Power Generation Using Ocean Waves: A Review

It has been found that the world has an 8 × 10 5 km of coastline exceeding a wave power density of 30 kW/m [3]. Also, Indian potential is around 14 kW/m on an average, with about 7500 km of shoreline. Even with just 10% utilization, the energy generated could be anywhere around 3750 × 10 3 to 7500 × 10 3 kW [4].

Types of Hydropower Turbines | Department of Energy

There are two main types of hydropower turbines: reaction and impulse. The type of hydropower turbine selected for a project is based on the height of standing water—referred to as "head"—and the flow, or volume of water over time, at the site. Other deciding factors include how deep the turbine must be set, turbine efficiency, and cost.
