Let's hope someone can do the same for grid-scale seasonal storage. "Excess" solar electricity won't be free in (noon, summer) if you can easily bank it for (night, winter).

Power travels near the speed of light. In theory, the entire globe can be connected and countries with daylight can supply those at night in a cycle.

Do we have good enough conductors for that?

Regional grids are connected via tie-lines, and I heard international grids are also starting to become more connected in this way too. Though, I'd imagine it's complicated to send power from one side of the planet to the other. For starters grids can have different frequencies that need to be converted between. Also all transmission lines are subject to loss factors. In addition all the intermediary transmission companies have to route the power and avoid congestion on their grids, Then you have deal with all the financial settlement of the wheeling charges, which if you have to go through multiple grids and multiple currencies sounds like fun to deal with.

My understanding of the intentions of connecting international grids is for things like emergency supply of electricity to a different grid to stabilise the frequency and prevent blackouts.

For years I've been hearing one excuse for the US not doing more about climate change is that China is polluting more and if they aren't doing something about it then why should we? The argument always seemed disingenuous. For sure, China produces a lot of pollution as they are modernizing, but they are also investing a lot in the direction of sustainability. If we take the balance of (pollution produced - pollution…

I am not familiar with Chinese politics or motivation, but I wonder if it's for the same arguments we have in the US, "save the world" vs. "the strong can do whatever they want". I am not sure China does for the sake of sustainability and environment. Yes I know the end result might be the same but are the reasons the same?

I keep hearing this argument (that China does not care about climate change or the environment so it must be doing it for other reasons) but I just don't understand it. Why would you think they don't care about these things?

The Chinese leadership understands several things very clearly:

- The country has experienced multiple catastrophic natural disasters in the past.

- Such disasters often lead to regime change (losing the mandate of heaven via natural disasters leading to social unrest)

- The leadership is comprised of smart people (and a lot of engineers) and they don't play dumb political games like denying the reality of climate change.

- Climate change will bring far worse problems in future, which threatens the country's economic growth and therefore their hold on power.

So they have massive incentive to care about the reality of climate change and do everything they can to mitigate it and protect their environment.

This is the “smart grid” idea, right? We just haven’t fully explored it yet. Something I firmly believe is that there’s a ton of low hanging fruit for timing our energy use better. It is just hidden by the desire to present a uniform energy price. Like why not run our water heaters when power is cheap? Then if that became a thing, we might even be interested in larger water heater tanks. Batteries cost per volume, yo…

Power at peak times is cheap because load is distributed throughout the day. If everybody ran their heaters at the same time, power wouldn’t be so cheap and we’d reach the same situation we’re in.

If power wasn’t cheaper, there’d be no incentive to run our heaters at the same time. I’d expect the market to work this out, and price power down during unexpected over-supply, rewarding nimble workloads. Then there arrives a reward for being nimble, which is something we should incentivize I think.

still sounds like an incredible way to incentivize consumers to buy small-scale storage. if i knew i could get free electricity for an hour or two each day (or even each week) it'd be a very easy choice to drop ~$1000 on a home battery.

You'd spend $1000 to save $0.20 on electricity every day?

7.3% return, not bad. As battery prices drop it will get even better.

Ignoring the politics, we have to say that China has done the world collectively as a whole a major service in strategically developing and mass producing super cheap solar panels.

How is that even remotely related to this topic or to what OP said? Or do you just have a thing you want to rant about no matter the topic?

Power at peak times is cheap because it's the time of highest insolation.

And they actually charge you a fee if you generate. My brother in law unhooked from the grid because back feeding was charging him $100 a month. To give away power.

A friend of mine is trying to build a house in a remote area of Southern California. He's planning to be completely "off-grid", generating power exclusively from solar. However, local regulators insist he hook up to the local electric utility. Further, in order to run the electrical cables to his property (from the substation), the local fire department insists that the brush is cleared around the new electrical cabl…

It gets even crazier. Latest: he's got a lawyer that says if he plants trees on a certain percentage of his property, it can be classified as a farm, and then exempt from the power utility hook-up requirement. But that comes with its own requirements, like a well to get water and certain fencing. But yeah, keep in mind, this is all so a dude can generate his own power on his own property.

For some reason when I read that I thought it was offering anyone in the world free electricity, and I started imagining the USA setting up a giant undersea cable... then I realized the voltage drop would be too high, then finally realized they meant it for Australians only!

Now I'm imagining drilling through the Earth to get the shortest possible line from Australia to my house. I like this
