Energy 101: Geothermal Energy

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.

whos watching for school work lol

Wow can't believe this was a entire year ago

[karinaplays]

The fact that he explained this for 3 minutes and my teacher explained this for 1 week

The basketball hoop at 1:07
Seems like a fun workplace

[thangsang]

Some time the best way to explain is to put everything in simple everyday vocab and not scientific

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.

This is a great addition to the Energy 101 playlist, which does a good job of sharing fundamentals. Could be used as a nice "warm-up" to start a science class.

Is that a basketball hoop in the lab at 1:07 😂

[nekokaru]

Thanks a lot! Very simple yet informative. Took me 3mins to learn 1 week's worth of lesson.

[rabidapocalypse]

Tried looking for a video on Geothermal Energy for a power point presentation. Couldn't be any more perfect than this.

[justkiddingwithahmad]

Video was great and and instructive. when you use the word "flashing", it means technically, that it evaporates abruptly because of pressure lower than its saturation pressure, which isn't what happens in heat exchangers. You'd rather use evaporation.

“…Growing energy demands.” What an understatement.

[jackbowersox]

this video made me feel at home. thank you department of energy

[seraph]

Thanks Italy for introducing this Energy 😍👍

[-gi]

Thanks for your explanation and teaching and thanks again

[thebrinksf]

But does it work night and day year round without the use of fossil fuels?

[sparkeyjones]

Woah! I'm the one millionth viewer! What's the prize?

[dr.lukasf.olsnes-lea]

FYI: there are 2 ways of geothermal energy. 1 is the way you show, to use the natural sources of hot water. 2, however, involves drilling a hole and inserting 2 pipes connected at the bottom and lowered by a metal wire and continuously extended by adding pipes much like oil drilling. In the end the 2 pipes are long enough to lead water down and hot water up so to exploit this for geothermal energy also. Thus, geothermal energy is now available, cheaply, to all people on Earth. Remember to insert fluids to secure good contact for the warm hole so that water becomes hot quickly to ensure LOTS of geothermal energy return! Best wishes.

This helped me with my assignment. Thanks to the US Department of Energy.

[grcgeothermalresourcecounc]

An excellent video on the one clean, dependable renewable energy.

Well done D of E!

camera man at the beginning talking about relaxing
Kid: *frontflips*

yeah thats top tier relaxation
