  • California is in the 4th year of a severe drought, but it's right next to the biggest

  • ocean on the planet.

  • Some of our viewers want to know, why aren't they just using that?

  • Hey everyone, Julian here for DNews.

  • California is thirsty.

  • On top of having almost 39 million residents, California grows an unbelievable amount of

  • food.

  • With agriculture being a 36 billion dollar industry in the state, it's more than twice

  • as big as any other states.

  • And that means that in 2010 the US Geological Survey estimates California used almost, I

  • hope you're sitting down for this number, 52 trillion liters of water.

  • That's 142 billion liters a day.

  • But California hasn't been getting the precipitation it needs for the past 4 years and now they're

  • scrambling for new sources of drinking water.

  • Los Angeles county is offering to buy water from Sacramento valley farmers.

  • The state is urging people to conserve water and was threatening to fine people during

  • the ice bucket challenge.

  • But, hello, guys.

  • the pacific ocean is right there.

  • Saltwater minus salt equals water, let's go, do I have to think of everything?

  • Actually San Diego county had the same idea, they're currently building the biggest desalination

  • plant in the western hemisphere to the tune of 1 billion dollars.

  • When it's finished next year it will make 204 million liters of potable water daily

  • and sell at a dollar for every 616 liters.

  • Wow, we're in the clear.

  • Eh, not so fast.

  • While it sounds like a lot of cheap water, the opposite is true.

  • That price is 80% higher than San Diego pays for treated water outside the county, and

  • even though this plant is huge it can only make 10% of the county's needs.

  • And it'll use a lot of energy because it's forcing pressurized water through a membrane

  • to separate the water from the salt in a process called reverse osmosis.

  • It's drought-proof and doesn't rely on recycling a resource we're running out of

  • but as a practical way to solve California's water woes, it's more of a small puzzle

  • piece than the ultimate solution.

  • To put it in perspective, there are countries where water desalination is crucial.

  • Israel is one such country, and their desalination plants provide 35% of their drinking water,

  • or enough for 2.8 million people.

  • California's population is 5 times the size of Israel's, and the agriculture industry

  • is 32 times bigger.

  • 4 desalination plants may be fine for Israel, but it's not enough for the west coast.

  • Not by a long shot.

  • California also needs water urgently, so focusing more on conservation and recycling may be

  • a better strategy than building desalination plants that won't come online until at least

  • next year.

  • Like I said, we covered this topic because we got comments asking about it on our other

  • video about California's drought.

  • See, we listen to you guys.

  • We love you guys.

  • If you want to check out said video, here it is right down here.

  • And while you're at it if you have any other questions you want us to answer or topics

  • you want us to elaborate on, feel free to tell us in the comments.

  • I'm also on the twitters @JHug00, and until next time, thanks for watching DNews.
