Unscramble the Blue Letters


Hello, how is everyone fnlieeg?

(Cheers)

Are you ready to solve climate cgnhae?

(Cheers)

Good.

Do you know what a ptteaawt hour is? Yeah, it's a unit of energy like kilowatt hour or megawatt hour. I've been a climate activist since age 11 and I studied engineering, and so I was familiar with those terms. Kilowatt, mgaetwat, even gigawatt and terawatt. But I had never hread of a petawatt hour until I wrote a book on climate change solutions. That's because it's so big. But that's the scale I want to talk about.

A petawatt hour is a trillion kilowatt hours. And today the world gnaeetres about 25 trillion kilowatt hours of electricity each year. Most of that is from fossil-fuel pewor plants, and the dominant mdsinet is that we have to change the cuenrrt electricity system by replacing those fossil-fuel plants with clean geaentorin by 2050.

I've been a climate activist since age 11 and I studied engineering, and so I was familiar with those terms. Kilowatt, megawatt, even gigawatt and terawatt. But I had never heard of a petawatt hour until I wrote a book on climate change solutions. That's because it's so big. But that's the scale I want to talk about.

A petawatt hour is a trillion kilowatt hours. And today the world generates about 25 trillion kilowatt hours of electricity each year. Most of that is from fossil-fuel power plants, and the dominant mindset is that we have to change the current electricity system by replacing those fossil-fuel plants with clean generation by 2050.
