Though effectiveness and availability for desalination technology has been highly evaluated, why do some people oppose it? There are two objections against desalination technology. First, the process of desalinating seawater uses a lot of fossil fuel energy, so the cost management becomes very expensive, and it also increases greenhouse gas emissions. However, using renewable energy, which can be classified as solar, wind, photovoltaic, biomass, geothermal, and hydropower, has the potential for reducing the energy costs and greenhouse gas emissions compared to fossil fuels. Fossil fuels are the main energy used in modern industrial societies in many countries, but renewable energy has been used as new and sustainable energy in various kinds

Brine is remaining water from desalination plants, and it contains high concentration of salt. Because it is discharged into the ocean directly, the concentration of salt in the seawater becomes higher, yet instead of discharging the brine into the ocean, there is an effective measure for that issue, which is using evaporation ponds. According to Khaled Elsaid1, Nasr Bensalah, and Ahmed Abdel Wahab, in “Inland Desalination: Potentials and Challenges,” the reservoirs that are constructed on the ground in dry and arid places can store brine, so it naturally evaporates, which is the significant role of evaporation ponds. Evaporation ponds are widely used as the appropriate method to dispose of brine from desalination plants. Furthermore, there are some other benefits of evaporation ponds. For example, mechanical equipment is not necessary, so it is easy to construct. It is not expensive to maintain (464). Thus, discharging the brine into the seawater can be avoided by application of evaporation ponds that are harmless to the marine environment because all brine will be evaporated. Moreover, availability of the salt is another advantage of using evaporation ponds. When brine is evaporated, salt will remain due to evaporation, and it is actually useful in many ways. The article “Mission 2012 Clean Water” explains, “The salt could then be used for industrial process such as the manufacture of glass, the production of detergents, polymer production tanning, aerospace alloys, effluent neutralisation, metal refining, sugar extraction and cement manufacture.” To sum up, evaporation is not the only solution to the environmental impact on the marine life due to the inappropriate brine disposal, but the salt that is left by the evaporation ponds to be used in factories and other facilities provides more incentive to use this
