  2. Cost of electricity by source - Wikipedia

    en.wikipedia.org/wiki/Cost_of_electricity_by_source

    The levelized cost of electricity (LCOE) is a metric that attempts to compare the costs of different methods of electricity generation consistently. Though LCOE is often presented as the minimum constant price at which electricity must be sold to break even over the lifetime of the project, such a cost analysis requires assumptions about the value of various non-financial costs (environmental ...

  3. Electricity generation - Wikipedia

    en.wikipedia.org/wiki/Electricity_generation

    Electricity generation is the process of generating electric power from sources of primary energy. For utilities in the electric power industry , it is the stage prior to its delivery ( transmission , distribution , etc.) to end users or its storage , using for example, the pumped-storage method.

  4. Unit commitment problem in electrical power production

    en.wikipedia.org/wiki/Unit_Commitment_Problem_in...

    generation is distributed across a vast geographical area (e.g., a country), and therefore the response of the electrical grid, itself a highly complex system, has to be taken into account: even if the production levels of all units are known, checking whether the load can be sustained and what the losses are requires highly complex power flow ...

  5. Load factor (electrical) - Wikipedia

    en.wikipedia.org/wiki/Load_factor_(electrical)

    In electrical engineering the load factor is defined as the average load divided by the peak load in a specified time period. [1] It is a measure of the utilization rate, or efficiency of electrical energy usage; a high load factor indicates that load is using the electric system more efficiently, whereas consumers or generators that underutilize the electric distribution will have a low load ...

  6. Load duration curve - Wikipedia

    en.wikipedia.org/wiki/Load_duration_curve

    A load duration curve (LDC) is used in electric power generation to illustrate the relationship between generating capacity requirements and capacity utilization. A LDC is similar to a load curve but the demand data is ordered in descending order of magnitude, rather than chronologically. The LDC curve shows the capacity utilization ...

  7. Wind power - Wikipedia

    en.wikipedia.org/wiki/Wind_power

    Small-scale wind power is the name given to wind generation systems with the capacity to produce up to 50 kW of electrical power. [104] Isolated communities, that may otherwise rely on diesel generators, may use wind turbines as an alternative.

  8. Energy economics - Wikipedia

    en.wikipedia.org/wiki/Energy_economics

    Energy economics is a broad scientific subject area which includes topics related to supply and use of energy in societies. [1] Considering the cost of energy services and associated value gives economic meaning to the efficiency at which energy can be produced. [ 2 ]

  9. World energy supply and consumption - Wikipedia

    en.wikipedia.org/wiki/World_energy_supply_and...

    It is used as fuel gas, also in thermal power stations. Nuclear reaction heat is used in thermal power stations. Biomass is used directly or converted to biofuel. Electricity generators are driven by steam or gas turbines in a thermal plant, or water turbines in a hydropower station, or wind turbines, usually in a wind farm.
