Desalination is a failed technology

Detailed explanation-1: -You may be wondering at this point why desalination isn’t more common, since it would seemingly provide an unlimited supply of potable water. The primary reason is a large energy requirement, which often makes the process expensive.
Detailed explanation-2: -The primary reason we don’t see more desalination plants is due to the cost to operate these plants. Salt dissolves easily in water and it requires a lot of energy to break the chemical bonds.
Detailed explanation-3: -There are environmental costs to desalination as well: in the emissions of greenhouse gases from the large amount of energy used, and in the disposal of the brine, which in addition to being extremely salty is laced with toxic treatment chemicals.
