Texas

you can find geothermal energy anywhere in the state

Especialy in East Texas (DFW area)

Geothermal and hot water and steam (hydrothermal) are used as heat sources. They can be used to warm houses and businesses.

Energy Availability

These hydrothermal hot spots don’t occur everywhere. In the U.S. they are located in the Western States, Alaska, and Hawaii.

Geothermal power is primarily available where hot magma finds its way close to the surface and heats ground water to usable temperatures above 212F.

Energy Reliability

They require no purchase or transport of fuel. They require no waste disposal.

geothermal plants may be the most reliable of all energy production methods. Since they are fundamentally simpler than most other power systems, there is less to go wrong.

They have no intermittency or dispatchability problems.

Main topic

Environmental Friendliness

Pros

Geothermal facilities have no coal or nuclear fuel to mine and transport, no radioactive wastes or ash wastes to deal with, and no emissions of carbon dioxide, particulates, or other combustion byproducts.

Compared to Coal as a resource

Cons

A few Geothermal facilities produce some silica and sulfur dioxide, both of which are largely removed from the vapors and either returned to the hydrothermal well.
