The threat of water shortages is one of the largest threats facing the world today and to try and spread the word of how severe this crisis could become, Barclays has teamed up with the Columbia Water Centre to “explore how energy companies and public utilities can help alleviate water shortages and improve water quality through new technologies and better practices.” According to the report, only 2.5% of the world’s water is fresh, yet in the US around 90% of water withdrawals are used for public and industrial use and $1 trillion will be needed in water investment in the US alone.
