Terminology

Binary cycle power plants: these are what we could call modern plants and work using groundwater temperatures of 57 degrees centigrade or greater. The groundwater is passed through a heat exchanger that heats a liquid with a lower boiling point than water. This liquid then flash vaporizes and drives the turbines. This is what is being constructed today.

Brine: This is the hot liquid brought up by a geothermal well, it usually contains minerals and salts.
Dry steam power plants: these are the oldest and most basic geothermal power plants, they use geothermal steam that comes out of the ground at 150 degrees centigrade or greater. This steam is used to turn turbines.
Flash steam power plants: these plants make use of high pressure how water that is placed into low-pressure tanks. This results in flashed steam which then drives the turbines. They require water to be greater than 180 degrees centigrade. These types of plants are very common.
Geoexhange: This does not refer to geothermal power production, but rather to an efficient way to heat buildings using the temperature of the soil a few feet or 100 feet beneath the earth.
Geothermal power: Refers to the production of electricity using heat from hot springs or wells drilled into the earth to drive turbines that produce electricity.

Heat Exchanger: A device that takes the hot brine from the well and moves this heat to another liquid that then drives the electric turbine. 

Injection: The process of returning the geothermal fluids to the subsurface reservoir so it can be reheated and reused.

Kilowatt: 1,000 watts abbreviated as follows kW/

Reservoir: The underground natural container which holds the hot liquids.

Turbine: A rotating engine with blades that when spinning generates electricity.
