See how we can generate clean, renewable energy from hot water sources deep beneath the Earth’s surface. The video highlights the basic principles at work in geothermal energy production, and illustrates three different ways the Earth’s heat can be converted into electricity.

About this video. It's a good video, but has some errors. Just so you know: (1) Dry steam plants are not the "most common type" of geothermal plants in or U.S. or in the world. Flash plants are the most common in the world, dry steam fields are rare, but large, providing steam to numerous plants each. (2) In flash plants, the "fluid" (hot water and steam from underground) that is described in this video can either rise forcefully up wells under it's own power, or be pumped up the well. (3) Cooling of the hot geothermal water does not cause it to flash to steam. Rather, the very hot (over boiling) geothermal water remains as mostly water underground because of the high pressures deep underground. Being released from the high pressures at the surface is what causes it to flash. Cooling it actually causes it to revert to water and contract (as is what happens at the back of the turbine, where it passes through a condenser unit. Flashing is an expansion and the pressure of the expansion is what drives the turbine blades. (4) In the geothermal industry, the "heat transfer fluid" used in binary geothermal power plants is more commonly called the "working fluid." You can look up the definitions of both terms to understand why working fluid is the better term for binary geothermal plants.
10%??? More like 80-90% of our needs. Geothermal can run whole cities and should replace nuke plants immediately.

What is the song/instrumental in the video?
+U.S. Department of Energy Wow parece ser bem promissor 🙂 Mais isso não poderia resfriar o núcleo da Terra a longo prazo?
one of the best natural power source..
I didn't know turbans could be spun…
The reservoir would have to be 12,877 feet (2.4 miles) underground, in order for the water to be just hot enough to boil.
thanks that's good to know
This sounds like Jason Silva O.o
sup fgts
Is that a basketball hoop in the lab at 1:07 😂
That is good
Tried looking for a video on Geothermal Energy for a power point presentation. Couldn't be any more perfect than this.
Nice
There is no disadvantage to geothermal energy.
this was really helpfull thanks
wow, this was really helpful, and awesome. Thank you!!
There is a basketball hoop between 1:06 and 1:07.
I looked this up for my science fair
Con…High water usage, due to evaporation?
Is there a reason you say, "virtually" limitless supply? You mean we will run out in a billion years?
In Iceland, you seem unconcerned with H2S gas. Why?
the intro to this video make s me want to stab you…
Great job
wat is the difents in geo thermal & pasitive wat is cheper witch is batter
Thanks for helping me with my project Mr. Lubbers!
XOXOXOXO
GG
by product…?
why water is cooled before sending back?
YOU ARE SO COOL
Great. Helped me with homework. Excessive use of noises. Don't watch if you faint at flashing lights.
Here is the rest of the answer The largest power station by far is Kárahnjúkar Hydropower Plant (690 MW), which generates electricity in the area north of Vatnajökull for the production of aluminum.
Other projects and stations include:
Blöndustöð generates 150 MW
Búrfellsstöð generates 270 MW
Hrauneyjafosstöð generates 210 MW
Laxárstöðvar, on the Laxá River, generates 28 MW
Sigöldustöð generates 150 MW
Sogsstöðvar generates 89 MW
Sultartangastöð generates 120 MW
Vatnsfellsstöð generates 90 MW

most of icelands electricity comes from hydropower not from geothermal. 90% of hot water comes from geothermal, which produces about 30 % of electricity needs
Sound Quality very bad
nice video
very awesome video
Your wrong
Cool
its not effects its wind
