So we see it as a really meaningful contributor to our technology tool kit...."

> The developments Thursday come as [4]tech companies race to find new sources of zero-emission power for data centers that can use as much energy as entire cities. With major backing from Google parent Alphabet, Fervo recently got its first project up and running in the northern Nevada desert... The advanced geothermal technology that Fervo is trying to scale up is an attractive option for tech firms. Enhanced geothermal plants do not pose all the safety concerns that come with nuclear power, but they have the potential to provide the round-the-clock energy that data centers need. The challenge Fervo faces is whether it can bring this technology online quickly enough.
Fervo (a seven-year-old start-up) was co-founded by Tim Latimer, who previously worked as a drilling engineer, according to the article. But "Early in my career I got passionate about climate change. I started looking at where could a drilling engineer from the oil and gas industry make a difference," Latimer said during [5]a Washington Post Live event in September. "And I realized that geothermal had been so overlooked ... even though the primary technical challenge to making geothermal work is dropping drilling costs."

Geothermal energy, has downsides. In open systems, it generally produces significant excess heat that gets pumped into the surrounding environment, i.e. hot water dumped into streams and rivers, then unsurprisingly, algae blooms, and native species die out. Closed systems don't have the same problem, but since they are more expensive, are not always/often used.
Their is a cost to the environment.
You can't dump an infinite amount of heat energy into the environment without consquences.

I'm a bit lazy to do so. However, I'll explain. I did some market research for a US geothermal company sitting on 5 patents for a closed system, around 15 year ago now.
My personal takeaways were thus. Open systems always lose efficiency over a number of years.. bascially the pressure inside the open system drops and the electricity outputs therefore also drop over a period of time. So the "answer" was to create closed systems, ie. put stuff in tubes, then circulate the stuff, almost exactly like a heat pump

That's not quite true. Either there's an infinite amount of human stupidity, or we can harness energy from Albert Einstein spinning in his grave.

You’re not wrong, of course, but problems with waste heat are hardly limited to geothermal power - any power plant using heat transfer has similar issues to a greater or lesser degree, including coal, oil, natural gas, and nuclear. Even solar power systems that rely on solar energy to heat up a furnace will have to get rid of the heat somehow.
Geothermal also has the potential for producing waste water contaminated with sulphur, metals, or other pollutants that get brought up with the heat transfer

That's 1kW per home. That might be a valid number if people haven't converted from gas heating/hot water/clothes drying/cooking.
Re: (Score:2)
Yeah, that seems low, but they're probably thinking mostly apartments/small homes. Still, 1kWh average is a lot. If your electricity+delivery cost was 12 cents per kWh, your bill would have to be upward of $88+fees (most likely around $200) if you used an average of 1kW/hour. But most people who live in apartments' cost is less than $200
Now that I've put my usage in numbers, I'm really wondering what I'm doing that's using 3.5kWh/hour. I guess it's time to get back to my panel sensor project ...

I believe you don't really understand the scale of the planet.
The Earth is quite large. Much of the heating in the core is from the decay of heavy elements buried in very deep. Maybe we end up poking in a few holes that lower the resistance of this heat escaping into space but that's not likely to make any changes that are detectable beyond the local area.

If the Earth's mantel cools to the point that we can't extract usable energy from it anymore, I propose there would be FAR bigger concerns than keeping the power plant open for business.

The answer to the question on if geothermal power is able to revolutionize the energy supply the answer is not likely.
There's been many people that did the math on what every energy source we know of consumes in resources and provides in useful energy. Geothermal does not rank well. The problem is that the power production is too diffuse. The global average on geothermal power has been approximated as 0.1 watt per square meter.

Nothing wrong with full employment, but the cost of geothermal is not competitive with wind or solar. I guess the same could be said for nuclear power and the need to keep those workers employed.
