# Is 1.21 Gigawatts A Lot?

## What can produce 1.21 gigawatts?

1 1/2 Nuclear reactors at 800 MW each would generate this much power.

Around 600 Wind turbines at 2 MW each would generate this much power.

1 Lighting strike would generate this much power.

Power levels of lightning strikes vary greatly but 1.21 gigawatts is within their range..

## How much is a gigawatt hour?

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.

## What’s a Jigawatt?

Oh, and a definition: A gigawatt is a unit of power equal to one billion watts.

## How many homes can 1 GW power?

750 homesPowering Good for a Sustainable Energy Future CAISO says one megawatt can meet the instantaneous demand of at least 750 homes, so in these instances, solar was powering more than 750,000 California homes.

## 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.

## Is lightning hotter than the sun?

Lightning is four times hotter than the sun. … A return stroke of lightning, that is, a bolt shooting up from the ground to a cloud (after a stream of electricity came downward from a cloud) can peak at 50,000 degrees Fahrenheit (F). The surface of the sun is around 11,000 degrees F.

## Is lightning DC or AC?

Lightning is an Impulse current. An AC current is alternating in nature i.e. it’s value moves between high and low continuously. There is a frequency of this high and low movement of the AC current. Whereas a DC current is constant in nature.

## How many gigawatts does the world use?

In 2017, the world’s electricity consumption amounted to approximately 22.3 trillion kilowatt hours. One quadrillion watts is approximately equal to one petawatt. Global consumption of electricity has increased over the last decades from 7,323 terawatt hours in 1980 to 22.3 terawatt hours in 2017.

## 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 can’t you get struck by lightning in a car?

You’re safe in a car because the lightning will travel around the surface of the vehicle and then go to ground. This occurs because the vehicle acts like a Faraday cage. Michael Faraday, a British physicist, discovered that a metal cage would shield objects within the cage when a high potential discharge hit the cage.

## Is a lightning bolt 1.21 gigawatts?

Lightning strikes can contain thousands of gigawatts of power, so it’s easily conceivable that a bolt of lightning could supply us with 1.21 gigawatts of power, but only over the course of about 50 microseconds (one microsecond is one-millionth of a second). Sure, that’s a lot of power but actually not a lot of energy.

## How many volts are in a Watt?

Converting the Wattage Using the power equation of 1 watt = 1 ampere × 1 volt and translating that formula to find volts, you end up with 1 volt = 1 watt ÷ 1 ampere. Divide 1000 watts by 10 amperes and the resultant voltage would equal 100 volts.

## How fast is a lightning bolt?

about 3,700 miles per secondIts can depend on air conditions, but the typical lightning bolt moves at 224,000 mph — or about 3,700 miles per second. However, the light you see from the lightning obviously travels at the speed of light, which is roughly 670 million mph, or 186,000 miles per second.

## Can we create lightning?

It is entirely possible to create static electricity, and even lightning using this method. … An artificial lightning bolt. This lightning is generated using capacitor banks (not rubbing stuff together, the way natural lightning is created) and is feeble by comparison to the real thing.

## How many gigawatts are in a lightning strike?

What about a lightning bolt? Could you get this much energy from lightning? According to Wikipedia, a single bolt of lightning can have about 5 x 109 Joules.

## How many KW is a lightning bolt?

138.89 kWhThe kilowatt hours unit number 138.89 kWh converts to 1 flash strike, one average lightning bolt. It is the EQUAL energy value of 1 average lightning bolt but in the kilowatt hours energy unit alternative.

## 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.

## 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.
