Geothermal energy used to heat Eden Project

Bosses said it was expected the technology would save up to 500 tonnes of carbon dioxide per year

The Eden Project's biomes, offices and plant nursery were heated by deep geothermal energy during the winter, the attraction has revealed.

A 5km (3.1m) well located on the site started to generate heat in June 2023 and started to supply heat for the first time as the weather become colder.

Bosses said it was expected the technology would save up to 500 tonnes of carbon dioxide per year and take the attraction almost entirely off gas.

The Eden Project's chief transformation officer Si Bellamy OBE said it "will help us accelerate massively our mission towards a climate-positive future.”

He added: “We are working with and for nature to develop new ways to grow and new ways to encourage people to think differently about plants, the planet and themselves.

“We have built a landmark sustainable nursery and education facility - a pillar of our wider ambitions for the future impact and expansion of the Eden Project."
