Owing to strong local winds and large elevation differences on the Hawaiian island of Maui, it may be a suitable place to combine a wind farm with pumped hydro energy storage. At times when the wind turbines produce excess power, water is pumped to reservoirs at higher elevations. The water is released during periods of high electric demand through hydraulic turbines to produce electricity. Develop a proposal to meet 30% of the island’s power needs by the year 2020 using this renewable energy concept. In your report, list advantages and disadvantages of the proposed system. Include at least three references.
