Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes NEE's effective income tax rates for the three months ended March 31, 2017 and 2016 were approximately 30% and 27%, respectively. The 2016 effective tax rate was retrospectively adjusted as discussed in Note 7 - Stock-Based Compensation. The rates for both periods reflect the benefit of PTCs of approximately $28 million and $42 million, respectively, related to NEER's wind projects, as well as ITCs and deferred income taxes associated with grants under the Recovery Act (convertible ITCs) totaling approximately $128 million and $37 million, respectively, related to solar and certain wind projects at NEER. 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 ITCs and deferred income taxes 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).
