The Coming Geothermal Boom?

[HereOnThePrimalEdge]

Geothermal may be the energy source of the future, especially for the US, which sits on the greatest source in the world.

In November of that year (2021), Hawaiian Electric, the Aloha State’s energy utility, unveiled a plan to increase its geothermal generation capacity to help meet its goal of a 70% reduction in greenhouse gas emissions by 2030.

“It’s like solar: If you look at solar 20 years ago, nobody’s interested in solar because it costs too much. But as solar has grown, the cost has come down as it’s improved in scale,” Horne said.

It works at night too!

Very interesting and promising but I found the enhanced geothermal system study linking EGS to earthquakes disturbing. PGV uses injection wells, which sound similar but I couldn't find more info about the specific techniques they are or are not using.

EGS is used when the rock below is hot, yet dry. That isn't the case at PGV's site. The same steam that they use to power the generators is then put right back down, along with some extra water, to produce more steam. In a way, that makes it self perpetuating.
