Things to Know About Onshore and Offshore Wind Farms

Laura Davis, Energy CIO Insights | Thursday, January 07, 2021

Wind farms can be built onshore (on land) or offshore (freshwater or sea or), with significant differences between the two.

FREMONT, CA: Ever wondered what principle do offshore and onshore wind farms work? The answer is in the basics of how a wind turbine works. When the wind turns the carbon-fiber blade on the unit, a motor turns, thereby turning kinetic energy into electricity. This energy is transported to the gearbox that converts the spinning blades' slow speed into higher-speed rotary motion—turning the drive shaft swiftly enough to power the electricity generator.

Wind farms can be built onshore (on land) or offshore (freshwater or sea or), with significant differences between the two. Below are some of the advantages of each.

What is offshore wind?

Offshore wind power, also referred to as offshore wind energy, is when wind over open water, usually in the ocean, is used to generate power. Wind farms are built in bodies of water where higher wind speeds are available.

Benefits of Offshore Wind

• Windmills can be constructed that are larger and taller than their onshore counterparts, permitting more energy collection.

• They tend to be far out at sea, denoting they are much less invasive to neighboring countries, facilitating larger farms to be formed per square mile.

• Typically, out at sea, there is a much higher wind speed and force, letting more energy be generated at a time.

• Wind farms have a comparatively negative impact on the atmosphere. They are not constructed in fishing areas, shipping lanes, or a peaceful environment.

• There are no physical restrictions like buildings or hills that could block the wind flow.

What Is Onshore Wind?

Onshore wind power denotes to turbines that are situated on land and use the wind to produce electricity. They are mostly located in areas where there is low conservation or habitat value.

Benefits of Onshore Wind:

• The cost of onshore wind farms is moderately cheap, enabling mass farms of wind turbines.

• The shorter distance between the windmill and the consumer facilitates less voltage drop off on the cabling.

• Wind turbines are quick to install; compared to a nuclear power station, which can take over 20 years, a windmill can be constructed in months.
