Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes NEE's effective income tax rates for the three months ended June 30, 2015 and 2014 were approximately 28% and 37%, respectively. The rates for both periods reflect the benefit of PTCs of approximately $37 million and $49 million, respectively, related to NEER's wind projects, as well as ITCs and deferred income tax benefits associated with grants under the Recovery Act (convertible ITCs) totaling approximately $34 million and $13 million, respectively, related to certain solar and wind projects at NEER, including, in 2015, the effect of a state income tax law change that extends the ITC carryforward period for certain wind projects. NEE's effective income tax rates for the six months ended June 30, 2015 and 2014 were approximately 29% and 33%, respectively. The rates for both periods reflect the benefit of PTCs of approximately $75 million and $98 million, respectively, related to NEER's wind projects, as well as ITCs and deferred income tax benefits associated convertible ITCs totaling approximately $52 million and $33 million, respectively, related to certain solar and wind projects at NEER, including, in 2015, the effect of a state income tax law change that extends the ITC carryforward period for certain wind projects. In addition, the rates for the three and six months ended June 30, 2014 reflect a noncash income tax charge of approximately $45 million associated with structuring Canadian assets in connection with the creation of NEP. NEE recognizes PTCs as wind energy is generated and sold based on a per kWh rate prescribed in applicable federal and state statutes, which may differ significantly from amounts computed, on a quarterly basis, using an overall effective income tax rate anticipated for the full year. NEE uses this method of recognizing PTCs for specific reasons, including that PTCs are an integral part of the financial viability of most wind projects and a fundamental component of such wind projects' results of operations. PTCs, as well as deferred income tax benefits associated with convertible ITCs, can significantly affect NEE's effective income tax rate depending on the amount of pretax income. The amount of PTCs recognized can be significantly affected by wind generation and by the roll off of PTCs after ten years of production (PTC roll off).
