mix is required. For example diurnal or annual variation of wind resource may becomplimentary to other renewable energy sources.It is expected that geospatial information system (GIS) applications will be one of thesignificant destinations of the Global Wind Atlas datasets. As location of wind resource,and its relationships to population centres, electrical transmission grids, terrain types andprotected land areas, are likely to be important parts of the resource assessmentdownstream of the generation of wind climate statistics.It is not the intention that the result of the Global Wind Atlas will be of interest to windfarm developers, as the accuracy of the resource data and the level of verification willnot satisfy the same standards obtained via dedicated wind resource assessmentperformed for countries individually.Figure 11 show schematically the expected uncertainty for three methodologies todetermine wind resource. The ‘coarse climate data’ curve represents the current sourceof global resource estimation used by global energy planners, i.e. the direct applicationof wind data from global climate models. The ‘site specific study’ curve represents stateof the art resource studies conducted by, among others, commercial companies. Thesetypes of study are necessary for accurate wind resource assessment at a specific sitebefore development of a wind farm project. The ‘global wind atlas’ curve represents themethodology described here, which is designed to optimize appropriateness for globalenergy planners whilst being economical to produce.Figure 11: Schematic graph illustrating the uncertainty of wind resource data as afunction of different scales of aggregation. The horizontal axis gives scale ofaggregation, decreasing from left to right, from global to turbine site scales. The verticalaxis gives uncertainty and a value of 5% is given as reference level of uncertainty. Seemain text for further explanation.Risø International Energy Conference 2011 Proceedings Page 224
6 ConclusionsCurrently, policy makers and energy planners trying to tackling the challenges of climatechange and seeking approaches for climate change mitigation, have no global windresource dataset appropriate for their pressing needs. The Global Wind Atlas, outlined inthis paper, will provide the datasets that are required. While, it will not substitute thededicated country specific wind resource assessment, which feature a more in depthverification process, the level of accuracy will be much superior to the current globaldatasets that are in use.The current practice of global energy modellers is to use coarse resolution reanalysisdatasets. This has the serious shortcoming that the wind energy resource isunderestimated, as small scale variability of wind is missing. This missing variability isresponsible for a large part of the wind energy resource being missed. Furtherinformation about the ‘local’ spatial distribution of wind resources will be gained, thusknowledge of the resources at windy sites can be obtained, rather than mean windresource which smear out the best wind resource values.The Global Wind Atlas will provide data at high resolution for the whole world, using aunified methodology, and will providing an uncertainty estimate based on use of anumber of input reanalysis datasets and methodologies.7 AcknowledgementsThe work was undertaken in collaboration with the Danish Energy Agency.8 ReferencesBadger J., M.
