Despite the United States of America offshore wind energy sector is currently ramping up in terms of offshore wind farms projects and investment, installed offshore wind farms are yet scarce in the country (30 MW currently installed). Therefore, it is necessary to analyze the current offshore wind energy resource and the projected future variations since an important development is expected in the next decade for the United States offshore wind energy sector. With this aim, simulations from 12 Regional Climate Models from North America Coordinated Regional Climate Downscalling Experiment were used after proving its reliability by comparing the wind speed from simulations with in-situ data. A decrease of the offshore wind energy resource is projected along the 21st century in the United States, especially in the east coast. The central west coast is the only exception to this decrease trend during the near and mid future. In addition, the offshore wind energy resource was classified following a Delphi approach and considering three factors: wind energy, environmental risk and costs. Under this classification, most of the area under scope in both coasts was classified at least as a 4, which is considered as “good” resource. A higher wind energy resource was found for the west coast, with vast coastal areas categorized as 5 (“excellent”). A slight decrease was projected on the United States east coast, mainly caused by a reduction in the indices related to the mean wind speed and the stability of the resource throughout the year.

尽管美国海上风能行业目前在海上风电场项目和投资方面正在迅速增长，但该国已安装的海上风电场仍很稀缺（目前已安装30兆瓦）。因此，有必要分析当前的海上风能资源和预计的未来变化，因为预计在未来十年内美国海上风能行业将取得重要发展。为此，在将模拟风速与现场数据进行比较以证明其可靠性后，使用了来自北美协调区域气候降尺度实验的12种区域气候模型进行的模拟。预计在21世纪，尤其是在东海岸，美国海上风能资源将减少。在不久的将来和中旬，中西部沿海地区是这一下降趋势的唯一例外。此外，按照德尔菲方法对海上风能资源进行了分类，并考虑了三个因素：风能，环境风险和成本。根据这种分类，两个海岸范围内的大多数区域至少被分类为4，这被认为是“良好”资源。在西海岸发现了更高的风能资源，广阔的沿海地区被归类为5个（“优秀”）。预计美国东海岸会略有下降，这主要是由于与全年平均风速和资源稳定性有关的指数下降。根据Delphi方法对海上风能资源进行了分类，并考虑了三个因素：风能，环境风险和成本。根据这种分类，两个海岸范围内的大多数区域至少被分类为4，这被认为是“良好”资源。在西海岸发现了更高的风能资源，广阔的沿海地区被归类为5个（“优秀”）。预计美国东海岸会略有下降，这主要是由于与全年平均风速和资源稳定性有关的指数下降。根据Delphi方法对海上风能资源进行了分类，并考虑了三个因素：风能，环境风险和成本。根据这种分类，两个海岸范围内的大多数区域至少被分类为4，这被认为是“良好”资源。在西海岸发现了更高的风能资源，广阔的沿海地区被归类为5个（“优秀”）。预计美国东海岸会略有下降，这主要是由于与全年平均风速和资源稳定性有关的指数下降。西海岸发现了更高的风能资源，广阔的沿海地区被归类为5个（“优秀”）。预计美国东海岸会略有下降，这主要是由于与全年平均风速和资源稳定性有关的指数下降。在西海岸发现了更高的风能资源，广阔的沿海地区被归类为5个（“优秀”）。预计美国东海岸会略有下降，这主要是由于与全年平均风速和资源稳定性有关的指数下降。
