Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes NEE's effective income tax rates for the three months ended September 30, 2015 and 2014 were approximately 32% and 30%, respectively. The rates for both periods reflect the benefit of PTCs of approximately $29 million and $34 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 $16 million and $37 million, respectively, related to solar and certain wind projects at NEER. NEE's effective income tax rates for the nine months ended September 30, 2015 and 2014 were approximately 30% and 31%, respectively. The rates for both periods reflect the benefit of PTCs of approximately $105 million and $132 million, respectively, related to NEER's wind projects, as well as ITCs and deferred income tax benefits associated with convertible ITCs totaling approximately $67 million and $69 million, respectively, related to solar and certain 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 rate for the nine months ended September 30, 2014 reflects 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).
