Wind energy is harnessed using wind turbines that convert the kinetic energy of the wind into electricity. Wave energy is captured using devices such as wave energy converters, which extract energy from the motion of ocean waves to generate electricity. Both wind and wave energy are renewable sources of energy that can help reduce dependence on fossil fuels.

Wind turbines use the kinetic energy of wind to generate electricity, while wave turbines harness the energy from ocean waves to produce power. Wind turbines are typically installed on land or offshore in areas with strong winds, while wave turbines are situated in the ocean to capture the motion of waves. Both technologies are considered renewable sources of energy, but wave turbines are less common and still in the early stages of development compared to wind turbines.
Wind energy is primarily utilized in wind farms located in open areas with consistent wind patterns, such as plains, coastlines, or offshore locations. These locations allow for large wind turbines to be set up to capture the wind's energy efficiently. Additionally, smaller wind turbines can also be used in residential or commercial settings to harness energy for local use.
The energy of a wave typically comes from a disturbance or vibration that creates the wave motion. This disturbance can originate from various sources, such as wind, earthquakes, or a moving object. Once the wave is created, it carries this energy as it propagates through a medium.
Three things that affect the size and energy of a wave are the wind speed, the duration of the wind blowing, and the fetch (the distance over which the wind blows uninterrupted). These factors determine the amount of energy that can be transferred to the water, resulting in different wave heights and strengths.
A wave can get larger due to factors such as increased wind speed, longer duration of wind blowing over a consistent area, or interference from other waves causing wave energy to combine and amplify. This leads to taller wave heights and increased wave energy.
