How A lot Energy Is 1 Gigawatt?



A date that almost all film buffs know by coronary heart, October 21, 2015, is the day Marty McFly and Doc Brown journey to the long run in Steven Spielberg’s 1989 traditional Again to the Future Half II.

Though you might not have remembered the date, you’ve in all probability heard of Doc’s DeLorean, which takes 1.21 gigawatts (GW) of energy to journey via time. Admittedly, our nationwide labs haven’t fairly discovered time journey simply but, however they do analyze energy.

As an illustration, on the finish of 2022, there have been over 144 GW of wind energy and 110 GW of photo voltaic photovoltaic (PV) whole in the USA. To assist put this quantity in perspective, it’s vital to know simply how massive 1 GW is. A watt is a measure of energy and there are 1 billion watts in 1 GW. (And should you needed to interrupt it down even additional, 1 million watts = 1 megawatt (MW) and 1,000 watts = 1 kilowatt (kW).)

Want a stronger visible? Listed below are six examples equal to 1 GW of energy:

How A lot Energy Is 1 Gigawatt?

2.469 Million Photovoltaic (PV) Panels

Based mostly on a consultant silicon mannequin panel measurement of 405 watts. (Supply)

310 Utility-Scale Wind Generators

Based mostly on the common utility-scale wind turbine measurement of three.23 MW put in in 2022. (Supply)

100 Million LED Bulbs

Based mostly on typical efficiency, a light-emitting diode (LED) A19 lamp is roughly 92 lumens per watt and consumes about 10 watts. (Supply)

Roughly 1.3 Million Horses

Based mostly on horsepower to watts conversion: 746 watts = 1 horsepower. Picture courtesy of Cynthia Shahan | CleanTechnica.

2,000 Corvette Z06s

Based on the automaker’s web site, the Chevy Corvette Z06 engine delivers 670 horsepower. Two-thousand of these engines would equal 1.34 million horsepower, or 1 GW. (Supply)

9,090 Nissan LEAFs

The Nissan LEAF has a 110 kilowatt (kW) motor. So, 1 million kW divided by 110 kW = the utmost energy of 9,090 Nissan LEAFs. (Supply)

I do not like paywalls. You do not like paywalls. Who likes paywalls? Right here at CleanTechnica, we applied a restricted paywall for some time, however it at all times felt fallacious — and it was at all times powerful to resolve what we should always put behind there. In concept, your most unique and finest content material goes behind a paywall. However then fewer individuals learn it! We simply do not like paywalls, and so we have determined to ditch ours.

Sadly, the media enterprise continues to be a troublesome, cut-throat enterprise with tiny margins. It is a endless Olympic problem to remain above water and even maybe — gasp — develop. So …
