Ireland imports 88% of its energy needs and spent €6 billion on energy imports in 2011. While renewable energy use has increased since 1990, it still only accounted for 6.4% of energy used in 2011, though Ireland has set a target of 16% renewable energy by 2020. Wind power is expected to be the most significant contributor to renewable energy targets in the coming years, with the potential to generate €15 billion for Ireland's economy by 2050. Energy efficiency is also a priority, with targets of 20% improved efficiency by 2020 and 33% for the public sector. [/SUMMARY]
