Geothermal Energy Overview

A set of flashcards covering key concepts about geothermal energy, its advantages and disadvantages, and its applications.

Geothermal Energy

The heat from the Earth, which is clean and sustainable.

Renewable Energy Source

Energy that is continuously produced, such as heat from inside the Earth.

Geothermal Power Plant

A facility that generates electricity by using heat from deep inside the Earth to produce steam.

Geothermal Heat Pumps

Systems that capture heat close to the Earth's surface for heating and cooling buildings.

Conventional Geothermal System

Utilizes steam from natural sources like geysers or high-pressure hot water from deep Earth.

Supercritical Geothermal System

Uses steam or heat from supercritical fluids, with higher energy than conventional systems.

Dry Steam Power Plant

The oldest geothermal technology that directly uses steam to drive a turbine.

Flash Cycle Steam

A power generation method that converts hot water to steam to drive a turbine.

Binary Cycle Power Plant

Uses a secondary liquid with a lower boiling point to produce electricity from geothermal energy.

Advantages of Geothermal Energy

Includes being renewable, environmentally friendly, reliable, having a long lifespan, versatile applications, and providing economic benefits.

Disadvantages of Geothermal Energy

Includes location limitations, high initial costs, potential resource depletion, environmental concerns, risk of induced seismicity, and water usage.

Geothermal Energy in the Philippines

Philippines ranks 3rd globally in geothermal energy production, contributing 12% of the nation's energy needs.
