Settlements near geothermal reservoirs began to experience seasonal thaws.

In the United States, most geothermal reservoirs of hot water are located in the western states, Alaska, and Hawaii.

When correlated with current weather conditions, this can be measured and modeled to estimate the rate of recharge in geothermal reservoirs.

This water will be naturally heated in the geothermal reservoir, and be captured by the existing power plants as steam.

The geothermal reservoir at Spring Hill was discovered on 2 June 2008.

Lake Naivasha underground water may be feeding the geothermal reservoir at Olkaria, which has caused concern since the lake has been shrinking in size recently.

In order to extract geothermal energy, it is necessary to efficiently transfer heat from a geothermal reservoir to a power plant, where electrical energy is converted from heat.

Two springs at Olene Gap are actually warm artesian springs whose waters are partly derived from the geothermal reservoir.

Geothermal power is generated by using steam from geothermal reservoirs to drive turbines and generators.

Places such as the Philippines, Hawaii, Alaska, Iceland, California, and Nevada have geothermal reservoirs closer to the Earth's surface, making its production cost-effective.
