Wind farms should be built offshore for the following reasons:
First, offshore wind resources are abundant and the wind intensity is higher than that on land, which can improve the efficiency of power generation;
Second, there is no sea area restriction, so the scale of power generation can be expanded;
Third , offshore construction can reduce the impact on the land environment and will not affect the ecology. on land;
Fourth, first, offshore power generation has low investment cost and can save money; fifth, offshore power generation can bring more employment opportunities and economic income;
