The growth of grid-scale batteries in the US continues to explode.
Over the last 12 months, the country added 13.2 GW of battery capacity—50% more than a year ago.

China built more solar in 6 months than the U.S. has — in TOTAL.

Renewables lower bills. They have no fuel cost and covered all of Texas’ significant demand growth so far this year.
But I get this question all the time: “If renewables are so cheap, why are my bills going up?”
The biggest drivers of higher power prices are:
⚡ Distribution costs (the biggest factor by far)
⚡ The cost of natural gas, particularly in 2022
Consider this: states like West Virginia and Alabama — with almost no renewable energy — have seen electricity bills climb much faster than Texas: 50% more over the last 6 years.
That wouldn’t be true if renewables were the problem.
And looking forward: gas prices are projected to rise again, especially as liquefied natural gas (LNG) exports increase. That’s one of many reasons why renewables are so important. Once you build them, the “fuel” is free. Every megawatt of solar and wind added lowers the need for gas, driving down overall costs for consumers.
So yes, prices are going up. And renewables are making power bills lower than they’d otherwise be. The more we build, and the higher gas costs go as LNG exports expand, the bigger that impact becomes.

Investment in grids is lagging behind spending on power generation & electrification, posing risks for electricity security
Grid investment needs to rise to keep pace with power generation spending by the early 2030s to ensure electricity security 👉 iea.li/43FIxCN

One of the key challenges we face in the US is connecting new power projects to the electric grid.
And one state does it better than anyone else: Texas.
The rest of the US can learn a lot from how the state's grid operator brings new projects online.

Worldwide, 380 GW of new solar capacity was installed in the first half of this year, marking a 64% increase from 2024, according to a report from the clean energy think tank Ember. China led, adding 256 GW.

Porsche claims they will be the first automaker to offer wireless charging for their EVs
The electric Cayenne will be the first Porsche that can be ordered with a charging coil on the vehicle starting in 2026. The unveil will be at the end of this year.
The 11 kW charger is what Porsche calls “one box” meaning aside from the charging pad on the floor pictured below, there’s no need for a separate wall box or control unit.
Porsche claims the efficiency of the unit is up to 90%. Data shows that owners of electric Porsches already charge at home about 75% of the time.
This will be an optional add on for the Cayenne that you have to pay for, so not all Cayennes will support it. The car will actually lower itself down automatically to get close to the charging pad.
The floor plate weighs 50 kilograms (110 ponds) and is equipped with both WiFi and LTE for software updates.
Wireless charging will launch first in Europe, with other markets to follow.

Solar and wind do NOT make electricity more expensive.
Mandates, red tape, and manipulated price signals do.
.@SecretaryWright: "When you add wind and solar onto a grid, you don't remove the need for coal plants, nuclear plants, and natural gas plants. You just end up having to maintain two grids. Maintaining two grids is ALWAYS more expensive."

If we want to champion transmission expansion we need to kill the snapshots showing discrete moments of basis and progress to showing cumulative basis
The payback comes from the area under the curve - X discourse is perpetually confused on what the objective function is here

Last year, China installed more solar than the rest of the world combined.
This year, more than twice as much.
China now has the tools to tap Earth’s largest energy resource at scale.
If we don’t build those tools quickly, we will be left behind.

Solar will be the largest global source of electricity by 2033 & wind will be second largest by ~2035!
Global solar generation will quadruple from 2023-2030!
Why are petrostate politicos freaking out?
See below & EVs.
EVs may displace 6 million b/d of oil by 2030.

I don't think we fully grasped yet how important solar will be as an energy source.
Great graph @CarbonBrief based on @IEA data.

The battery boom has begun🔋⚡️
69 GW were installed in 2024. That's 66% more than in 2023.
Battery storage is modular, flexible, fast to deploy and prices are still falling.
Its growth trajectory looks more like consumer electronics than traditional infrastructure.

A rise in greenhouse gas pollution from fossil fuels — particularly in the US — was a major factor in pushing global emissions higher in the first half, according to a report bloomberg.com/news/articles/…

Don't worry UK 🇬🇧, you don't have to choose between wind OR solar, they work well together! 🍃🤝☀️
There are very few days with both low wind and solar generation across the year.
