Fascinating tech, but 2400°C molten tin just sounds scary.

TL;DR if battery technology and price continues its current trajectory, households will be able to store all the electricity they need at a price that is similar to the solar panels on the roof in just a few years from now. https://shkspr.mobi/blog/2025/09/how-big-a-solar-battery-do-i-need-to-store-all-my-homes-electricity/ by @Edent

So yes Bill has talked for many years about supporting a positive vision (a bit like my architect former employer Bill McDonough) which I have brought with me in everything I do. It is not enough to be against failure and suffering, we must be for something and then it takes time and work and money to make that good thing happen. #progress
And yes, zoning is of course a powerful tool to block needed improvements, enforce scarcity and super charge inflation. I spend most of my time thinking about housing, but this is becoming increasingly relevant in the energy space as federal, state and local government actors race to shut down a variety of needed energy projects planned or underway, including #solar . I like Bill’s idea of legalizing balcony solar as #Utah has done

Good news for your Monday:
Solar is winning globally, and globally is what matters:
"Global solar installations rise 64%, to 380 GW, in first half of 2025"
- China installed the most
- India was #2
- US was #3, despite 🍊
Very good that the most populous countries are also installing the most #cleanenergy

Chinese solar and wind manufacturers are not only driving a massive buildout of renewable energy in China but also propelling a rapid shift away from fossil fuels in much of the developing world, according to a new analysis.
The result is that many emerging markets are now outpacing the U.S. in the shift to renewable energy, including Brazil, Chile, El Salvador, Morocco, Kenya, and Namibia.

China’s solar, battery and electric vehicle companies have expanded their foreign investment plans in recent years, having pledged more than $210 billion since 2022. https://www.japantimes.co.jp/business/2025/09/10/tech/china-green-tech-overseas-factories/?utm_medium=Social&utm_source=mastodon #business #tech #china #renewables #wind #solar #energy #batteries
Use of fossil fuels could begin to drop in about five years' time thanks to China’s rapid adoption of renewables and its increasing reliance on electricity, clean-energy think tank Ember has said. https://www.japantimes.co.jp/environment/2025/09/09/energy/china-green-push-global-fossil/?utm_medium=Social&utm_source=mastodon #environment #energy #china #renewables #fossilfuel #wind #solar

H1 2025: China installs more solar than rest of the world combined.

At a very conservative (for solar) 20% growth rate this means that, by 2030, solar will have added 200TWh capacity to the combined African grid and will be adding 1/5 of Africa's current coal generation capacity annually. Even without much storage (which there will be) this will make a massive difference to African homes and businesses.
All the other clean options will still be getting out of the gate by then.
This is the _start_ of the growth story not the end.
Solar & then Solar + Storage is the only technology that can drive just & clean access to electricity in the Global South. All other solutions require centralised control, large capital outlays & long lead times.
Solar is here now, it is cheap, it can be deployed locally. It is easy and fast to buy & deploy at any scale.
We now have the means to build & ship them at scale (Thank you China). Potentially making all new generation clean & available to all.

Solar is taking off across Africa.
In the 12 months through June 2025, over 15GW worth of solar panels were imported. This wave is happening across the continent: 20 countries have set new import records.
Sierra Leone imported enough solar panels in one year to make up 65% of their entire nation's generating capacity.
If you're not preparing for significant drops in fossil fuel demand, you're not paying attention!
