Key Terminology
-
Gigawatt-hour [GW*h]
-
A unit of energy representing one gigawatt of power delivered over one hour, equal to 3.6 × 10^12 joules, used primarily for large-scale electrical energy measurements.
-
Megajoule [MJ]
-
An SI derived unit of energy equal to one million joules, used to quantify energy such as work, heat, chemical, and electrical energy in smaller scales.
