You predict that $17bn will be saved over 9 years. What makes you think that replacing up to hundreds of millions (you don’t state how many) of industrial motors is going to cost less than $17bn, or even not quite a lot more?

To argue that savings are greater than costs you have to first estimate what the costs are, rather than simply stating that the savings are really big. Maybe the costs are really /really/ big? In fact that seems likely, given that otherwise lots of greedy businesses are apparently shooting themselves in the foot by not replacing their motors voluntarily.

Also, you state that 135 billion kWh is “equal to” 27,000x the installed wind capacity of the UK in 2010. What does that mean? The first is a measure of energy, the second is a measure of power.

Some really interesting data there.

I would think that changes could be made in the commercial arena fairly rapidly. Companies pay more attention to their bottom line than most people pay to their budgets. (That’s a guess.)

The task would seem to be how to get the cost savings info to the ‘decision makers’.

Amazing analysis. I had no idea about the power savings possible with electric motors. Thanks, you have made a convert.

Thanks

The info is all from ABB.

Zach,
I liked your post on the unrealized riches of electric motors efficiency improvements. Great job. How are you calculating your power plant estimates, i.e., your statement “This means that almost every second power plant is producing electricity for the sole purpose of running motors…”
Thanks
