[edit] Megawatt (106 watt)

The productive capacity of electrical generators operated by utility companies is often measured in MW. Few things can sustain the transfer or consumption of energy on this scale; some of these events or entities include: lightning strikes, naval craft (such as aircraft carriers and submarines), engineering hardware, and some scientific research equipment (such as the supercollider and large lasers).

For reference, about 10,000 100-watt lightbulbs or 5,000 computer systems would be needed to draw 1 megawatt. Also, 1 MW equals approximately 1341 horsepower. Modern high-powered diesel-electric railroad locomotives typically have a peak power output of 3–5 MW, whereas a typical modern nuclear power plant produces on the order of 500–2000 MW peak output.

[edit] Gigawatt (109 watt)

[edit] Terawatt (1012 watt)

  • 1.7 TW - Geo: average electrical power consumption of the world in 2001
  • 3.327 TW - Geo: average total (gas, electricity, etc) power consumption of the U.S. in 2001
  • 13.5 TW - Geo: average total power consumption of the human world in 2001
  • 44 TW - Geo: average total heat flux from earth's interior (See figure in http://physicsweb.org/articles/news/9/7/16/1)
  • 75 TW - Eco: based on global net primary production (= biomass production) via photosynthesis
  • 50 to 200 TW - Weather: rate of heat energy release by a hurricane
  • In "Star Trek: The Next Generation", the warp core of the fictitious Enterprise-D was able to produce a maximum power output into the Terawatt range.
