Accounting Policies [Abstract]
Derivative Instruments	NEE and FPL use derivative instruments (primarily swaps, options, futures and forwards) to manage the physical and financial risks inherent in the purchase and sale of fuel and electricity, as well as interest rate and foreign currency exchange rate risk associated primarily with outstanding and expected future debt issuances and borrowings, and to optimize the value of NEER's power generation and natural gas and oil production assets. NEE and FPL do not utilize hedge accounting for their cash flow and fair value hedges. With respect to commodities related to NEE's competitive energy business, NEER employs risk management procedures to conduct its activities related to optimizing the value of its power generation and natural gas and oil production assets, providing full energy and capacity requirements services primarily to distribution utilities, and engaging in power and fuel marketing and trading activities to take advantage of expected future favorable price movements and changes in the expected volatility of prices in the energy markets. These risk management activities involve the use of derivative instruments executed within prescribed limits to manage the risk associated with fluctuating commodity prices. Transactions in derivative instruments are executed on recognized exchanges or via the OTC markets, depending on the most favorable credit terms and market execution factors. For NEER's power generation and natural gas and oil production assets, derivative instruments are used to hedge all or a portion of the expected output of these assets. These hedges are designed to reduce the effect of adverse changes in the wholesale forward commodity markets associated with NEER's power generation and natural gas and oil production assets. With regard to full energy and capacity requirements services, NEER is required to vary the quantity of energy and related services based on the load demands of the customers served. For this type of transaction, derivative instruments are used to hedge the anticipated electricity quantities required to serve these customers and reduce the effect of unfavorable changes in the forward energy markets. Additionally, NEER takes positions in energy markets based on differences between actual forward market levels and management's view of fundamental market conditions, including supply/demand imbalances, changes in traditional flows of energy, changes in short- and long-term weather patterns and anticipated regulatory and legislative outcomes. NEER uses derivative instruments to realize value from these market dislocations, subject to strict risk management limits around market, operational and credit exposure. Derivative instruments, when required to be marked to market, are recorded on NEE's and FPL's condensed consolidated balance sheets as either an asset or liability measured at fair value. At FPL, substantially all changes in the derivatives' fair value are deferred as a regulatory asset or liability until the contracts are settled, and, upon settlement, any gains or losses are passed through the fuel clause. For NEE's non-rate regulated operations, predominantly NEER, essentially all changes in the derivatives' fair value for power purchases and sales, fuel sales and trading activities are recognized on a net basis in operating revenues and the equity method investees' related activity is recognized in equity in earnings (losses) of equity method investees in NEE's condensed consolidated statements of income. Settlement gains and losses are included within the line items in the condensed consolidated statements of income to which they relate. Transactions for which physical delivery is deemed not to have occurred are presented on a net basis in the condensed consolidated statements of income. For commodity derivatives, NEE believes that, where offsetting positions exist at the same location for the same time, the transactions are considered to have been netted and therefore physical delivery has been deemed not to have occurred for financial reporting purposes. Settlements related to derivative instruments are substantially all recognized in net cash provided by operating activities in NEE's and FPL's condensed consolidated statements of cash flows. For interest rate and foreign currency derivative instruments, all changes in the derivatives' fair value, as well as the transaction gain or loss on foreign denominated debt, are recognized in interest expense and the equity method investees' related activity is recognized in equity in earnings (losses) of equity method investees in NEE's condensed consolidated statements of income.
Fair Value Measurements	Fair Value Measurements of Derivative Instruments – The fair value of assets and liabilities are determined using either unadjusted quoted prices in active markets (Level 1) or other pricing inputs that are observable (Level 2) whenever that information is available and using unobservable inputs (Level 3) to estimate fair value only when relevant observable inputs are not available. NEE and FPL use different valuation techniques to measure the fair value of assets and liabilities, relying primarily on the market approach of using prices and other market information for identical and/or similar assets and liabilities for those assets and liabilities that are measured at fair value on a recurring basis. NEE's and FPL's assessment of the significance of any particular input to the fair value measurement requires judgment and may affect placement within the fair value hierarchy levels. Non-performance risk, including the consideration of a credit valuation adjustment, is also considered in the determination of fair value for all assets and liabilities measured at fair value. NEE and FPL measure the fair value of commodity contracts using a combination of market and income approaches utilizing prices observed on commodities exchanges and in the non-exchange traded markets, or through the use of industry-standard valuation techniques, such as option modeling or discounted cash flows techniques, incorporating both observable and unobservable valuation inputs. The resulting measurements are the best estimate of fair value as represented by the transfer of the asset or liability through an orderly transaction in the marketplace at the measurement date. Exchange-traded derivative assets and liabilities are valued using observable settlement prices from the exchanges and are classified as Level 1 or Level 2, depending on whether positions are in active or inactive markets. NEE, through its subsidiaries, including FPL, also enters into non-exchange traded commodity derivatives. The majority of the valuation inputs are observable using exchange-quoted prices. NEE, through NEER, also enters into full requirements contracts, which, in most cases, meet the definition of derivatives and are measured at fair value. These contracts typically have one or more inputs that are not observable and are significant to the valuation of the contract. In addition, certain non-exchange traded derivative options at NEE have one or more significant inputs that are not observable, and are valued using industry-standard option models. In all cases where NEE and FPL use significant unobservable inputs for the valuation of a commodity contract, consideration is given to the assumptions that market participants would use in valuing the asset or liability. The primary input to the valuation models for commodity contracts is the forward commodity curve for the respective instruments. Other inputs include, but are not limited to, assumptions about market liquidity, volatility, correlation and contract duration as more fully described below in Significant Unobservable Inputs Used in Recurring Fair Value Measurements. In instances where the reference markets are deemed to be inactive or do not have transactions for a similar contract, the derivative assets and liabilities may be valued using significant other observable inputs and potentially significant unobservable inputs. In such instances, the valuation for these contracts is established using techniques including extrapolation from or interpolation between actively traded contracts, or estimated basis adjustments from liquid trading points. NEE and FPL regularly evaluate and validate the inputs used to determine fair value by a number of methods, consisting of various market price verification procedures, including the use of pricing services and broker quotes to support the market price of the various commodities. Where there are assumptions and models used to generate inputs for valuing derivative assets and liabilities, the review and verification of the assumptions and models are undertaken by individuals in an independent control function. NEE uses interest rate contracts and foreign currency contracts to mitigate and adjust interest rate and foreign currency exchange exposure related primarily to certain outstanding and expected future debt issuances and borrowings when deemed appropriate based on market conditions or when required by financing agreements. NEE estimates the fair value of these derivatives using an income approach based on a discounted cash flows valuation technique utilizing the net amount of estimated future cash inflows and outflows related to the agreements. Cash Equivalents and Restricted Cash Equivalents – NEE and FPL hold investments primarily in money market funds. The fair value of these funds is estimated using a market approach based on current observable market prices. Special Use Funds and Other Investments – NEE and FPL hold primarily debt and equity securities directly, as well as indirectly through commingled funds. Substantially all directly held equity securities are valued at their quoted market prices. For directly held debt securities, multiple prices and price types are obtained from pricing vendors whenever possible, which enables cross-provider validations. A primary price source is identified based on asset type, class or issue of each security. Commingled funds, which are similar to mutual funds, are maintained by banks or investment companies and hold certain investments in accordance with a stated set of objectives. The fair value of commingled funds is primarily derived from the quoted prices in active markets of the underlying securities. Because the fund shares are offered to a limited group of investors, they are not considered to be traded in an active market. Fair Value Measurement Alternative – NEE holds investments in equity securities without readily determinable fair values, which are initially recorded at cost, of approximately $642 million and $665 million at June 30, 2025 and December 31, 2024, respectively, and are included in noncurrent other assets on NEE's condensed consolidated balance sheets. Adjustments to carrying values are recorded as a result of observable price changes in transactions for identical or similar investments of the same issuer.
Restricted Cash	Restricted Cash – At June 30, 2025 and December 31, 2024, NEE had approximately $254 million ($40 million for FPL) and $159 million ($101 million for FPL), respectively, of restricted cash, which, at December 31, 2024, was offset by $244 million of cash received on exchange-traded derivative positions resulting in a balance of $(85) million. Restricted cash accounts are included in current other assets on NEE's and FPL's condensed consolidated balance sheets and primarily relate to debt service payments and margin cash collateral requirements (funding) at NEER and bond proceeds held for construction at FPL. In addition, where offsetting positions exist, restricted cash related to margin cash collateral of $87 million is netted against derivative liabilities at June 30, 2025 and $279 million is netted against derivative assets at December 31, 2024. See Note 2.
Storm	Storm Cost Recovery – In January 2025, FPL began recovering eligible storm costs and replenishment of the storm reserve through a storm surcharge totaling approximately $1.2 billion, related to Hurricanes Debby, Helene and Milton which impacted FPL's service area in 2024. The amount is being collected over a 12-month period and is subject to refund based on an FPSC prudence review. Recoverable storm costs are recorded as current regulatory assets on NEE's and FPL's condensed consolidated balance sheets. The unpaid portion of the storm restoration costs at June 30, 2025 and December 31, 2024, of approximately $137 million and $557 million, respectively, including estimated capital costs, is included in current other liabilities on NEE's and FPL's condensed consolidated balance sheets.
Structured Payables	Structured Payables – At June 30, 2025 and December 31, 2024, NEE's outstanding obligations under its structured payables program were approximately $1.1 billion and $4.0 billion, respectively.
Income Tax	Income Taxes – For taxable years beginning after 2022, clean energy tax credits generated during the taxable year can be transferred to an unrelated purchaser for cash and are accounted for under Accounting Standards Codification 740 – Income Taxes. Proceeds resulting from the sales of clean energy tax credits for the six months ended June 30, 2025 and 2024 of approximately $310 million and $511 million, respectively, are reported in the cash received for income taxes – net within the supplemental disclosures of cash flow information on NEE's condensed consolidated statements of cash flows. In connection with entering into the agreements to sell clean energy tax credits, NEECH provides certain indemnifications to the purchasers regarding the existence and qualifications of such credits. NEE has not recorded any material liability related to these indemnifications after considering the nature of the indemnifications and NEE’s experience in generating and utilizing clean energy tax credits. NEE's exposure to refund credits sold generally terminates based on the individual purchaser’s tax return statute of limitations which cannot be estimated.
Noncontrolling Interests	Noncontrolling Interests – At June 30, 2025 and December 31, 2024, approximately $8,759 million and $9,062 million, respectively, of noncontrolling interests on NEE's condensed consolidated balance sheets relates to differential membership interests. For the three months ended June 30, 2025 and 2024, NEE recorded earnings of approximately $417 million and $357 million, respectively, and for the six months ended June 30, 2025 and 2024 approximately $811 million and $705 million, respectively, associated with differential membership interests, which is reflected as net loss attributable to noncontrolling interests on NEE's condensed consolidated statements of income.
Disposal of Businesses/Assets	Disposal of a Business – In July 2025, a subsidiary of NextEra Energy Resources entered into an agreement to sell a 50% equity interest in a joint venture, consisting of a rate-regulated transmission asset located in California. NEER expects to close the sale in the first quarter of 2026, subject to the satisfaction of customary closing conditions and the receipt of regulatory approvals, for cash proceeds of approximately $270 million, subject to closing adjustments. Upon closing, the transmission assets and liabilities will be removed from NEE's balance sheet and NEE's remaining 50% interest will be reflected as an equity method investment.
