Wind power is a source of energy that is both affordable and renewable. However, decision-makers have been reluctant to invest in wind energy due to a perception that wind farms require a lot of land compared to electric power plants driven by fossil fuels. Research was based on the assessment of the land-use of close to 320 wind farms in the U.S.

paints a very different picture.However, decision-makers have been reluctant to invest in wind energy due to a perception that wind farms require a lot of land compared to electric power plants driven by fossil fuels. Research led by McGill University and based on the assessment of the land-use of close to 320 wind farms in the U.S. paints a very different picture.

The research also shows that if wind turbines are sited in areas with existing roads and infrastructure, such as on agricultural land, they can be approximately seven times more efficient, in terms of energy produced per square metre of land directly impacted by the infrastructure, than projects that are developed from scratch.

By combining information gathered through GIS with machine learning models developed using nearly 2000 images of wind farms from the American portion of the Western Interconnection , the researchers were able to train a deep learning model to analyze land use in wind farms. By doing so, they were able to assess a range of factors that contribute to the land directly impacted by wind infrastructure.
