As dry as Nevada may seem, there is still considerable water in the rock below, recharging the reservoirs of water that exist in the stone, like water in a sponge. Injection wells force the now-hot water to find an outlet — the intake well. Geothermal fluids (hot water) are brought to the surface through production wells, some as deep as 2 1/2 miles. The steam drives turbines in the power plant.
