What is Wave Energy
All over the world, the green initiative is searching for new forms of renewable energy. One such energy type is wave energy. Just like the name implies, power can be generated from the movement of ocean waves, hence the term “wave energy”. Electricity generators are usually positioned on the ocean surface. As the waves move and ebb, the power created is harnessed and directed to where it is needed.
The produced energy is typically utilized for desalination, diverted to power plants or used to run large pumps. The energy produced is pure and cheap as it is completely natural and environmentally friendly. The cost of generating wave energy is considerably lower than conventional means. For this reason, the research and development is ongoing.
Some projects have been started that have the equipment on the ocean floor. However, the best source of wave power is on the surface where the stored energy of moving waves is at its highest. The amount of energy produced is dependent on several factors, like height and speed of the waves, how dense the water is at that point and the length of each individual wave.
Wave energy is not to be confused with tidal energy. Wave-energy depends on the movement of surface waves while tidal energy is dependent on the movement of the ocean water as a whole during tide changes. The energy produced by tidal energy generators is substantial, yet significantly less than that of wave generators. However, it should be pointed out that wave power is dependent on wave presence, so if there is no wave activity, there is no energy produced. Tidal energy is completely predictable and can be depended on for consistent generation of power.
The costs associated with projects in wave power are fairly low and so the power created is low cost as well. With tidal energy projects, the big blockade is the construction of the device which can take as long as ten years and cost considerably more than wave generators and devices. This will affect the price of that energy to the end user and may be cost prohibitive in some instances.
In short, wave power is not new by any means. The use of water for power production (called hydropower) has been in use for hundreds of years. Renewable energy is our future. Conventional forms of energy are being depleted at a rapid rate. Coal, oil and even wood are eventually going to run out. It will not last forever, so it is time to look seriously at alternative energy sources like wave power. It is clean, environmentally friendly and relatively cheap to produce.

How Efficient Wave Energy
- - In the recent years, studies have shown that ocean waves hold a lot of energy. Wave power can be harnessed, but the cost of the devices that are capable of harnessing this type of energy is quite substantial. The biggest questions are, how efficient is wave power? Can the efficiency of wave power outweigh the cost of building wave power devices?
History of Wave Power
- - Waveenergy has been around since the late 1700’s. Unfortunately, finding alternative sources of energy was not big back then. It is only recently that the there has been an urgent requirement that alternative sources of energy be developed. Let’s take a look at the history of wave energy and how history can pave the way to faster d developments in this field.
Limpet Wave Power Station
- - The world’s first commercial wave-power device is Islay Limpet in the United Kingdom. Electricity generated by the device is connected to UK’s power grid and is sold to thousands of consumers. Here are some details on Islay Limpet and how the device works.
