Unfortunately, I can't share your enthusiasm. These are just pledges and hollow "commitments" which nobody can enforce. China’s construction of new coal-power plants ‘reached 10-year high’ in 2024 The country began building 94.5 gigawatts (GW) of new coal-power capacity and resumed 3.3GW of suspended projects in 2024, the highest level of construction in the past 10 years, |

One small step to come here in the UK: UK fracking ban to be brought forward as Labour counters Reform promise wrote: ... the government is to speed up its plans to permanently ban fracking in the UK, in order to counter the Reform party’s promises to bring back the controversial practice...

Here is a brief presentation for turning to 100% renewables: Greg Jackson explains how energy giants suppress renewables | Climate 100 The interesting part comes in the extended discussion that covers the economics and politics and a tremendous positive shift in convenience. There really is a good clean convenient efficient way to go! So astonishingly cheap it is all a no-brainer! And some of us are going well right now.

Only if the UK does not substitute domestic shale gas with imported LNG.... to ban fracking "at the earliest opportunity" to protect the 187 constituencies that sit above shale gas areas from drilling...A multiple win against pollution and needless costs... https://www.ons.gov.uk/economy/nationalaccounts/balanceofpayments/articles/trendsinukimportsandexportsoffuels/2022-06-29 The UK imports around 50% of its gas from the international market and most homes in England and Wales are heated by mains gas supply. Gas is also used to fuel around a third of the UK's electricity generation, so rising gas prices will usually lead to rising electricity prices. |

Can't argue with this: Wind power has cut £104bn from UK energy costs since 2010, study finds wrote: Reduction comes from energy generated from windfarms and lower cost of gas owing to lower demand [for gas due to that wind power being used instead]... ...

But, Miliband admits wind power less reliable than expected Energy Secretary would have to pay higher subsidies, making it harder to reach clean power targets The Government has slashed forecasts for the amount of electricity it expects wind farms to generate in a blow to Ed Miliband’s net zero plans. |

Since 2015 (no publicly available data before) the UK imported on average 17...19 TWh (billion kilowatt hours) per annum. Since 2021 imports increased to 25 TWh; after that, in 2024 a staggering 34 TWh was imported from the continent and Scandinavia. The only exception in 2022: a net export of 5 TWh (due to downtimes of too many French nuclear PPs). The UK is the 2nd largest importer of electricity in Europe, chasing longtime champion Italy (>50 TWh per annum) which stopped its Nuclear PPs already in 1987 (because of Chernobyl); never replaced their generating capacities).... but still before the 3rd, Germany, which became a major net importer due to its nuclear phase-out in 2023). We will outpace the UK as soon as our coal and lignite phase-out picks up speed in a couple of years; or even earlier, depending on CO2 pricing... Lignite is most CO2-extensive, so becomes inreasingly more expensive than gas; second only to diesel resp. fuel oil, which is only used on off-grid islands (e.g. Spain's Canary Islands, Danish Faroyar, or Cyprus). Grid scale electricity, traded at energy exhanges is 'grey-labeled'. Simply import your electricity needs and get rid of further green energy requirements. It's the business of the supplier, no longer yours. There's a general assumption in Europe: Sufficient electricity is available all the time at exchanges, so don't worry.... day ahead and intraday trading can balance demand and supply, while minimizing your costs... just provide high-capacity interconnectors to all your neighbours. Isn't that great? (It is!) But what if too many prefer to import? Who can supply them when it gets dark and calm? Which countries possess reliable and cheap green capacities, capable to export vast energy on an annular balance? Today, it's just France, Sweden, and Norway... and unfortunately, the French nuclear fleet ages fast... Can they replace it soon enough? https://www.energy-charts.info/charts/import_export_map/chart.htm?l=en&c=DE&year=2024&interval=year |

... green energy subsidies... ... Except, what is not mentioned, are the insane subsidies we are all paying to subsidize oil and gas and the eye-wateringly most expensive nuclear power in the world. Also note that the wholesale price of electricity is determined by the price of gas, even though that is no longer dominant! Old oil profits linger on... And on... (The grid business model needs to change so as to relegate the dirty old fossils to be paid to be NOT used but instead to be available as 'backup generators'...) Instead, go cleanly!

Thanks for that. And this will warm the feet of many: Meet the biggest heat pumps in the world wrote: ... "There was a lot of pressure on us to change the heat generation to new sources, especially renewable sources," explains Mr Hack as he discusses the decommissioning of coal-fired units at the Mannheim plant. The site is right by the Rhine, already has a hefty electricity grid connection, and is plugged in to the district heating network, so it makes sense to install the heat pumps..." ... For a very obvious cleaner upgrade. Shame about the high initial cost, but thereafter the running costs will be greatly reduced, cleanly! All on our only one planet...

Oh Wow... There are currently construction works ongoing for a 725 km long subsea HVDC interconnector (525 kilovolts, 1.4 gigawatts) crossing the North Sea and connecting Wilhelmshaven/Lower Saxony in Germany with the Isle of Grain/Kent, England. https://neuconnect-interconnector.com/about-us/ Costs: €2.8 billion / £2.4 billion. For similiar projects, e.g. "NordLink" that connects Germany with Norway cost figures were given as: 50% for cable manufacturing and laying; 50% for two giant HVDC/HVAC converter stations at endpoints. Commissioning planned for 2027. Open Infrastructure Map |

Hey! Wow! I'm surprised that the connector stations are so very expensive... I thought it was the reduced costs of the big semiconductor devices that had made the HVDC connectors a no-brainer good to do... All across our only one planet...
