Predicting which markets are poised for wind power take-off is a tricky business. As we report elsewhere on these pages, there are many factors that can prevent potential from being fulfilled. Five years ago, for instance, hopes were high for rapid growth across eastern Europe, but with a few exceptions - Romania serving as the best example - those hopes remain a long way from being realised.
We have chosen ten countries, all currently with less than 1GW of installed capacity, that are showing good prospects for growth over the next few years. At the end of 2010 their combined capacity was just 1,088MW and three of them had yet to put a single turbine in the ground. Now, together they account for 5,215MW, a five-fold increase in fewer than five years, and they are all generators of electricity through wind power.
And by the end of 2020? Well, that will depend on many things, but it is conceivable they will collectively grow five-fold once more to reach 25GW, and at least some of them will make the transition from emerging to emergent market status.
