Wind energy is the kinetic energy generated by the movement of large amounts of air on the earth's surface. Due to the different temperature changes in various places on the ground after being irradiated by the sun and the different content of water vapor in the air, windmills on the Swedish island of Åland cause differences in air pressure in different places. In the horizontal direction, high-pressure air flows to low-pressure areas, which is the formation of wind. Wind energy resources are determined by wind energy density and the annual accumulated hours of available wind energy. Wind energy density is the power of wind available per unit windward area, and is directly proportional to the cube of wind speed and air density.
There are abundant wind energy resources and vast flat areas at sea, making offshore wind power generation technology a hot spot in recent research and application. The commercial operation of multi-megawatt wind turbines in offshore wind farms is a new trend in wind energy utilization at home and abroad. With the development of wind power generation, the total number of wind turbines on land has become saturated, and offshore wind farms will become the focus of future development. Offshore power generation is a new area of development in the international wind power industry in recent years and is the “direction within the direction”. China's offshore wind energy resource reserves are much larger than those on land. The available wind energy resources at a height of 10 meters exceed 700 million kW, and they are very close to the power load center. At present, Shanghai has begun the construction of offshore wind power projects. By 2010, Shanghai's total installed wind power capacity will reach 200-300 megawatts. To achieve this goal, mainland China's first offshore wind farm will be built on both sides of the Donghai Bridge, China's first long-distance cross-sea bridge.
Offshore wind power generation will be vigorously developed in the next 30 years. China plans to build large-scale offshore wind power stations about 30 miles from the coast. These power stations may be built on huge floating bodies. Possibly 120 feet underwater and built on the continental shelf. Since the wind force on the sea is usually stronger than on the ground, offshore wind power generation has more development prospects. In the next 20 years, offshore wind power generation will reach 75 billion watts, accounting for almost 70% of the installed capacity of all power stations in China.
