US

Grid & history

The US grid is a federation of three large interconnections (East, West, Texas) built up through the 20th century. The mix is shifting fast: gas dominates, coal is in decline, and wind and solar are now the largest sources of new capacity.

Availability

Very reliable in cities; rural areas and storm-prone regions (Gulf Coast, Florida, California fire season) vary.

Sockets & hotels

Two flat blades (Type A) for ungrounded outlets, grounded Type B in most modern buildings. Older properties may have only Type A.

Energy mix

Renewables22%
Fossil60%
Nuclear18%

Natural gas is the largest source; coal is in steep decline.

Practical tips

  • Most US plugs are unpolarised Type A; modern grounded ones are Type B.
  • Voltage is 120V. European 230V-only heaters and hair dryers do not work here without a converter.
