Wind turbines began cropping up across the landscapes of Spain and Germany in the 1990s. These two countries have the highest wind energy production in the EU. But according to the Global Wind Energy Council, the global installed power capacity in Europe—which is 134,007 MW—has been surpassed by Asia with 141,964 MW, at the end of 2014. The wind power industry is arguably the most mature—and fastest developing—among renewable energies. But, there is still considerable room for improvement to compete with other sources of electricity.
