Irena ... bringing out a Global Wind Atlas

Irena, DTU launch detailed wind data

The Wind Atlas is the newest addition to the datasets available through Irena’s Global Atlas, a renewable energy mapping tool that uses microscale modelling


The most detailed data and statistics on global wind energy potential are now available online, thanks to a free resource launched today 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. Prior to this release, global wind data was only publically available at 10-kilometre resolution or poorer, which resulted in underestimations, increased risk and increased costs for wind energy planners.

“Wind energy potential across the globe is vast, but the upfront costs of measuring potential and determining the best locations for projects is an obstacle in many countries,” says Irena director-general Adnan Z 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 newest addition to the datasets available through Irena’s Global Atlas, a renewable energy mapping tool. The dataset uses microscale modelling to capture wind speed variability on small scales, allowing for better estimates.

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.

“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,” says Danish Minister for Energy, Utilities and Climate, Lars Christian Lilleholt. “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.”
