Get new shower heads
As technology advances, newer appliances are made with thought toward energetic efficiency. A 30-year-old food processor will likely use more electricity than a brand-new one. That’s why you could save a pretty penny just by buying new machines. Well, the same thing happens with showerheads.
Newer, low-flow models reduce around 30% of the water you use and the amount of energy. That’s because the less hot water you use up, the less work the electric heater has to do to warm it.
