1. The east monsoon tended to be lower potential wave energy with dominance of wave power density at 0 – 0.127 kW.m-1. Keywords: wave power density, potential wave energy, ECWFM, monsoon

Highlights

Global energy still depends on the use of fossil fuels more than 80% of the total gross primary energy used in the world community (Buchanan, 2018) and this condition gives negative impact on our environment
It is difficult to change the world of fossil energy dependence, the renewable energy would be the most suitable alternative as the primary energy in the future, when renewable energy is present as increasing world energy demand (T et al, 2015)
Wave energy is very promising and is one of the most abundant energy sources in the world and has the highest energy density (Ilyas et al, 2014). This energy has the secondlargest potential of all renewable marine energy sources to development (Thorpe, 1999; Ilyas et al, 2014; Aderinto & Li, 2018) with an estimated less than 20% which is only exploited from sources of total wave energy in the world (Salter, 1973; Mørk et al, 2010; Mustapa et al, 2017; Wahyudie et al, 2017)

Summary

Introduction

Global energy still depends on the use of fossil fuels more than 80% of the total gross primary energy used in the world community (Buchanan, 2018) and this condition gives negative impact on our environment. The increasing concern with the negative effects of fossil fuels has pushed the world to find alternative sources of clean and sustainable energy as the requirement of the electricity demand (Ilyas et al, 2014). The exploration for a clean and sustainable energy source becomes very important and critical, but at the same time the use of fossil fuels is still difficult to suppress (Buchanan, 2018). It is difficult to change the world of fossil energy dependence, the renewable energy would be the most suitable alternative as the primary energy in the future, when renewable energy is present as increasing world energy demand (T et al, 2015)
