Geothermal energy is renewable and powerful. Why is most of it untapped?

The potential of geothermal energy seems enormous. If estimates are correct, then the heat under our feet amounts to 50,000 times more power than all the oil and gas resources in the world. So why isn't everybody using this renewable energy?

This didn't give enough info on geothermal, the different types of geothermal and how it produces electricity. For people new to the subject they might assume the only type is from really deep holes in areas where the Earth's crust is so thin (so around constructive plates mostly) where its easier to get close to the heating magma, but this ignores heated rock from the decay of radioactive isotopes, which is more common to more areas around the world. Granted, the economies of scale for that type of heat extraction isn't there yet, but as the drilling equipment becomes more available due to a decline in oil drilling (same equipment, people and skills are used), then it will likely become so.

[@malikashtar7216]

Depending on the sources, Costa Rica (where I am from) produced between 19 to 22% of its electricity with geothermal energy in 2019. It is a really great way of producing electricity, it doesn't need huge centers of production, in fact they seem to be quite small. You can even find some in National Parks like the Rincón de la Vieja. They do however make a lot of noise periodically, I have often wondered how disruptive this is for nature. However, since they are quite small and don't take up a lot of space, I reckon it's worth while to pay that price. By the way, Costa Rica is the most green country energy wise after Iceland. 😀

Both Nuclear energy and Geothermal energy do the same thing boiling water to produce steam and produce electric, but most country chose building a reactor rather than drilling readily available hot spot point scattered around the world.

[@sophisticated7089]

When I think about it, it doesn’t make feasible sense or should i say “feasible capitalistic sense”. The idea of turning geothermal heat into electrical energy is not all that complex, its figuring out how to drill the holes and extract the heat in a environmentally friendly way, which we as human beings overcome more complex things before. With a capitalistic mentality i can strongly see why this area of renewable is not being explored more, its about selling an idea that is more complexed and so that will justify the high cost of such products and services. Wind and solar is quite promising but lets not forget the economics behind them both, whether its high up front cost or high maintenance cost, geothermal surpassed them on so many levels.

Geothermal doesnt work everywhere. There are a lot of limitations to this technology although it is available in many places.

I think, Geothermal is the missing puzzle piece in getting a fully renewable economy to work. Think about the most common objection to going entirely renewable (both from proponents of fossil fuels and of nucelar energy): the baseload. Geothermal can deliver the baseload, it can cover the days where there is little wind and solar. So far, as far as fostering renewable energy goes, geothermal has been ignored far to much. Also, geothermal can deliver heat for homes, wind can't (solar can, but that is really dependent and usually when solar get's much, you don't have to heat much, and when solar get's little is usually the time when you hvae to heat)

Tesla Turbines are primed to be the best turbines for direct geothermal steam electricity production! We are about to have a geothermal revolution if we actually implement these turbines!

[@lennethcruz2996]

Here in Philippines we are using geothermal energy, we are second largest next to indonesia

[@bobguerrero2986]

Now getting popular in the philippines. We have the tongonan geothermal plant. . .

[@Daniel-fl5oq]

I think it's too hard for all countries to use these new energy. Other power supply are easier

[@McSlobo]

In Finland a company drilled to depth of 6.4km (4mi) in an experiment to produce geothermal energy - without success, yet. The cost has been in excess of 100M€ so far and it will never produce enough energy to cover the cost. However, it is also an r&d project so hopefully not all the money was wasted. In e.g. Finland you can warm a house here and another there with a shallow heat wells but these heat sources will deplete if there's excessive use (i.e. dense cities). Therefore saying geothermal energy is available everywhere is a bit misleading. If more energy is poured into extracting that could be extracted then it makes no sense.

[@arshamcem8880]

This document has lots of mistakes actually , one of the main drawbacks of geothermal energy is it's not available everywhere!

[@yatarookayama8329]

5:30 Same can be said about Japan islands !

I think there is an error when DW states that Indonesia has a geothermal installed capacity of 29 GW. Data from 2022 shows that the world only has 16 GW. Probably DW meant 29 GWh/year, as the Indonesian prodcution of geothermal energy, that makes more sense with real data.

[@DWPlanetA]

Hey there! The *global electricity generation* from geothermal energy was about 16 GW in 2021. However, the global *potential* is much more (about 70-80 GW). Indonesia has a potential of 29 GW but currently only 2.3 GW installed capacity. So, one is the potential and what you mention is the current electricity generation (16GW) already happening.

the other benefit from geothermal is heating but you have to have integration in between structures with pipes for steam or water to transfer heat. not as easy as putting wires to a building but more energy efficient that having to make electricity send in through some wire then convert it back into heat. I've also wondered if they could transmit power through hydraulic line and have a generator in the building that runs from hydraulic pressure there would be a minimum of power loss from the production site? Heating and cooling are one of the biggest uses of energy. Im sure you could also use the geothermal for for cooling by making a sterling cryogenic engine where the steam would either make electricity or turbine would move the engine. you can use a sterling engine to move heat not just get mechanical energy out of heat. The other big thing that should be done is better trash collection where you have to separate plastic, glass, paper, contaminated and junk like wrap, and organic matter. use the organic matter with sewerage to make biofuels.

Great potential but still not there yet to use soon.

..if I find hotspring can I make a watt out if it ?

[@kristophxr79]

Oil will stay on top for three reasons: 1) Oil companies basically own the government. 2) Oil has a very high energy density. 3) Transportation and storage. Oil can be stored for a long time, in a very convenient form, without much need for specialized facilities.

Renewable sources of energy are always certainties. It does not ran out, Christopher, Ameriggo, Ferdinand are always beyond nourishment, not depex per minute as well. Congratulations, Kalugod-lugod at Parangal, Geothermal energy.™©®. SMEs...

[@chaos0852]

Numerous geothermal energy spots in North America, however the largest is a national park and I don’t see it being developed

[@EuroUser1]

The comparison with 'Back to the Future' is so far-fetched. Of course 1.2 GW is a lot of energy for one person to get. But it's actually just a little, for a medium-sized country.

[@jamesruscheinski8602]

Can geothermal energy units be built in basement of houses / buildings that would bring up heat from the earth below into the house / building to use for energy?

[@harukrentz435]

i dont think thats plausible because theres always risk of poisonus gas like C02 and methane released from earth.

[@QuantumNoir]

Mexico has loads of geothermal energy!💪🏼🇲🇽

[@Froggability]

Does geothermal not release unwanted heat into the atmosphere??? And as for “lasting for Millenia” even good old NZ geothermal hotspots, these sites are predict to cool down over 200 odd years etc..

[@alanaaragonzulke4431]

Is there any connection between the recent seismic activity in Iceland and the geothermal energy exploration there? I'm not knowledgeable at all sorry, just wondering!

[@DWPlanetA]

Hey Alana! During geothermal energy exploitatin, fluids are injected into the ground. They can induce seismicity and result in small earthquakes. However, we cannot tell you if the recent seismic activity is a result of that.

[@SurprisedDivingBoard-vu9rz]

Solar power grids are too much heat and blinders and melt. Maybe only in ice cold region.

[@Leptospirosi]

7:23 Italy has huge reserves of geothermal energy completely untapped: Sicily, the islands around it, the huge caldera in the Neapolitan area and several active volcanic sites, litterally the largest geothermal area outside Iceland in Europe. Japan is in the same position, preferring nuclear and oil as their general energy supply sources. Until oil will seriously rise in price there is no way serious investments will be carried on in this area, but because the less oil is demanded the less it costs... Well perspectives are not good. Keep in mind that Thorium nuclear reactors were not seriously developed because they do not produce Plutonium, so you can figure out why every nuclear plant in Russia, USA, France, UK, Israel and China is Uranium based. Electricity is just a byproduct, not the main reason for building them In 2021 only China is going to install a thorium reactor after 60+ years since it was developed, despite being much cleaner, selfshutting and Plutonium free...

[@timothyhubert2305]

Even Thorium reactors uses Plutonium

[@Leptospirosi]

Breathing Thorium reactors are technically auto sustaining regarding fuel and the amount of nuclear waste produced is so little that it can be stored for just 200 years before dropping to inert levels compared to the standard earth radiation level, while producing 2 orders of magnitude less waste then a standard uranium reactor. A "Non Breathing" reactor can use plutonium to "Fertilize" its fissile fuel, but that's a technology from the fifties no longer needed.

[@franciscoverra2307]

Phillipines have 4 geothermal plants, it contentiously operating since 1980 up to d present..

[@christopheb9221]

Does the geothermal have to be in places with geyers? I would be afraid of producing earthquakes like with fracking if you have to inject water down into the earth especially since it will turn it into steam. I guess if they put pipes in the ground and circulate water that would solve the problem but is that possible or what they do?

[@andrysuryadi]

For sure geothermal will produce earthquake for same time You can search Dutchsinse channel on youtube for earthquake detail
