While 75% of our planet is covered with water,only about 2% is fresh water—that comes from rivers,lakes,ice and snow.The rest,98% of the water,is in seas and oceans.It is too salty to drink.Then desalination businesses come in.More than 19,000 factories have been built around the world,mostly in coastal countries.They process more than 92 million tons of water every day.But the technology they use requires a lot of energy.
