What happened

Harnessing the power of just one per cent of superhot rocks could provide more than eight times the current global electricity generation.

Why it matters

Deep beneath the Earth’s surface lies an immense source of energy that scientists believe could help power a low-carbon future.

Common ground

A growing number of researchers and energy companies are now racing to unlock ‘superhot’ geothermal energy, a very old – but also novel – form of power that could provide constant, carbon-free electricity almost anywhere on Earth.

Perspective signals

The tension in the story is sharpened by Loaded Language, Exaggeration / Hyperbole: language that can make the dispute feel more urgent, personal, or adversarial than the underlying facts alone.
