With solar energy prices plummeting, it may make sense during peak production hours to use it to do desalination and/or extract water from the air, depending on where you are.

It's like trying to use a hammer to screw some bolts. The priority should be sustainable development. We have enough water, just not great usage. The water infrastructure we have today is aged and needs to expand to allow for the population growth the country has seen. On top of that, we are expanding cities in parts of the country where water is scarce. We are growing water intensive crops in parts of the country th…

We may have enough water for now but we're using it faster than it can be replenished; our reserves in aquifers is starting to run out.

I watched the documentary Day Zero [1] last year about the global water crisis. I highly recommend anyone interested in what's going on with water to watch it. It was one of those oh shit movies where on one hand, you're glad you learned something important and on the other hand, you kinda wish you could have stayed blissfully ignorant because of how scary the situation actually is.

For example, the Ogallala Aquifer [2] covers approximately 174,000 square miles across 8 states—South Dakota, Nebraska, Wyoming, Colorado, Kansas, New Mexico, Oklahoma and Texas. It's one of the largest aquifers in the world.

Of all the water that's extracted from it, only 10% gets replenished. That's obviously not sustainable, especially with climate change, increasing municipal and farming use.

We're not going to desalinate our way out of this all over the world.

93 billion gallons of fresh water falls on Los Angeles every year. (12 inches / y over the whole surface area[1]) They have ~2 million households[2], and a household uses an average of 3,000 g/m or 36,000 g/y/h or about 80 billion gallons / y for all households. Huge coincidence, that's pretty close to balanced out. And yet, we shuffle the rainfall to the ocean and pray for snowpack in the mountains and protest Nestl…

Only a fraction of that can be captured

Why is that? If it is slowed down and sunk into the earth it would add to the aquifers, no?

Water is a lot easier to store than electricity. Desalinate while the sun is shining to fill a reservoir that you can pull from 24/7.

True, but it isn't energy, and desal requires firm generation, so you're not using renewables that would've been curtailed but instead competing with load that needs consistent power. Still hopeful considering the cost decline curve of utility scale storage, but it isn't a silver bullet based on solar being free at noon.

You combine the desalination with pumped hydro storage. Or you just deploy it with intermittent power, as the other poster pointed out. https://spectrum.ieee.org/amp/pumped-storage-hydropower-2666...

That is a positive trend, but a few good marketing campaigns can increase eating beef again.

> That is a positive trend, but a few good marketing campaigns can increase eating beef again. It's not that simple. Millennials don't eat meat in the same quantities as their parents did and that's not going to change any time soon. Also, this generation is basically allergic to typical marketing campaigns. They also get how eating meat is detrimental to the environment, something they care a lot about. "Notable Mil…

>According to other research sources, a total of 96 percent of millennials say they replace a meal with a snack once a week, and 58 percent say they snack 4-5 times a day!

O&G won because the energy density is so extremely high.

Gasoline may be a lot more energy dense, but ICE are about 20% to 40% efficiency while electric motors are about 60% - 80% efficient. So the differences aren't as great as you might think. If we hadn't just jumped at gasoline and money hadn't flowed so readily towards that tech, there's no telling how far battery tech would be today. A lot further than it is now, I have no doubt. The fact is that big oil has killed o…

In response to the now deleted response questioning "how can we mine lithium without fossil fuels" ...

Rio Tinto (mining since the pre Roman gold mines at Rio Tinto in Spain ... (alledgedly)) are already transitioning to hydrogen and renewables on their iron ore (and other) mines that move ~ 800 million tonne per annum from Western Australia (that's something like 4x greater than peak mining for steel in the US ever reached in a year).

But where does the water go? It can't simply just vanish. It's a capacity problem, right? Also who cares who eats the beef? If you price in the water usage then these people eating all the beef will either keep eating and pay for their use or stop. Don't blame people for enjoying their life. It's akin to blaming people for using electricity when it is powered by coal...

>But where does the water go Not back into aquifers, that takes hundreds if not thousands of years. >Also who cares who eats the beef? If you price in the water usage Ya, that's kinda the point, we don't. If we removed the massive subsidies propping up ranching very few people would be consuming beef. >Don't blame people for enjoying their life I don't think I did, but as you brought it up. I'll absolutely shame peop…

Yeah so they're not back into aquifers, but so what. Where is it going if we aren't reusing it? Into the ocean? That is the only reasonable explanation. Unless it's physically leaving Earth which I doubt but also it could be true, who knows.

So remove them. Stop crying about cows or the medium, they aren't related to it. It's purely a regulated movement problem.

You are talking about who is eating the meat. It is totally irrelevant unless you are there to single them out and blame them.

So you're blaming who, the people eating or the "boomers" regulating it so they can eat? Right now it sounds like the people eating. Consumers aren't the problem. If you give people things they enjoy they will consume them, that isn't new science, and so they should.

The remark about who eats the beer is about the fact baby boomer generation is in full swing retirement wave. As they retire they switch to fixed income and as they age, they will consume less beef, because their bodies won't keep up. Basically if demographics hold, then the US will see a drop in beef consumption in 5 years and in part, more water conservation lol

What does that have to do with water conservation? It's not water conservation it's water usage that's going down.

If you fill your car tank and don't drive, you're not conserving it because it's still going to drain just as fast when you do drive. The car has already got the water in there. You won't take it back out.

Huh?

The newest generation is the easiest that's ever been to advertise to. The medium has just changed...

Regardless, as I understand it, it's well-established that almond milk uses less water per gallon than dairy milk. However, we grow almonds in areas that don't have enough water, and milk is often produced in areas with surplus water. Either way, I prefer soy milk.

> Either way, I prefer soy milk. Are you at all concerned about hormone imbalances?

The estrogenic substances are not present in physiological relevant concentrations, its not anything to worry about
