# Quick Answer: How Much Is A Gigawatt Hour?

## Is 1.21 gigawatts a lot?

Sure, that’s a lot of power but actually not a lot of energy.

1.21 gigawatts delivered in 50 microseconds is only about 60,500 Joules, or 14 kilocalories of energy.

Which is the amount of energy in…a cucumber.

But hey—if it works, it works..

## Is a Jigawatt a real thing?

Fictional measurement? The film’s writers Robert Zemeckis and Bob Gale intended for the power to be gigawatts, but heard it pronounced as “jigawatt” and as such spelt and said it that way in the script, not learning the real pronounciation until after the film had been shot. This is not quite true.

## What is a flux capacitor?

What does flux capacitor mean? A flux capacitor refers to a fictional a piece of technology that allows time travel in the popular science-fiction film series Back to the Future.

## How many gigawatts would it take to power a city?

Megawatts are used to measure the output of a power plant or the amount of electricity required by an entire city. One megawatt (MW) = 1,000 kilowatts = 1,000,000 watts. For example, a typical coal plant is about 600 MW in size. Gigawatts measure the capacity of large power plants or of many plants.

## How many watts is a lightning bolt?

10,000,000,000 wattsA lightning bolt contains about 10,000,000,000 watts (10 GW) of electricity, but it only lasts about 5/1,000 of a second. Extrapolated over kilowatt-hours, that’s not as much energy as you’d think.

## How much power is in a lightning bolt?

An average bolt of lightning, striking from cloud to ground, contains roughly one billion (1,000,000,000) joules of energy. This is no small amount, enough to power a 60-watt lightbulb for six months plus a forgotten open door refrigerator for a day.

## Can plutonium generate 1.21 gigawatts?

The chemical element was used in the first version of the DeLorean time machine to create the nuclear energy needed (1.21 gigawatts) to create temporal displacement. One pellet of plutonium covered one trip.

## Why does Doc Brown say gigawatt?

We all know what Doc Brown said in the first movie. “I need a nuclear reaction to generate the 1.21 gigawatts of electricity I need”. But he pronounced gigawatts as if it were spelled with a “j”, as in jigawatts (or jigowatts). … UPDATE Merriam-Webster has pulled their alternate pronunciation for gigawatt.

## What is a gigawatt hour?

Jump to: navigation , search. Gigawatt hours, abbreviated as GWh, is a unit of energy representing one billion (1 000 000 000) watt hours and is equivalent to one million kilowatt hours. Gigawatt hours are often used as a measure of the output of large electricity power stations.

## How many houses can 1 gigawatt power?

300,000 homesMuckerman: If you’re looking at — 1 gigawatt could realistically power 300,000 homes.

## Can a small wind turbine power a house?

Sizing Small Wind Turbines A 1.5-kilowatt wind turbine will meet the needs of a home requiring 300 kilowatt-hours per month in a location with a 14 mile-per-hour (6.26 meters-per-second) annual average wind speed. To help you determine what size turbine you’ll need, first establish an energy budget.

## How much power is a terawatt?

one trillionThe terawatt (TW) is equal to one trillion (1012) watts. The total power used by humans worldwide is commonly measured in terawatts.

## Why are there 1.21 gigawatts?

A gigawatt is equal to one billion watts, and most of us are familiar with a watt. The light bulbs in our homes are typically between 60 and 100 watts. So 1.21 gigawatts would power more than 10 million light bulbs or one fictional flux capacitor in a time-traveling DeLorean.

## How many watts does a house need?

This gives you the amount of energy your panels need to produce every hour. So the average U.S. home (900 kWh/month) in an area that gets five peak sunlight hours per day would need 6,250 watts.
