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 Calories per Hour
One calorie per hour (cal/h) equals exactly 0.001163 W - the rate of transferring one thermochemical calorie (4.1868 J) per hour. A resting adult generates ~70-80 W ≈ 60,000-70,000 cal/h of heat. The unit appears in European and Asian HVAC standards for small-appliance heat loads and in laboratory calorimetry reporting metabolic activity of small organisms. Calorimetric enzyme assays also express catalytic heat in cal/h per unit enzyme. 1 cal/h = 0.001163 W.
