Eden Paradise switches to geothermal
The British Eden Project, a special greenhouse complex for nature and education, will have a geothermal power plant.
The plant will generate 4 megawatts green electricity and heat to the park and 4,000 households.
The plant will extract the heat deep down the greenhouse complex from geothermal – about 4.5 kilometers deep. The water is about 180 degrees Celsius, and will supply 3 to 4 megawatts of green power. The remaining geothermal heat will benefit the simulated tropical and Mediterranean climate domes in the Eden Project.
According to studies, geothermal technology could cut the average energy costs by as much as 80 percent.
Geothermal relies on the temperature differential between the ground below you and the air in your home to provide heat in the winter and cooler air in the summer.
This is how it works
If you go down a few feet, the difference in temperature between the ground and the surface on the hottest or coolest days may be 40 degrees Fahrenheit or more.
- With heat-absorbing water circulating continuously through a geothermal system’s network of pipework, the heating and cooling potential of this differential can be efficiently and consistently harvested.
- Geothermal systems do use a significant quantity of underground polyethylene piping. However, these pipes can be installed vertically not just horizontally. A medium-sized patches of lawn may be sufficient.
- Geothermal heating and cooling systems are quiet, don’t use refrigerants (only water) and feature underground piping networks that can last indefinitely
- The indoor air compressors and air handlers can last for a couple of decades if properly maintained.

The distinctive domes have been used for the James Bond Movie ‘Die Another Day‘ (2012).
Nowadays, more than a thousand different plants an animals are living in the two large transparent domes.
In one dome is a tropical climate simulated, the other accommodates Mediterranean species. Both biomes consume a lot of energy, especially in the form of heat.
This warm tropical climate requires a lot of water. Therefore the Eden Project uses only rainwater.
