Large-scale geothermal energy production could reduce global warming, provide clean energy where needed, and improve people's lives across the world.

Summary

The earth's core is the same temperature as the sun-6000 degrees C. Fortunately the earth's crust insulates us. However, we could utilise this Green geothermal energy. Key points are: 
  • It is already in use, i.e. Iceland.
  • It could be available relatively easily to access across the world.
  • A potentially disruptive technology that several tech startups are already researching.
  • Could provide energy where needed, reduce the impact of climate change and help developing nations by providing power to many more people.
  • Thermal energy needs hot, porous rocks and water.
  • A variety of different extractions methods are being used.
  • One method is to use a closed-loop system that is similar to a radiator.
  • Existing oil drilling technology could be repurposed to produce geothermal energy.
  • Incremental improvements are standard practice in oil drilling.
  • Directional oil drilling technology reduces environmental impacts.
  • Oil companies are already funding geothermal technology.
  • Provides an opportunity for oil companies to become environmentally friendly.
