Spain relies on imports for most of its oil consumption domestically and is a major global producer and reference for liquefied petroleum gas. Wind energy has become the third largest source for Spain's power system as the country is now the leading wind power producer in Europe. Hydropower is also a significant clean energy source for Spain, though it can impact landscapes. Solar power facilities like the PS20 and PS10 towers near Seville use large mirrors to produce electricity from the sun.
