#China has powered up the world’s largest open-sea offshore solar farm - https://www.theguardian.com/environment/live/2024/nov/15/cop29-live-day-five-begins-with-demands-for-change-to-way-summits-are-run?page=with:block-6736fc528f088965fc622062#block-6736fc528f088965fc622062 "one gigawatt (GW) offshore solar farm – the world’s first and largest of its kind" #renewables

"It took 68 years for the world to reach 1 terawatt of solar PV capacity. It took just two years to double it"

@cstross We need a Moore's law for #Renewables.

#Introduction

I'm Tim. I worked in #Software for 37 years at PAFEC, CA, Mediasurface, Sun & twice for Software AG.

My interests include #RetroComputing, #LibDem #Politics, #Psychology, #Renewables #Gardening & Gnu, my #Caterham7.

I write three blogs.

One on #RetroComputing - https://z80.timholyoake.uk/

A second on living with #BloodCancer, #MCL - https://mcl.timholyoake.uk/

And a third documenting my fundraising for Lymphoma Action - https://railwaywalks.timholyoake.uk/

Be seeing you 🙂

Also also. With #Trump coming up, is the dependency on US LNG sustainable? The move to #Renewables and storage capacities for electricity can not come soon enough, IMHO.

Plans for biggest onshore #windfarm in England to be submitted this week - https://www.theguardian.com/environment/2024/nov/05/biggest-onshore-windfarm-energy-cubico-scout-moor-greater-manchester "Cubico project at Scout Moor near Greater Manchester could power the equivalent of 100,000 homes" good to see some movement, finally #renewables

Oh look - the UCP is looking to expand its de facto ban on renewables.

I had a discussion with an economist about the UCP's approach here over on X a month or two back. He tried to argue that it was "good policy" because it went after end of life recycling issues.

I said it was part of a de facto ban, and here we are with that being expanded.

I'm sure you're all surprised by this.

Renewable distributed power is radical. It would transform the world.

Good to see the Netherlands on #2 with 77% #wind and #solar electricity by 2030!
Between Denmark and Germany.

Even solar energy’s biggest fans are underestimating it

> We’re still underestimating the potential for solar power. New data shows how rapid solar energy expansion has become.

Possible for #Japan to increase from present 22% #renewables to 80% by 2035 by increasing battery storage and grid transmission while phasing out coal and nuclear, new study says
#energytransition #ClimateCrisis https://mainichi.jp/english/articles/20240922/p2g/00m/0na/020000c https://mainichi.jp/english/articles/20240922/p2g/00m/0na/020000c

While calls are growing for #Japan to prioritize #renewables, #China’s dominance of key components – such as #lithium, cobalt #solar & nickel – is linked by forced labor of #Uyghurs in the #Xinjiang region and other #humanrights concerns in places like #Indonesia and the #DRC.

For my story for @thejapantimes I explore how Tokyo is balancing with the social cost and geopolitical risks as it, cautiously, moves forward on its #cleanenergy transition

On Wed: German Foreign Office posted on X mocking #TFG.

TFG criticized Harris’s clean energy approaches -cited Germany.

“Germany tried that & within 1 year -back to building normal energy plants. We’re not ready for it -can’t sacrifice our country for the sake of bad vision” -TFG.

Germany refuted that claim: “Germany’s energy system is fully operational, with >50% #renewables. We're shutting down coal & nuclear plants. Coal: off the grid by 2038 at the latest.”

More positive #climate news:

Big battery market charges beyond expectations, now the grid just needs more wind and solar. #Renewables #ClimateCrisis https://johnmenadue.com/big-battery-market-charges-beyond-expectations-now-the-grid-just-needs-more-wind-and-solar/

#Russia today attacked Kyiv Hydro Power Plant in #Ukraine with rockets and I can’t pass this opportunity to demonstrate another popular media bias related to electricity generation.

Kyiv HPP reservoir is almost 1,000 km2 and the dam is 12 m high with a capacity of 1,500 m3/s. The potential energy of this mass of water is 1.5 GJ, or - if one likes comparisons to nuclear weapons - roughly half a kiloton of TNT per second. In terms of energy released, it’s like a small tactical nuclear weapon exploding every second for days, until all water escapes.

While everyone is getting excited about a hypothetical #nuclear meltdown in Zaporizhzhia or Kursk, the risks of #renewables have already materialised - the Russian destruction of the Novaya Kakhovka hydroelectric plant resulted in the deaths of hundreds of people and the contamination of thousands of km2 of land and the Black Sea. The Russians have already attacked hydropower plants in Dnipro and now Kyiv, and have successfully stopped power generation (but not destroyed the dams themselves). Historically, the biggest energy-related disaster is also not any Chernobyls or Fukushimas, but also hydroelectric plants - the destruction of the Banquiao dam chain in China in 1975, which killed between 50’000 and 200’000 people.

The story of the Russian invasion of Ukraine shows that renewable energy - and hydropower is one of the key renewables because it’s dispatchable - is a source of risks not just hypothetical, like NPPs, but real.

Please do not take what I wrote above about kilotons as an attack on renewables itself, just me poking the media bias and a polite reminder that any source of energy is a potential threat. A sound analysis of the risks associated with these sources involves a quantitative comparison of these risks converted into kWh of energy produced based on facts, not mythology wholesale manufactured by Greenpeace & friends.
