About Terawatts
A terawatt (TW) is 10¹² W. All of human civilisation consumes ~17-18 TW (electricity + heat + transport combined); global electricity generation alone is ~9 TW. Solar irradiance intercepted by Earth is ~174,000 TW; photosynthesis captures ~130 TW. The National Ignition Facility (NIF) fusion laser produces pulses of ~500 TW lasting nanoseconds. High-power laser facilities for nuclear physics and ICF research routinely exceed 1 TW in ultrashort pulse regimes. 1 TW = 10¹² W.
About Mechanical Horsepower
The mechanical horsepower (hp) is exactly 550 ft·lbf/s ≈ 745.7 W - defined by James Watt by timing mine horses to set a comparable steam engine rating. A typical compact car produces 100-150 hp (75-112 kW); a sports car 300-600 hp; an F1 car ~1,000 hp (745 kW). SAE net horsepower is measured at the flywheel with all accessories fitted. Marine diesel engines, aircraft piston engines, and lawn equipment are still rated in hp. 1 hp = 550 ft·lbf/s = 745.6998715822704 W.
