75 terawatts of WHAT? Every hour, every day, or the whole year?
As I mentioned on Reddit, Watts are not an over-time based metric. They’re used to measure how much energy is used at any given time. Think of a 60 watt light bulb. That’s not saying how much a light bulb uses over it’s lifetime , or how much it uses in an hour, but how much it uses at any given time.
Watt=Power, so 1 Watt=1 Joule(Energy)/second (Time)
So to answer your question, its terawatts of power. Which is the same as 15 teraJoules/second.
Good infographic – especially with the simplification that it’s all about heating steam. (Be it through nuclear, coal, geothermal or whatever.)
My adds would be (1) solar thermal and geothermal to the heat example on the top (2) a PV explanation at some point and (3) possibly combine hydro generation with your wind generation example. (How electricity is generated through PV is too important to leave off the infographic for sue.) The tidal at the bottom is a bit of a distraction due to the niche technology, but it’s still nice to know.
How about a graph showing the % of electricity generated around the world by they type of generation? Just a thought.
Thanks for posting this here and on reddit!
No problem, thanks for your suggestions!
