Historic: China’s CO2 emissions have now been flat or falling for 18 months

Off-the-charts good

🇨🇳 Every second in China, an average of 100 solar panels are installed.

As of 2025 H1, they now have over 67% of the world's installed solar capacity.

Within this decade, China's solar capacity alone will surpass total US electrical capacity from all sources.

NEW: The first evidence of a solar take-off in Africa☀️✈️

x33 rise in Algeria🇩🇿 solar panel imports in the 12 mths to June 2025, compared to previous 12 mths.
x8 in Zambia🇿🇲
x7 in Botswana🇧🇼
x6 in Sudan🇸🇩
x3 in each of Liberia🇱🇷, DRC🇨🇩, Benin🇧🇯, Angola🇦🇴, Ethiopia🇪🇹

Disruptive innovation is a term popularised by the American academic Clayton Christensen.

This is a prime example: learning effects lead to reduced cost of solar leading to more adoption resulting in more learning effects because of modularisation.

Killer graph @ember_energy

[Nicolas Fulghum @nicolasfulghum]

Time to update your priors.

2000: Electricity was confined to use cases like cooling, electrical equipment, lighting, trains etc.

2025: 75% of the global energy system can be electrified ⚡️

Transport, heating, cooling, industrial heat...it can now all be powered by electrons

[Nicolas Fulghum @nicolasfulghum]

EVERY YEAR we extract more material (coal, gas, oil) than the material needed for the ENTIRE energy transition...at massive economic and environmental cost.

The cost of the energy transition is discussed all the time.

What's often missing is the cost of not doing it.

[John Raymond Hanger  @johnrhanger]

Solar and battery techs now offer much more for much less!

Solar cell efficiency surges as PV module price drops 99.6% since 1980!

Battery cell density skyrockets, as battery cell price plunges 99% since 1991!

So, Electrotech is often low cost.

China's National Computing+Energy Strategy:

This is the layout for China's national computing strategy. Under the "East Data, West-Computer" 东数西算 slogan, high-priority tasks are handled by local clusters, while lower-priority tasks are outsourced to the energy-rich west.🧵

Breaking: The value of China’s exports of clean energy technologies hit a new all-time record in July, passing the previous high from March 2023. China exported $18.4 bln worth of solar and wind power equipment, EVs and batteries during the month.

[Nicolas Fulghum @nicolasfulghum]

NEW | China installed more than twice as much solar capacity in the first half of 2025 as the rest of the world combined ☀️

256 GW in just six months... 🤯

The rest of the world combined installed 124 GW.

[John Raymond Hanger  @johnrhanger]

Solar repays its upfront CO2 debt from manufacturing in 4 months and 57 times over its life!

Solar is 19x cleaner than coal per kWh.

Solar is 8x cleaner than gas per kWh.

Wind and nuclear are even cleaner than solar.

Gas is dirty, not "clean!"

Chinese solar PV now really taking off across Africa. Very obvious inflection point in 2025 for many countries.

[Dave Jones @CleanPowerDave]

Almost every African country is now importing Chinese solar panels - and a LOT of them.

100MW may not sound a lot, but in context of the low levels of electricity supply in some countries, 100MW is pretty mahoosive..

[Jan Rosenow @janrosenow]

I don't think we fully grasped yet how important solar will be as an energy source.

Great graph @CarbonBrief based on @IEA data.

Total energy investment has risen in the past decade, but spending remains uneven globally

China, the US & the EU saw strong growth, while many developing economies, especially in Africa, are struggling to mobilise capital for energy infrastructure 👉 https://t.co/0ah51IX68F
