Some numbers:

June 8, 2010 Water and its Energy - Presentation by Prof. S.A. Kinnas 6

A household in the US requires an average electrical power of 1-2 kW (kiloWatts)

A power plant that produces 1 MW (MegaWatt) = 1,000 kW can supply about 500-1,000 households

A power plant that produces 1 GW (GigaWatt) = 1,000MW = 1,000,000 kW can supply about 500,000 -1,000,000 households
