Without water there is no life. Clean water is scarce on planet earth. One billion people lack access to drinking water while at the same time, immense amounts of water are consumed by agriculture and industry. Water is becoming increasingly important in electricity production. 56% of electricity production comes from hydropower, the most important domestic source of renewable energy.
