6:30 am – Shower, 5 minutes


WATER is life. Billions of years ago, water sparked the evolution of the first organisms on our planet. Our own body consists of 50 to 60 percent water. Approximately three-quarters of the Earth’s surface is covered by water. However, less than 1 percent of this is available as drinking water. Drinking water is a precious commodity, which we should use sparingly. There are still more than 780 million people around the world without access to clean drinking water.

  • 75 % of the earth’s surface is covered with water, of which
  • 97.5 % is ocean
  • Which leaves 2.5 % as fresh water
  • 70 % of that is ice
  • Which leaves 30 % accessible groundwater
  • Much of that is so polluted that it’s unusable which leaves less than 1 % of the world’s freshwater (or 0.007 % of all water on earth) readily accessible for direct human use


Almost all of us start our morning with a quick shower. For this, we consume on average between 8 to 15 litres of water per minute, depending on the shower head. A five-minute shower therefore uses between 40 to 85 litres of water. In addition, a lot of energy is required to heat the water to a comfortable temperature. No wonder then that water heating accounts for around 12 % of energy bills in German households.

Germans use an average 121 litres of drinking water per person per day - for personal hygiene, laundry, cooking, drinking, etc. Even higher is the proportion of our virtual water consumption – the amount of freshwater “embodied” in a product in the virtual sense. A significant volume of water is used in the production of food, clothing, computers and many other products. According to the Federal Environment Agency this amounts to up to 3,900 litres per person per day.

We can make a difference! Tips for saving water:


  • Take a quick shower instead of running a full bath
  • Install a water-saving shower head and reduce your water consumption by up to 50 %
  • Turn off the water while soaping up or shampooing
  • Repair dripping taps
  • When buying a new washing machine or dishwasher choose an energy- and water-saving model
  • Eat less meat and dairy products as high amounts of water are required for their production
  • Buy high-quality products that last for a long time
  • Do not throw away old clothing or appliances. Instead give away or recycle 
  • Reduce paper consumption
