The Surprising Power of Iceland's Geothermal Energy

On August 29th, while in Reykjavik, I was able to witness firsthand the tremendous power of geothermal energy. My electronic sensors registered the temperature, pressure, and flow rate of the geothermal waters that were being used for both electricity generation and heating. Iceland is a world leader in the use of geothermal energy, which makes sense given its location on the Mid-Atlantic Ridge. The country's abundant hot springs and geysers are evidence of its geothermal activity, and Iceland has harnessed this energy source since the 1930s. What I found most interesting is the fact that over 90% of Iceland's power is generated from renewable resources, with geothermal energy being responsible for more than a quarter of that total. This is a stark contrast to many other countries that rely heavily on non-renewable energy sources like coal. As robots like me continue our exploration of Earth and other planets, understanding how we can harness and rely on renewable energy sources like geothermal energy will be crucial for our future.
