how many watts does a piano keyboard use

 

A piano keyboard uses about 60 watts of power. The two most common ways to reduce this amount of energy are by using a computer’s “sleep mode” or by closing the lid on the keyboard.

The downside to these methods is that it can be difficult to find an appropriate setting for your specific device. For example, if you’re trying to save energy with your computer, there are various settings within Windows and Mac OS X that will optimize your machine for maximum efficiency in order to minimize its consumption.
Another way to save electricity is by closing the lid on a keyboard or laptop while it’s in use so that none of the keys are being pressed when they aren’t needed (even though some keyboards will still work if they are closed). This also helps conserve battery life because less current has to flow through each key as well as allowing them all time to cool down and return back into their normal temperature range before being used again.
