Under the original 2009 Renewable Energy Directive Ireland had set a target of producing 16% of all its energy needs from renewable energy sources by 2020 but that has been updated by a second Renewable Energy Directive whose targets are 32% by 2030. Between 2005 and 2014 the percentage of energy from renewable energy sources grew from just 3.1% to 8.6% of total final consumption. By 2020 the overall renewable energy share was 13.5%, short of its Renewable Energy Drive target of 16%.[1] Renewable electricity accounted for 69% of all renewable energy used in 2020, up from two thirds (66.8%) in 2019.[1]
The country has a large and growing installed wind power capacity at 4,405 MW by the end of 2021 producing 31% of all its electricity needs in that year.[2] By February 2024, there was 1GW of solar PV capacity connected to the grid.[3] By April 2024, the grid had 1GW of storage capacity with almost 750MW of that capacity in the form of battery storage[4] the rest supplied by Turlough Hill.
