Final answer:
Iceland significantly utilizes geothermal power due to its geological location and low population, with geothermal energy providing 30% of its electricity and powering virtually all Icelandic homes.
Step-by-step explanation:
The nation that uses significant amounts of geothermal power is Iceland. This is largely due to its location on a geological hot-spot, which enables it to use geothermal energy to provide a notable portion of its electricity. In Iceland, geothermal energy accounts for 30% of its electricity production.
Iceland is a prime example of geothermal energy usage, with nearly all Icelandic homes being powered by this renewable energy source. Additionally, Iceland's low population coupled with its geological advantage allows it to utilize this resource effectively. In contrast, other nations may not have the same geothermal potential due to a lack of geological hotspots or greater energy demands that geothermal energy alone cannot meet.
