To date no technical-economic-environmental review has been carried out on the use of hybrid wind-solar power plants in Japan. The study reported in this paper used HOMER soft- ware to analyze the electricity supply from renewable energy systems at 198 stations in Japan. The ranges of wind speed and solar radiation of the locations are 1.6-12 m/s and 2.723- 5.435 kWh/m2-day, respectively. The results show that the average, maximum and minimum use of renewable energy in Japan are 96.2%, 100% and 89%, respectively. Also, the av- erage, maximum and minimum cost per kWh of energy are $ 0.434, $ 0.526, and $ 0.249, respectively. The cheapest wind turbine system (the cheapest renewable energy system), the cheapest solar system, the cheapest hybrid wind-solar system, and the most expensive hybrid system, have a price per kWh of energy $ 0.294, $ 0.349, $ 0.339 and $ 0.526, respectively. These systems are located at Fuji Mountain, Minamitorishima, Iwojima and Tokyo, respectively. [ABSTRACT FROM AUTHOR] |
