Joule

The joule (/dʒaʊ,dʒuːljawl, jool; symbol: J) is a derived unit of energy in the International System of Units. It is equal to the energy transferred to (or work done on) an object when a force of one newton acts on that object in the direction of the force's motion through a distance of one metre (1 newton metre or N⋅m). It is also the energy dissipated as heat when an electric current of one ampere passes through a resistance of one ohm for one second. It is named after the English physicist James Prescott Joule (1818–1889). 


Megawatt-Hour

A megawatt-hour (symbol: MW·h) is a unit of energy equal to 3.6 × 10⁹ joules (3.6 gigajoules), representing the energy delivered by one megawatt of power sustained for one hour. It is commonly used in the electricity industry to measure the consumption of large industrial facilities and the output of wind turbines and solar farms. One megawatt-hour equals 1,000 kilowatt-hours.
