1. Taking a long shower with less water? Which can!
Do you regularly come out of the shower with shriveled fingers? Chances are you like a nice long and hot shower. Unfortunately, you see that reflected in your energy bill. So consider a water-saving shower head, which uses on average 20 percent less water and energy than a normal shower head. Marlon Mintjes, who works at Milieu Centraal: “If you replace your rain shower with such a water-saving shower head, you can even save 60 percent.”
