Everything You Need to Know About Wave Energy

Here at James Waste, we are passionate about all things green and renewable. Renewable energy is an evergreen subject and something we love to discuss. A classic example of renewable energy is wave energy.

Wave energy is harnessed from the ocean’s waves and turned into energy. It is a renewable energy because it is unlimited and it does not emit greenhouse gasses that are detrimental to the environment and human health. Ocean waves are one of the most powerful forces known to man and they have been known to reach the height of a 10-storey building! Waves hold a lot of energy within their movement and, thanks to advancements in technology and renewable energy, we are now able to harness that energy to generate electricity.

What is Wave Energy?

Wave energy is a form of renewable energy that can be harnessed from the motion of the waves. Wave energy is energy that is harnessed from the ocean’s waves. The rigorous strength and repetitiveness of the ocean contains a lot of kinetic, or motion, energy that is captured by wave energy technologies to do useful tasks such as generate electricity. However, it is not easy to harness power from wave generator plants and for this reason, there are very few wave generator plants around the world. There are several methods of harnessing wave energy that involve placing electricity generators on the surface of the ocean.

How Does It Work?

As waves roll through the ocean, they create kinetic energy, or movement. This movement can be used to power turbines, which, in turn, create energy that can be converted into electricity and power. There are also several ways of harnessing wave energy that utilise the up and down motion of the waves to power pistons/turn generators. There are many benefits of using wave energy. Read on to find out more.

It’s Highly Predictable

Waves are highly predictable. If the earth keeps turning, the waves keep rolling. The ocean just keeps rolling in waves with predictable regularity, no matter the time of day or night. Therefore, wave energy is far more predictable than wind or solar energy. Wind speeds can die down unexpectedly which can affect the generation of electricity, while solar energy depends on the exposure from the sun and can be drastically affected by cloud coverage. Wave energy, in contrast, is regular and reliable.

Waves flow in a predictable motion, unlike the sun or wind which can be converted into electricity but do not occur in predictable patterns. This is important because, if the power is not supplied continuously this can lead to shortages at times when it is needed most.

Renewable Energy

As with most energy sources we write about here at James Waste, wave energy is a renewable energy source. Renewable means it does not run out and it does not need man’s intervention to continue existing. The waves keep rolling in day and night and this aspect makes wave energy a reliable and efficient source of renewable energy. Wave energy is also a completely green source of energy, it does not emit dangerous greenhouse gasses into the atmosphere and it does not pollute our oceans.

Creation of Green Jobs

Wave energy has other benefits, too. Aside from its renewable production of energy, it also produces many jobs for the unemployed. Communities based in remote areas or working in declining industries often worry about unemployment or lack of job opportunities. The wave energy sector has the potential to create numerous jobs to remote and urban areas alike, opening new opportunities for employment.

Land Remains Undamaged

The remarkable thing about renewable energy sources are that they do not damage the land. Wave energy plants can be situated completely offshore, illuminating any possible risk to land such as soil pollution. Some of the environmental impacts of wave energy may be beneficial, while other could be potentially harmful. However, because wave energy generation is often located far out at sea, the possible environmental effects of wave energy generation are severely reduced.

High Energy Potential

The amount of power that comes from wave energy is enormous. Wave energy contains roughly 1000 times the kinetic energy of wind, allowing smaller devices to produce copious amounts of power. Also, because water is around 850 times as dense as air is, it results in a much higher production of waves averaged over time.


Wave energy is a remarkable source of renewable energy that we hope will take off in the coming years. It has a great amount of potential to become an important source of renewable energy in the future. The ocean has a vast store of power in it, and harnessing this power could provide electricity to everyone on the plant, with plenty left over. It is a clean and environmentally friendly alternative energy source, and it does not cause damage to the earth’s environment.

The current state of our planet and the environment is rapidly declining due to the devastating effects of global warming. And, as a result, it has never been more important for us to source our energy from renewable sources. What are your thoughts on wave energy?
