What is the relationship between wave properties and wave energy?

The energy transported by a wave is directly proportional to the square of the amplitude of the wave. This energy-amplitude relationship is sometimes expressed in the following manner. This means that a doubling of the amplitude of a wave is indicative of a quadrupling of the energy transported by the wave.

How is ocean wave energy converted to electricity?

Ocean waves are converted to electricity with wave energy converter, or WEC, devices. The surface portion moves faster than the submerged part, and the WEC converts that relative motion into electricity.

What is wave energy called?

Wave Energy also known as Ocean Wave Energy, is another type of ocean based renewable energy source that uses the power of the waves to generate electricity. Unlike tidal energy which uses the ebb and flow of the tides, wave energy uses the vertical movement of the surface water that produce tidal waves.

Why is wave energy important?

Wave energy is unique because it is the most concentrated form of renewable energy on earth, with power density much higher than that of wind and solar energy. As waves can travel for hundreds and even thousands of kilometers with virtually no loss of energy, they act as an energy reservoir charged by the wind.

How much power does wave energy produce?

The International Energy Agency estimates that wave power could potentially produce 8,000 to 80,000 TWh yearly; ocean thermal energy could produce 10,000 TWh; osmotic power (from salinity differences) could produce 2,000 TWh and tides and marine currents could produce 1,100 TWh.

How does a wave begin?

Waves are created by energy passing through water, causing it to move in a circular motion. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest.

What does it mean to catch the wave?

to seize an opportunity that is presented to you, especially an opportunity to do something new.

What is the face of a wave?

Shoulder (or “Face”): The part of a wave that has not broken yet. Surfers ride from the area that is breaking, toward the unbroken section of the wave called “shoulder” or “face”. You want to avoid getting caught in this zone when sitting or paddling our to the surf, as this is where the wave has most of its power.

What is an open face wave?

Clean: When the waves have a smooth, glassy surface and break from one point steadily along it’s length providing an open face for a surfer to ride on. Often accompanied by offshore winds. The opposite of messy.

How do you ride closeout waves?

Fall backwards off the board, kicking the board out in front of you. Try to land your body flat, just on the wave side of the trough. The wave will tend to carry your board forward, which is why you kick it out in front, and the part of the wave just up-wave from the trough will give you a bit of a cushion to hit.

What does it mean when a wave breaks?

In fluid dynamics, a breaking wave or breaker is a wave whose amplitude reaches a critical level at which some process can suddenly start to occur that causes large amounts of wave energy to be transformed into turbulent kinetic energy.
