Wave Energy Pros and Cons
waves as they roll into the shore then back out again. Energy that comes from the
As the technology improves and the demand for renewable energy technologies increases, the costs of investment and construction of wave energy technology are expected to decrease. Oceanic storms such as hurricanes are particularly damaging to wave equipment.
Marine life may be harmed or displaced, or their habitats negatively impacted by the construction of wave energy devices.
Wave energy is as source of power that comes from the endless march of the
Thus far, only a few pilot wave energy projects have been constructed globally. Further research is necessary to determine the the lifespan of the equipment, the associated costs with running the devices, and the impacts of these machines on both human and marine life.
Constantly running wave energy devices can be much noisier than waves are naturally, and this could potentially be disruptive to both humans and sea life living near these devices.
Wave energy has been developing since the s, and yet it is still a nascent technology that needs to be more fully developed.
This slow development is an impediment to investment in this type of renewable energy. Like other forms of hydro power, wave energy does not require the burning of fossil fuels, which can pollute the air, contributing to acid rain and global warming. The energy is entirely clean and endlessly renewable. Wave power has many advantages compared to other forms of renewable energy with its main advantage being that it is predictable.
However, like many other forms of renewable energy, ocean wave energy also has its disadvantages such as its inflexible generation times dependant upon the tides, the visual impact of wave devices on the seas surface, as well as the threat of collision to shipping and navigation. We have seen that there is a wide variety of wave energy conversion devices which can be used to harness the energy captured by a wave power generating system.
Advantages and Disadvantages of Wave Power
Some of the wave energy devices mentioned above are built on the shoreline, making the engineering and construction of these schemes much easier, eliminating the need for long underwater cables runs. But the power density of waves is much less than is available some distance offshore.
However, this can be partly compensated for by the concentration of the wave energy. Offshore devices are situated in much deeper water, with typical depths of more than 30 metres. The wave power available at these deep ocean sites is about three to eight times the wave power available at shoreline sites with a range of completely submerged wave energy conversion devices available for offshore use.
The type of wave energy conversion device used in a particular location, depends on the type of device and its distance from the shoreline.
In the next tutorial about Wave Energywe will look in detail at some of the more common Wave Energy Devices currently being used to generate electricity from the sea. Did you know that Romania has a technical solution with the highest efficiency to capture wave power?.
Your email address will not be published. Due to this, coastal installations and facilities on land has to meet higher restrictions in terms of size and location. We will hopefully in the next following years have more data in this area. Wave power is in very early stages of development, which makes speculating on costs harder. Wave resources, connections to the power grid and the lifespan of the technology are just a few factors that result in different costs for different projects.
Of these factors, the lifespan is the most uncertain one, since this is a relatively new technology and we are lacking data on how long these wave power inventions realistically can operate. At the moment, the costs of wave power are generally very high.
These power plants cannot be developed without sufficient funding from the governments. On the other hand, renewable energy is the future, and the costs are expected to drop when larger facilities are up and running. Many of the parts that are involved in wave power generation require regular maintenance. The fact that some of these parts are under the water does not make it any easier — or cheaper for that matter. The bottom line is that wave power has an enormous global potential.
However, we need more funding and research to polish the technology involved, pushing prices down to a competitive level. Did you know that Romania has a technical solution with the highest efficiency to capture wave power?.
