Desalination plants take seawater and turn it into freshwater. Many countries are hesitant to use desalination plants because they are extremely costly, but California has previously opened one and they know what needs to be done. Renewable energy might be more expensive than current non-renewable energy sources, but prices are decreasing. Photovoltaic is a technology which could be used to power the desalination plants and in 1970 it was priced at $70/w and is now below $2/w (CGIAR, 2013). The government of California will primarily subsidize the plants, however the U.S and Canada government should loan towards the investment as well. The U.S and Canada should help invest because If the solution is not employed and water availability continues to decrease, the food prices will increase for both U.S and Canada which can cause even larger problems. Since California is on the shore, the plants can take in and let out seawater with ease. With sea levels increasing, there is more than enough seawater currently, but a lack of freshwater. If enough water is provided to farms in California, the economic, social, environmental and political impacts which mentioned previously will diminish. Groundwater digging must come to a halt, before the impacts worsen, and a new source of water is necessary. Countries such as Saudi Arabia have begun investing in renewable energy desalination plants, and these plants …show more content…
It takes the desalination plants two gallons of seawater to make one gallon of freshwater. The issue with this is that when the seawater is poured back out, it now has a much larger quantity of salt. Some marine wildlife and animals will not react well with more salt, which could also be contaminated, and the organisms can be put in danger because of this. Moreover, the plants can engulf parts of the ecosystem in the process, which is another environmental weakness. The final issue with desalination is that If enough precipitation comes to California, there is no reason for the government to pay money to keep the plant running, so they often close down and are considered a misspend of important
