    en.wikipedia.org/wiki/List_of_U.S._states_by...

    This is a list of U.S. states by electricity production. The US generated 4,231 TWh in 2022. Some 41 TWh of net imports and 204 TWh of line losses resulted in total consumption of 4,067 TWh. [1] Texas produced the most with 526 TWh, twice as much as Florida or Pennsylvania.

  3. Power electronics - Wikipedia

    en.wikipedia.org/wiki/Power_electronics

    Power electronics is the application of electronics to the control and conversion of electric power. The first high-power electronic devices were made using mercury-arc valves . In modern systems, the conversion is performed with semiconductor switching devices such as diodes , thyristors , and power transistors such as the power MOSFET and IGBT .

    In 1996, there were 3,195 electric utilities in the United States and 65 power marketers. Of these, 2,020 were publicly owned (including 10 Federal utilities), 932 were rural electric cooperatives, and 243 were investor-owned utilities. Fewer than 1,000 utilities are engaged in power generation. [42

    en.wikipedia.org/wiki/Outline_of_electrical...

    Electrical engineering – field of engineering that generally deals with the study and application of electricity, electronics and electromagnetism. The field first became an identifiable occupation in the late nineteenth century after commercialization of the electric telegraph and electrical power supply.

  8. Power engineering - Wikipedia

    en.wikipedia.org/wiki/Power_engineering

    High voltage direct current systems are one of the elements of an electric power grid. Electric power distribution engineering covers those elements of a power system from a substation to the end customer. Power system protection is the study of the ways an electrical power system can fail, and the methods to detect and mitigate for such failures.

  9. Eastern Interconnection - Wikipedia

    en.wikipedia.org/wiki/Eastern_Interconnection

    All of the electric utilities in the Eastern Interconnection are electrically tied together during normal system conditions and operate at a synchronized frequency at an average of 60 Hz. The Eastern Interconnection reaches from Central Canada eastward to the Atlantic coast (excluding Quebec ), south to Florida , and back to the western Great ...
