This is the version exactly as it was saved, character for character. The SHA-256 hash below is a 64-character code worked out from that text. Run the same text through SHA-256 and you get the same code; change a single letter and the code comes out completely different. Each version also stores the previous version’s hash, which chains them together so no version can be swapped out quietly.

headline: AI datacentres plan on-site power stations on huge scale despite climate risks, research reveals
dek: Developers of AI datacentres plan to build on-site climate-destroying gas power stations on a huge scale to meet their energy demands, research reveals. Datacentres planned across the US, the UK and mainland Europe have proposals to build fossil fuel plants on-site to create 181GW of gas-fired capacity because of delays to connect to national grids, according to the findings. This is almost four times the total peak electricity demand of Great Britain. The research by BloombergNEF says this “speed to power” will…

quick_read: BloombergNEF research found that datacentres planned across the US, the UK and mainland Europe include proposals for 181GW of on-site gas-fired capacity, driven by delays in connecting to national grids. That is almost four times Great Britain's total peak electricity demand.

If the rollout happens, the US plants alone would emit about 345m metric tonnes of CO2e a year, equal to about 72.8m fossil fuel cars. The US accounts for 90% of the planned on-site gas stations. The report was published as the 31st UN climate summit opened in Turkey.

BloombergNEF projects that AI datacentre electricity demand will almost quadruple by 2035 to 2,354 terawatt-hours, or 7% of global demand. Its analyst warned that developers' claims the plants are temporary may not hold once the economics favour continued generation, creating a risk of fossil-fuel lock-in.
limitation: The 345m tonne emissions figure applies only if the planned rollout happens, and developers say the gas plants will be temporary while they await grid connections.
tag: Evidence-backed problem
key_points: The proposals total 181GW of on-site gas-fired capacity across datacentres planned in the US, the UK and mainland Europe. | About 90% of the planned on-site gas-fired plants are in the US. | BloombergNEF estimates about 345m metric tonnes of CO2e a year from US plants if the rollout goes ahead. | UK datacentres made more than 100 inquiries in 2024-5 to connect to gas, according to Future Energy Networks. | Wapseys Wood in Buckinghamshire and Quest Park in Bedfordshire are seeking their own on-site gas plants because of long grid waits. | The chancellor, John Healey, approved temporary on-site fossil fuel plants for datacentres waiting for grid connections, as part of a datacentre covenant. | Global Action Plan's Oliver Hayes said no one seriously believes the gas plants will be temporary.
rundown: The research ties the gas plans to speed to power: developers are building their own generation because grid connections are slow. BloombergNEF's Mark Daly said the climate outcome depends on how much electricity the facilities use, how quickly grids can connect them and whether cleaner generation is added alongside that demand.

In the UK, Wapseys Wood and Quest Park are among the first datacentres fast-tracked through the nationally significant infrastructure project regime. That regime lets developers bypass locally elected planning authorities. The chancellor's backing for temporary on-site fossil plants is likely to see the approach repeated at more UK sites.

The report said connecting new datacentres to the grid is the more sustainable option, and that faster connections are central to limiting emissions and fossil fuel lock-in risk. Campaigners called private gas stations for datacentres a red line for any government serious about climate action.
