Producing deep geothermal energy involves using a well, which can be several kilometres deep, to extract hot water in the aim of using its heat to generate electricity or for industrial applications. The well is drilled into what’s called a geothermal reservoir; rock containing empty space, or porosity, which allows the passage or storage of …[Read More]
