Most European countries are now investing into wind energy. Only very few of them may be considered as “old” players in the field. Among those which used wind power already back in 1990 were Spain, Denmark, the Netherlands, Belgium and Sweden.
Unfortunately, the data quality of some countries in the beginning stages was rather low so that we confine ourselves to comparing the average output in MWh/MW installed over the period 2000-2010. Taking this as a reference we get the following ranking among those countries which have a relatively long tradition of using wind energy:
Netherlands 2273 MWh/MW (low: 2077 high: 2473)
Spain 2233 MWh/MW (low: 1921 high: 2621)
Sweden 2080 MWh/MW (low: 1784 high: 2625)
Denmark 2028 MWh/MW (low: 1760 high: 2293)
Belgium 1929 MWh/MW (low: 1022 high: 2750)
Germany 1586 MWh/MW (low: 1392 high: 1785)
As indicated these are average values over the first decade of the 21st century. Needless to say that these mean values are rather virtual figures since in reality the availability of the driving force behind the facilities, i.e. the wind, is rather varying by nature. By the way, these figures have been calculated using our specific model which enables us to smooth out distortions due to capacity changes during each year.
The graphics below shows the evolution of wind power in those countries since 1990. The missing data points for some countries refer to the fact that the quality of those data does not fulfil our standards. Thus, we omitted them rather than doing guesswork.
It is quite remarkable that the mean performance between different countries can vary a lot. The most striking feature, however, is that Germany is seriously underperforming when compared to the leading producers in Europe. This may well indicate that selecting the location of a wind farm may not always have been the best choice. Other countries have apparently done a better job.
