Based on proprietary data released to the public, Nevada was named America's "Most Wasteful State" for the years 2005-2010; where each
Per-unit system as base values; power and voltage are typically chosen. All quantities are specified as multiples of selected base values. For example, the base power might be the rated power of a transformer, or perhaps an arbitrarily selected power which makes power quantities in the system more convenient. The base voltage might be the nominal voltage of a bus. Different types of quantities are labeled with the same symbol (pu); it should be clear whether the quantity is a voltage, current, or other unit of measurement. There are several reasons for using a per-unit system: The per-unit system was developed to
