Global Wind Atlas Offers Comprehensive Data

A new free resource has been launched that provides detailed data and statistics on global wind energy potential. Provided by the International Renewable Energy Agency (IRENA) and the Technical University of Denmark (DTU), the Global Wind Atlas, provides wind resource data at one-kilometre resolution; whereas, in the past the best data was at 10-kilometres.

Amin. “The new Global Wind Atlas provides this needed data directly and for free, making it a ground-breaking tool to help jumpstart wind energy development worldwide.”

The Wind Atlas is the latest offering as part of the Global Atlas, a renewable energy mapping tool. The organization explains that the dataset uses microscale modeling to capture wind speed variability on small scales, allowing for better estimates. For example, when locating wind farms, developers naturally pick areas with the highest wind speeds. In datasets that provide average wind speeds over large areas, the enhancement of wind speeds due to small scale features such as hills and ridges are not captured, making the resource appear weaker than it actually is. The Wind Atlas can prevent this underestimation, provide visual maps showing wind speeds at three different heights, and also provide tools to generate and export data and statistics such as wind roses and wind speed distributions over a chosen area.

Danish Minister for Energy, Utilities and Climate, Lars Christian Lilleholt, added, “The release of the Global Wind Atlas demonstrates the support of the international community to expand global renewable energy to address global climate change, increase electricity access and stimulate economic development,” said. Denmark, together with South Africa, has already developed the South African Wind Atlas and we have seen the value of the tool in the development of the wind energy sector.”
