About Kilowatt Hour (kWh)
A kilowatt-hour (kWh) is the energy consumed by a 1,000-watt (1 kW) device operating for one hour — equal to 3,600,000 joules. It is the standard unit on residential and commercial electricity bills worldwide. One kWh is a tangible, human-scale quantity: it runs a 60 W lightbulb for 16.7 hours, powers a modern refrigerator for a day, or adds about 6 km of range to a typical electric vehicle. Global electricity consumption and power plant outputs are expressed in terawatt-hours (TWh).
A typical US household uses about 886 kWh per month. Charging an electric vehicle from empty to full takes 50–100 kWh depending on battery size.
About Tons of TNT (tTNT)
A ton of TNT equals 4,184,000,000 joules (4.184 GJ) and is the standard unit for large conventional bombs, non-nuclear explosives, and the lower end of nuclear weapon yields. The Massive Ordnance Air Blast (MOAB), the largest non-nuclear bomb in the US arsenal, has a yield of about 11 tons of TNT. The Hiroshima atomic bomb released the equivalent of approximately 15,000 tons (15 kilotons) of TNT.
The largest conventional bomb (MOAB) yields about 11 tons of TNT. A V2 rocket warhead carried about 1 ton of TNT.
Kilowatt Hour – Frequently Asked Questions
What is the difference between kW and kWh?
A kilowatt (kW) is a rate of energy use — power. A kilowatt-hour (kWh) is a total amount of energy consumed over time. A 2 kW heater running for 3 hours uses 6 kWh. Your electricity meter tracks cumulative kWh, not kW. Confusing the two is one of the most common mistakes in energy discussions, similar to confusing speed with distance.
How many kWh does the average US household use per month?
The US Energy Information Administration puts the national average at about 886 kWh per month (roughly 29 kWh per day). Homes in hot states like Louisiana average over 1,100 kWh due to air conditioning; mild-climate states like Hawaii average under 500 kWh. A household's bill equals kWh consumed multiplied by the local rate, typically $0.10–$0.30 per kWh.
How many kWh does it take to fully charge an electric car?
Most EVs have battery packs of 50–100 kWh. A Tesla Model 3 Long Range holds about 75 kWh; a Rivian R1T about 135 kWh. Charging from empty to full at home costs roughly $7–$20 depending on battery size and local electricity rates. At $0.15/kWh, a 75 kWh charge costs $11.25 — far cheaper than filling a petrol tank for equivalent range.
How much does one kilowatt-hour of electricity cost?
In the US, residential electricity averages about $0.16/kWh nationally but ranges from $0.10 in Louisiana to $0.45 in Hawaii. In Europe, prices are higher: Germany averages €0.30–0.40/kWh. One kWh runs a modern fridge for about 24 hours, powers a 55-inch LED TV for 10 hours, or charges a smartphone roughly 80 times.
How many kWh does a solar panel produce per day?
A standard 400 W residential solar panel produces about 1.2–2.0 kWh per day depending on location, orientation, and weather. In sunny Arizona, expect the high end; in cloudy Seattle, the low end. A typical US home rooftop system of 20 panels (8 kW) generates roughly 25–40 kWh per day — enough to cover most or all of the household's electricity needs.
Tons of TNT – Frequently Asked Questions
How powerful is one ton of TNT in real terms?
One ton of TNT releases 4.184 GJ — roughly the energy of 120 liters of petrol or the electricity an average US home uses in 1.2 days. In blast terms, one ton of TNT in open air produces lethal overpressure within about 15–20 meters and can shatter windows at 100+ meters. The MOAB bomb (11 tons TNT) flattened structures across a 150-meter radius.
What is the difference between a ton of TNT, a kiloton, and a megaton?
They differ by factors of 1,000: 1 kiloton = 1,000 tons, 1 megaton = 1,000,000 tons. Conventional bombs are rated in tons (the MOAB is 11 tons). Tactical nuclear weapons are rated in kilotons (Hiroshima was ~15 kt). Strategic thermonuclear warheads are rated in megatons (modern US warheads are 0.3–0.475 Mt). The scale spans nine orders of magnitude.
How many tons of TNT was the Beirut port explosion in 2020?
The 2020 Beirut explosion was caused by 2,750 tonnes of ammonium nitrate and was estimated at roughly 500–1,100 tons of TNT equivalent. For comparison, the Oklahoma City bombing (1995) was about 2 tons TNT equivalent, and the Halifax explosion (1917) was roughly 2,900 tons. Beirut ranked among the largest non-nuclear explosions in history.
How is tons of TNT used for meteor and asteroid impact energy?
Small meteor airbursts are rated in tons or kilotons of TNT. The 2013 Chelyabinsk meteor released about 440,000 tons (440 kt) — roughly 30 times the Hiroshima bomb. The Tunguska event (1908) is estimated at 3–15 megatons. The Chicxulub asteroid that ended the dinosaurs released roughly 100 trillion tons (100 million megatons) of TNT equivalent energy.
What is the largest conventional (non-nuclear) explosion in tons of TNT?
The largest planned non-nuclear explosion was the British demolition of Heligoland fortifications in 1947, using 6,700 tons of TNT equivalent. The largest accidental explosion was the Halifax harbour disaster (1917) at roughly 2,900 tons. The largest conventional bomb, the US GBU-43/B MOAB, yields about 11 tons — tiny compared to accidental industrial blasts.
