💯Batteries + renewables are the answer.
Grid scale batteries are changing our electricity system. Excellent visual story on batteries in FT shows just how far this technology has evolved. Fasten your seatbelts, this is just the beginning.

Illinois: $1 billion in battery investment will save consumers $13 billion in capacity costs.
This is what @JigarShahDC and I have been talking about the past years. As capacity costs rise while battery costs plummet, we will see more of this.

Batteries Save Illinois Consumers $12 billion!
The Illinois Legislature passes a big energy bill that will deploy 3 GW of battery storage by 2030 and more solar.
Battery storage will save consumers $12 billion by cutting capacity costs!

Batteries will solve this.
Europe's solar boom is breaking the grid
Unreliable renewables caused a record 8,645 voltage exceedances last year (up 2,000% since 2015)
This means power stations may disconnect, leading to system-wide blackouts like Spain
Experts warn "controlled blackouts will soon be needed"
The price of unreliability

'El CEO de Enagás asegura que transportar hidrógeno verde es una ruina e inviable económicamente, solo sustentado por ayudas públicas".
Por su baja densidad energética volumétrica, requeriría licuarlo a -253°C o comprimirlo a 700bar para ser práctico.

💯 Batteries + Solar (and wind and hydro)
ELON: WE SHOULD LEAN TOWARD A SOLAR AND BATTERY FUTURE
“I’d say the concern level for climate change is on the order of 50 years, definitely not five, and probably not 500.
The right course of action is simply the reasonable one, to lean toward sustainable energy, toward solar, and toward a solar-battery future.
The rules of the system should lean that way too.
We don’t need massive subsidies, but we also shouldn’t have massive subsidies for the oil and gas industry.”

China currently has 339 gigawatts of wind and solar capacity under construction — roughly two-thirds of the world’s total.
China is leading the clean energy revolution. That’s not a subjective statement; it’s a fact.

¡Sorpresa! Lo que ya dije hace unos días.
Las eléctricas admiten al Gobierno las limitaciones de las nucleares para evitar otro apagón.

£104bn saved by moving to renewables from @ucl study
It concludes that sustained investment in wind has significantly reduced overall fossil fuel dependence and household energy bills.

Solar is scaling faster than anyone modelled. The serial underestimators, the IEA, now say solar beats nuclear ’26, hydro ’29, gas ’31, coal ’32 — & could power everything by ’35. The fossil era is running out of daylight while the battery age looms. #LFP
