Have you ever thought about these hand hot air driers and the energy they use?
We need to think that not everything that says it is environmental friendly actually is.
Have you thought on the resources used for having the electricity for powering up the hand drier, what about the higyine? Eficiency and time consumed, even a few extra seconds are enough for not using them... or worse for not washing your hands.
What about the materials used? Same thing happens as stated in the "green energy" products...
We as consumers have the responsibility and have to do a due diligence to make sure that what we buy that is stated as green... actually is responsable with the environment.
