Desalination
🚰 Energy consumption for desalinating water has decreased by 85 percent
Energy consumption for desalination has decreased from 20 kWh per cubic meter in the 1970s to 2.5-3.5 kWh today. Producing enough drinking water for one person - about 3 liters per day - through desalination would cost only $2.30 for an entire year.
