Wind Power Generation: Onshore and Offshore

Energy CIO Insights | Friday, February 26, 2021

Wind energy generation requires a certain degree of wind speed, and electricity cannot be produced when the wind is too weak or too strong, for instance, during a typhoon.

FREMONT, CA: Wind power generation uses wind power to produce electricity. There are two types of wind power generation facilities: offshore and onshore. A significant number of offshore wind power plants have already been installed in Japan, and there is anticipation that offshore wind power plants will be built in the future. Many businesses are involved in the constructive growth of onshore and offshore wind power generation ventures.

Offshore and Onshore Wind Power Generation Features

The introduction of wind power plants is progressing worldwide and currently accounts for around half of all electricity produced by renewable energy sources. With the start of the Feed-in-Tariff (FIT) scheme in Japan in 2012, the introduction of offshore wind power plants in Japan has progressed, and with the enactment of the Law to Promoting Utilization of Sea Areas in the Development of Power Generation Facilities Using Maritime Renewable Energy Resources in 2019, more offshore wind power plants are now planned to be constructed in Japan.

Wind energy generation requires a certain degree of wind speed, and electricity cannot be produced when the wind is too weak or too strong, for instance, during a typhoon. However, it is an effective method of producing power that requires both daytime and nighttime power to be produced.

Offshore and Onshore Wind Power Generation

In the generation of wind power, the wind turbine blades' rotational energy is converted into electrical energy. In standard designs, the speed of rotation of the blades is boosted by a gearbox in a nacelle device, which includes the key components and instruments. This rotation powers the turbine generator that produces electricity. The bigger the wind turbine, the higher its power-generating performance, so the construction of larger wind turbines is currently underway in countries worldwide. Wide turbine blades built in recent years and deployed at some onshore locations achieve a maximum height of 130m, while offshore installed turbines exceed 200m.
