About Megawatts

A megawatt (MW) is 10⁶ W - the standard unit for utility power plant output. A coal unit produces 300-900 MW; a large nuclear reactor 1,000-1,600 MW. Offshore wind turbines reach 15 MW each (Vestas V236-15.0). The Three Gorges Dam totals 22,500 MW. Aluminium smelters consume 500-600 MW; electric arc furnaces 100-300 MW. Solar farms are rated in MWp; pharmaceutical clean-room HVAC systems in MW. 1 MW = 10⁶ W = 1,341 mechanical hp.

About Milliwatts

A milliwatt (mW) is 10⁻³ W - the power scale of consumer wireless communications. Wi-Fi access points transmit at 100 mW (20 dBm); mobile phones peak at up to 1,000 mW. A laser pointer emits 1-5 mW; an LED indicator 10 mW; Bluetooth Classic peaks at 100 mW. Standby power implications: 1 mW × 10⁹ devices × 1 year = 8,760 MWh - enough to power a small town, underscoring why milliwatt standby matters at scale. 1 mW = 10⁻³ W.
