The wind on almost the entire island blows as evenly and strongly as it does, at best, on the coasts of Central Europe. 3,500 full capacity hours are not a rarity, even for inland Irish wind farms.
But the limited grid capacities hamper a faster expansion of wind energy. With 60 inhabitants per square kilometre, the island is thinly populated – in Germany, for example, almost four times as many people (230 inhabitants per square kilometre) are bustling about in the same space and even more in the United Kingdom. Thus, the infrastructure is rather poor in some areas. As a result, the connection of a new wind farm to the Irish grid takes years in some regions.
