This page lists examples of the power in watts 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.

8 1 milliMilli (symbol m is a SI prefix in the SI system of units denoting a factor of 10-3, or 1/1,000. Adopted in 1795, the prefix comes from the Latin mille meaning one thousand (the plural is milia . See also SI SI prefixes.watt

(10^-3 watts)

5 mW - laser in a CD-ROMThe CD-ROM (an abbreviation for " Compact Disc Read-Only Memory" ( ROM) ) is a non-volatile optical data storage medium using the same physical format as audio compact discs, readable by a computer with a CD-ROM drive. A CD-ROM is a flat, plastic disc wit drive [2]
5-10 mW - laser in a DVD-ROMDVD-ROM is a non-volatile optical data storage medium similar to CD-ROM. Like CD-ROMs, they use a similar technology of microscopic pits on a reflective surface that are read by a laser beam. The difference is that DVD-ROM allows information to be stored drive
100 mW - laser in a CD-R drive
