This page lists examples of the Power in Watt s produced by various different sources of energy. They are grouped by Orders Of Magnitude , and each section covers three orders of magnitude, or a factor of one thousand.
- 2.5 fW - ''Tech:'' minimum discernable signal at the antenna terminal of a good FM radio receiver
- 10 fW (-110 dBm) - ''Tech:'' approximate lower limit of power reception on digital spread-spectrum cell phones
- 1 pW - ''BioMed:'' average power consumption of a human Cell
- 2.5 pW - ''BioMed:'' Sound intensity per square centimeter for average human threshold of hearing at 1000 Hz; 1 Phon or 0 DB SPL
- 150 pW - ''BioMed:'' Power entering a human eye from a 100 watt lamp 1 km away
- 2-15nW - ''Tech:'' Sleep current of some PIC Microcontroller chips such as the PIC12F683. (actual consumption when sleeping depends on voltage supply used, see data sheet, Electrical Characteristics section).
- 5 mW - ''Tech:'' laser in a CD-ROM drive
- 5-10 mW - ''Tech:'' laser in a DVD Player
- 100 mW - ''Tech:'' laser in a CD-R drive
- 5 W - ''Legal:'' maximum power output of a CB or hand-held radio transmitter
- 20-40 W - ''BioMed:'' approximate power consumption of the human brain
- 30-40 W - ''Tech:'' the power of the typical household tube light
- 60 W - ''Tech:'' the power of the typical household Light Bulb
- 82 W - ''Tech:'' peak power consumtion of Pentium 4 CPU
- 100 W - ''BioMed:'' approximate average power used by the Human body
- 120 W - ''Tech:'' power output of 1m2 Solar Panel in full sunlight
- 290 W - ''Units:'' approximately 1000 BTU /hour
- 300-400 W - ''Tech:'' typical PC power supply
- 400 W - ''Tech:'' legal limit of power output of an Amateur Radio station in the United Kingdom
- 500 W - ''BioMed:'' power output of a person working hard physically
- 745.7 W - ''Units:'' 1 Horsepower
- 750 W - ''Astro:'' the amount of sunshine falling on a square metre of the Earth's surface on a clear day
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 Carrier s and Submarine s), engineering hardware, and some scientific research equipment (such as the Supercollider and large Laser s).
For reference, about 10,000 100-watt lightbulbs or 2,000 computer systems would be needed to draw 1 megawatt. Also, 1 MW equals approximately 1341 Horsepower . Modern high-powered Diesel-electric railroad Locomotive s 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.
- 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
- 3.6-7.2 TW - ''Eco:'' global Photosynthetic energy production {Link without Title}
- 13.5 TW - ''Geo:'' average total power consumption of the 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)
- 50 to 200 TW - ''Weather:'' rate of heat energy release by a Hurricane
- 5.3 YW - ''Tech:'' Power produced by the Tsar Bomba fusion bomb, the highest power device ever made by humans
- 386 YW - ''Astro:'' Luminosity of the Sun
