 (05.05, 07.02, 08.05 HC) Hydroelectric power can come from energy carried by ocean waves, tides, salinity, and ocean temperature differences. This energy can be harnessed to generate electricity. Figure 1—Tidal Turbine   Reference Figure 1 to answer the following: Explain how tidal turbines can create electrical energy to power homes. Describe one effect the tidal turbine may have on the ocean environment. Describe one possible impact tidal turbines can have on the biodiversity of ecosystems. Propose a strategy to avoid the impact described in (iii). Justify your solution by explaining a potential advantage. Ocean energy has the potential of providing a large amount of renewable energy around the world. Explain the advantage of using this renewable energy source over other renewable energy options. Globally, an estimated 1,800 TWh of tidal energy exists per year. There are several tidal power plants around the world, including large ones in South Korea, France, and Canada. The largest tidal plant produces 0.5 TWh/year, which can power 46,000 homes annually. Calculate the number of homes that can be powered by 50 TWh of energy. Calculate the number of tidal plants needed to power 92,000 homes annually.
