Wind power is the most reliable, affordable, and abundant source of energy. It was also the first renewable energy source to be utilized for the creation of electricity. It allowed for the transformation of kinetic energy into electricity. In fact, wind power has been used since ancient times. Holland, Sweden, Germany, Denmark, and the UK were the initial pioneers of the sector. However, the US has taken the lead and produces billions of watts of wind power every year. As wind power continues to gain traction, it is important that you understand the difference between onshore and offshore wind power. This post aims to provide you with all the information you need. So, what are you waiting for? Let’s dive in.
- Navigation
A similar mechanical principle is followed by both offshore and onshore wind turbines. They contain rotor blades that spin around a horizontal hub that consists of a generator and a gearbox. As wind moves the turbine, kinetic energy gets passed into the gearbox which is located inside the turbine. The gearbox intensifies the kinetic rotation to power the generator that converts the kinetic energy. Then, the electricity gets delivered to the grid from the turbine.
Even though both types of wind power share the same mechanic principles and materials, they have their fair share of differences. Location is one of their biggest differences. The differences between land and sea are apparent in the construction.
- Cost
Installing onshore wind farms costs less in comparison to offshore farms for obvious reasons. In order to install an offshore wind farm, a platform, interconnection, underwater cables, and other factors are required. Moreover, maintenance of offshore farms involves the use of ocean-faring vessels and helicopters which requires more investment unlike land-based farms that tend to be cheaper to look after,
- Energy Production
A major difference between onshore and offshore farms is that energy production tends to be less predictable and reliable when it comes to onshore wind power. On the other hand, offshore farms provide an adequate supply of energy. Moreover, onshore farms require one to study the wind currents and the terrain before the installation. As housing costs rise, it has become difficult to find or purchase land to house onshore farms. Thus, offshore farms receive a consistent supply of wind and ensure efficient power generation.
- Space
As mentioned above, land is required for onshore wind farms. Since acquiring land can be expensive, onshore wind farms might not always be the most cost-effective option. Moreover, onshore wind turbines have to be placed at a distance of 150m away from obstructions. Land is available for a premium which makes it onshore wind farms not the best option. However, lower installation and maintenance costs make up for it.
Conclusion
There is no denying that onshore wind power is cost-effective. However, it does not mean that offshore wind power is not the right option. At the end of the day, it all comes down to preferences. You can read this renewable energy startup list to learn about the startups bringing about a change.
