Does electric induction cooking use fewer watts ?

In a off-grid solar system, it's imperative to save as many watts as you can.
But no one has run a test and can say cooking the normal electric way uses X watts and induction saves X watts.
If anyone has found an article that defines how much induction can save, I'd love to know !
PS: I have an induction cooktop next to my electric stove and wonder if it saves electricity ?

If you have an amp meter you can see how many amps it uses when the burner is heating.

What's the label on the induction say?
 
I will give you our findings. There are differences and I'll explain.

In and "old style" element rangetop, there are 2 sizes, 8" and 10"/ 12" elements. The 8" elements pull about 1,200 to 1,500 watts, while the 10" / 12" pulls about 1,800 to 2,200 watts at full power on high.
In a newer style glasstop range (like the one shown in your picture) many burners have different size elements which allow different sizes and wattages, but on full power they are about the same as the old style elements.

Now here's where it gets interesting. Most if not all that I've seen of the portable induction tops are max 1,800 watts on the high setting, but what people don't realize they will use about the same power as a conventional rangetop. Here's where it gets interesting. The old style and newer glasstop cycle the burner on and off to maintain the temperature, but the induction is a bit more steady (does not cycle the burner on and off). The induction cooktop heats much much faster and we've done the test of boiling water and the induction boiled the water in 1/2 the time. On and induction cooktop you will cook much faster but the electrical usage will be about the same. Cook time is the savings here. The burner area on an induction cooktop is also much cooler.

Now to explain how we arrived at our conclusion: When I was building BAB's (aka the Battle Cruiser) we went away from a gas stove and went to induction cooktops (two of them) and conducted all these tests while we were still living in our old house. Induction is far superior and requires pans made for induction, but we see that as a good thing.

Our thoughts? We were so impressed by the induction cooktop we bought a brand new slide in induction range for the barndominium.

Think it cost less than Nat gas to cook?
 
Thanks for the analysis. I've been using induction for about a week.
Bought it a long time ago and had it stored in a bottom cabinet and had forgotten about it. :)
