Sky-high electricity costs, coupled with the piecemeal support successive governments have given to big industrial power user, are said to have made power prices an obstacle to the U.K.'s shift towards cleaner energy. https://www.japantimes.co.jp/environment/2025/08/28/energy/electricity-costs-britain-net-zero/?utm_medium=Social&utm_source=mastodon #environment #energy #uk #energy #electricity #coal #netzero #emissions #fossilfuels #renewables #wind #solar
Chinese government officials last month showed off what they say will be the world’s largest solar farm when completed high on a Tibetan plateau. It will cover 610 square km, which is the size of Chicago.
China has been installing solar panels far faster than anywhere else in the world, and the investment is starting to pay off. China’s carbon emissions may have peaked well ahead of a government target of doing so before 2030.

Puh endlich ist unsere große Wechselrichter-Geschichte erschienen. Sie ist voller Sicherheitslücken und anderer Angriffspunkte und mir ist mit jedem Interview und jeder Analyse klar geworden: es sieht nicht gut aus. 80 Prozent der Technik auch in privaten Solaranlagen stammt aus China und kann von dort fern gesteuert werden. Und es gibt Sicherheitslücken noch und nöcher.

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.
I expect Africa's demand to grow pretty much in line with supply.
Probably the only "transition" we'll see, rather than "addition" is from expensive diesel generators to solar and batteries (probably with diesel backups kept "just in case").
& an invisible one of human labour -> pumps.
& maybe of firewood to electric rings (but that will probably initially be to kerosene stoves TBH).
Additive when it is pulling people up from the bottom is not a bad thing.

What would it take for our home to be Solar Self-Sufficient?
Work in progress, but I think I have the answer.
🏠 I live in an ordinary house in suburban London.
☀️ Our solar panels generate 3,800kWh per year.
🔌 We use the same amount of electricity per year.
After crunching the numbers:
🔋 Capturing all our solar excess needs a 1 MegaWatt-hour battery.
"The solar panels imported into Sierra Leone in the last 12 months, if installed, would generate electricity equivalent to 61% of the total reported 2023 electricity generation" #Energy#Solar#Africa

This is encouraging. Its a shame we cannot tell how many are actually being installed. ( solar_chase@mastodon.green does you satellite ML stuff go small scale enough? )
This could initially go quite fast as diesel owners (i.e. not really low income) add solar to save money.) Though, as its already off grid tracking will be hard.
Hopefully there will be enough panels and and a growing skilled workforce to spread this out to low income groups.
Despite continued use of coal, China's energy landscape is rapidly decarbonizing. Renewables, especially solar, now account for over 80% of newly installed electricity-generating capacity, with costs plummeting below thermal power. While new coal plants are being built for local energy security, the clear long-term trend is a transition toward a cleaner, more efficient, and more electrified system.

Pakistan pulled off one of the fastest solar revolutions in the world by importing cheap panels from China.
What’s happening here undermines an increasingly popular narrative that clean energy is unaffordable, unwanted and can only succeed with large-scale government subsidies.

Somehow missed this:
Pakistan, home to more than 240 million people, is experiencing one of the most rapid #solar revolutions on the planet, even as it grapples with poverty and economic instability.
Suddenly about half the country’s electricity comes from solar. It’s not industrial solar farms or state-led: it’s a bottom-up revolution: households fed up with rising power costs and blackouts buying what are now ridiculously cheap solar panels.
