Speedwave Energy
A precise tool.
What is the Speedwave Energy & How does it work?
Wave energy is the kinetic and potential energy carried by ocean surface waves. When a wave propagates, its motion can be harnessed to generate electricity, and the amount of usable power depends on the wave’s height and period as well as the physical properties of seawater.
The theoretical power per unit crest length (P) of a regular wave is given by the linear wave‑theory expression:
In practice, engineers use this relationship to estimate the energy that can be extracted by a wave‑energy converter placed along a shoreline or offshore. By inserting realistic values for density, gravity, height, and period, the formula yields the average power available per metre of wave front, guiding device sizing and site selection.
P = frac{rho g^{2} H^{2} T}{64 pi}
P = wave power per unit crest (W·m⁻¹), rho = water density (kg·m⁻³), g = gravitational acceleration (m·s⁻²), H = wave height (m), T = wave period (s)

Frequently Asked Questions
What is wave energy?
Wave energy is the kinetic and potential energy carried by ocean surface waves that can be harnessed to generate electricity.
How does the theoretical power per unit crest length (P) of a regular wave depend?
The theoretical power per unit crest length depends on water density, gravitational acceleration, wave height, and wave period.
What is the formula for calculating wave energy power?
The formula is P = (rho * g^2 * H^2 * T) / (64 * pi), where P is wave power per unit crest, rho is water density, g is gravitational acceleration, H is wave height, and T is wave period.
What factors affect the amount of usable power from ocean waves?
The amount of usable power depends on the wave's height, period, and physical properties of seawater.
How can wave energy be used to generate electricity?
Wave motion can be harnessed to generate electricity by converting its kinetic energy into mechanical energy, which is then converted into electrical energy.
