Grid batteries reach stunning new peak of 44 percent of evening demand in California, the world's fourth biggest economy by GDP
Grid batteries reach stunning new peak of 44 percent of evening demand in California, the world's fourth biggest economy by GDP
This is good news. Solar is the way to go, if there’s a way to supply nighttime demand, and batteries are one solution. Solar panels are cheaper, more efficient, and last much longer than wind turbines. We really should replace wind turbines with solar panels and batteries, or some other method of storing the energy.
However, none of this seems to matter, if the ignorant masses keep getting duped by the billionaires.
Indeed, in the UK (a notoriously windy place) wind currently far outpaces solar in terms of energy production and although it’s also variable, it works well in winter and at night.
During summer solar really shines (no pun intended), but wind absolutely rocks.
From GP comment:

That’s wrong, wind can provide a steady energy source (you see that in the plot from the OP article), it is available during the night and, depending on geography, can match some energy demand quite well.
It is not competing, it is complementing each other in a way that less storage is needed.
For example, in coastal Northern Europe, there is lots of wind power in winter, when electricity is needed to power heat pumps.
California specifically has a long coast line exposed to west winds from the Pacific ocean.
Batteries complement these.
An ideal fourth complement would be wave power like the Pelamis type. (Pelamis was shelved by E.ON, a fossil energy company, but probably copied by the Chinese.)
“fossil fuel economy is finished” is such a polarizing oversimplification. It will still have its uses for a long time.
Instead of dramatic statements, can we have more positive perspectives like “grid batteries really work, here’s some proof”

The problem with fossil fuel economy is that it depends on economies of scale. The less we use them, the more expensive it gets to use them. So it’s a feedback loop that might really accelerate the downfall of fossil fuels faster than expected.
This.
Fossil fuels do have huge costs.
The fossil fuel economy has their own feedback loops: Energetic ones - energy is needed to extract oil. And lots of cheap capital - this is why the 2008 financial crisis was linked with an oil price crises - and caused a severe crisis in the worldwide car industry.
All this isn’t helped by the fact that most of the cheap oil that the world had, was already extracted. Oil extraction becomes more and more expensive.
Politically, I think it is a kind of power system that stabilizes itself. Like the old UDSSR’s system. You know what happened with the Sowjet bloc? it collapsed, within the five years from 1984 to 1989.
Or, to take a less dramatic example, the tobacco industry. A few years ago, smoking in public was normalized. It isn’t any more. But before the switch happened, tobacco companies put absolutely huge amounts of advertising, manipulation, false research, bribery and political shenanigans to keep it that way. Wait, did I say this example is less dramatic? I have to correct myself: about 100 million people died as a effect of tobacco smoking in the 20th century. (Yes, these are more deaths than from WWII).
At some point, continuing the fossil economy gets too expensive. You see that, ironically, in Iran: Mass protests because in spite of the heaps of money moved, the population lacks proper food and income.
And in the US? Very few very rich people, and many which are barely scratching by. Fossil companies there now support an authoritarian state. Why? Because, like tobacco companies, they don’t want that change that is inevitable in a democracy. Before these lose the game, they will smash the game table. It is similar to military companies financing fascist parties in Europe after WWI. After that catastrophic war, social democracy was on the rise, and people supported that another war was madness. The League of Nations was formed, to promote peacful conflict resolution.. These military companies could not see how to make money in a peaceful cooperation of nations, so they tried to support fascism which strived to turn the clock back.
The thing is - at some point, these feedback loops come to a halt, and go into an reverse cycle. For example, less profit means less bribe money. Which means less influence. Less cheap oil resources means more expensive oil and gasoline. Which means less demand from car users, because they switch to electric cars. Which means less filling stations, and (in Europe) cities less geared towards cars, and so on.
The rising of cheap renewable energy and storage technology is only accelerating that. Oil extraction is getting more expensive, political and societal costs are rising (who wants to have a family member dying in Iran?), and the alternatives are becoming cheaper.
My take is that we will now witness a quick and swift change into another system. We will also see a huge re-adjustment of economical weights.
The way we organize and distribute power, in every sense of the word, will profoundly change and will be completely re-organized within no more than two decades. Possibly only ten years.
By the way, fossil hydrocarbons as an input to chemical products are harder to replace, and this will happen later. But also in such uses, some quick gains are possible. For example, single-use plastics can be replaced by re-usable food containers. In Germany, we do that with beer bottles, he.
This is another view on what happened on Sunday in California. Batteries charged heavily throughout the day, soaking up the excess solar, approaching charging rates of 10 GW at times. In the evening, most of the output was centred on the early evening peak, but batteries supplied a significant share throughout the evening.
The biggest loser in this transition has been gas, with the share of battery storage staying at high levels throughout the evening peak. On Sunday, it stayed above 20 per cent of grid demand for almost four hours.
As Fulghum noted: “To put that kind of output during peak demand hours into perspective, it’s equivalent to the output from:
It also opens up more drilling that wasn’t worth the expense before.
In theory yes. But while fracking is a more short-term activity, developing an oil field, let alone sub-sea oil fields is a very capital-intensive and time-consuming endeavour. It is possible that, due to the rapid transition to renewables, the time horizon that is left for earning with such developments, is not large enough to take the risk. Especially since the oil fields in the gulf states, which were already profitable, will be re-opened within a few years.
Industrial developments typically have life times of twenty years. This is far longer than the time scale of the transition we can expect.
Also, the transition will be messy, not nice and tidy. In Germany, renewables have replaced nuclear first, only now they are replacing coal. The order might be different in the US, but then again things will become chaotic if due to cutting red tape a nuclear disaster happens in the US.
Things in the US will also be accelerated by the need to provide more power for AC in heat waves. That can go from an seemingly academic discussion to a question that is realized to be life-or-death quickly.
In Africa, solar panels are replacing firewood.
In Asia, countries are returning now to using coal as an emergency measure - but people know that this is only a temporary emergency solution.
South Asia also urgently needs power for AC, even more than the US.
China still builds coal plants, but they are designed as a fall-back to wind and solar, not as the backbone of supply. Which makes sense for them, because China has more coal than oil.
