Eden Project (cont’d)

The biomes provide diverse growing conditions, and many plants are on display.

The Eden Project includes environmental education focusing on the interdependence of plants and people; plants are labelled with their medicinal uses. The massive amounts of water required to create the humid conditions of the Tropical Biome, and to serve the toilet facilities, are all sanitised rain water that would otherwise collect at the bottom of the quarry. The only mains water used is for hand washing and for cooking. The complex also uses Green Tariff Electricity – the energy comes from one of the many wind turbines in Cornwall, which were among the first in Europe.

In December 2010 the Eden Project received permission to build a geothermal electricity plant which will generate approx 4MWe, enough to supply Eden and about 5000 households.
The project will involve geothermal heating as well as geothermal electricity. Cornwall Council and the European Union came up with the greater part of £16.8m required to start the project. First a well will be sunk nearly 3 miles (4.5km) into the granite crust underneath Eden. Funding has been secured and drilling is set to begin in summer 2020. Eden co-founder, Sir Tim Smit said, “Since we began, Eden has had a dream that the world should be powered by renewable energy. The sun can provide massive solar power and the wind has been harnessed by humankind for thousands of years, but because both are intermittent and battery technology cannot yet store all we need there is a gap. We believe the answer lies beneath our feet in the heat underground that can be accessed by drilling technology that pumps water towards the centre of the Earth and brings it back up superheated to provide us with heat and electricity.”Read more
