Why It's So Hard to Exploit Geothermal Energy
By Bloomberg Originals
Key Concepts:
- Geothermal Power: Clean energy derived from the Earth's internal heat.
- Geographic Limitations: The specific geological conditions required for traditional geothermal energy extraction.
- Startups & Innovation: New solutions being developed to overcome geographic limitations and expand geothermal power's reach.
- Risks of Geothermal Energy: Potential negative consequences associated with increased geothermal energy development.
Main Points:
The video focuses on geothermal power as a clean energy source beyond solar and wind, highlighting its potential and current limitations. While geothermal energy is utilized in countries like Iceland and New Zealand, it only contributes 0.3% to global electricity needs.
Geographic Limitations:
Traditional geothermal energy extraction requires a specific combination of three geological conditions:
- Heat: A source of high underground temperature.
- Water Reservoir: A significant body of water to be heated.
- Porous Rock Layer: A layer of rock with sufficient permeability to allow water flow. The rock layer needs to be full of holes so water can flow through the super hot rock.
The video emphasizes that achieving this "tough trio" of conditions is a major obstacle to wider geothermal adoption.
Startups and Innovation:
The video mentions that startups are actively developing innovative solutions to overcome these geographic limitations and make geothermal energy more accessible in diverse locations.
Risks of Geothermal Energy:
The video concludes by raising the question of potential risks associated with increased geothermal energy development, suggesting that further exploration of this topic is available in the "Primer" show on Bloomberg Originals.
Conclusion:
The video presents geothermal power as a promising but currently underutilized clean energy source. Its potential is limited by specific geographic requirements, but ongoing innovation by startups offers hope for broader adoption. The video also hints at potential risks that warrant further investigation.
