1 . Nature has the power to alter an element’s identity with time and space. This is evident by the transformative effect Britain’s deep coal mines have been showing after decades of being one of the biggest reasons for pollution. Now, they’re being employed to supply green energy to the town of Gateshead. The town is the first place to experience something like this in the country, but the success of the phenomenon has encouraged the authorities to apply it to other towns.
In 2021, coal was just producing 2% of electricity in the UK. Most of the electricity in the country is being supplied through oil and gas. This has resulted in massive abandoned coal mines all across the country. As years went by, these mines were flooded with water, making it a source of geothermal(地热的) energy, which is used to generate heat and electricity. Gateshead hosts such a mine in its town, whose council, therefore, launched a mine water project in March 2023.
The authorities put in a large central heat pump in the mine. Mine water can often sit with a temperature of 45℃. The water is then pumped using appliances to home heat pumps. The process increases the temperature further. The water then goes ahead and warms up the interior space and home water supply. After the heat from the water has been used, it’s sent back to the mine where it again goes through the same process. The project has been successful in supplying low-carbon heating to 350 high-rise buildings, a college and several office buildings.
“Recovering heat from mine water below the ground within abandoned coal mines provides an exciting opportunity to generate a low-carbon secure supply of heat, benefitting people living or working in buildings on the coalfields,” said Gareth Farr, head of heat and by-product innovation at the Coal Authority.
The water resources through the mines are estimated to be two billion cubic meters or half the amount of water in Loch Ness. Farr added, “With many millions of people living upon abandoned coalfields in Great Britain, the potential for mine water heat could be significant.”

Ben Drake, an expert on air pollution, is being interviewed on the radio. He said that smog was a severe problem in the early 20th century in Britain. At that time, Britain was experiencing a boom in industry. Factories and homes used lots of coal, which created smog. He also mentioned the heavy smog in London was particularly bad and caused over 4000 deaths in 1952. Later the UK government restricted burning coal in homes and forced factories to move away from city centers. As smog is harmful to everyone, the expert advised us to replace coal with cleaner forms of energy, use new energy-efficient vehicles and further develop green technology.
