Geothermal is a lesser-known type of renewable energy that uses heat from the Earth’s molten core to generate electricity.

While this unique feature gives it major advantages over solar and wind, it also suffers from high costs and geographic limitations. Because of this, few countries have been able to produce geothermal energy at scale.

In this infographic, we’ve used a combination of diagrams and charts to give you a high-level overview of this sustainable energy source.

Geothermal energy is produced by accessing reservoirs of hot water located several kilometers below the earth’s surface. In some parts of the Earth, this water naturally erupts through the surface, creating what is known as a hot spring (or in some cases, a geyser).

When accessed through a well, this pressurized water rises and rapidly expands into steam. This steam is used to turn a turbine, which drives an electric generator.

Later in the process, excess steam is condensed back into water as it passes through a cooling tower. An injection well pumps this water back into the earth to ensure sustainability.

What Is The Carbon Footprint Of Geothermal Energy? A Life Cycle Assessment

As of 2021, global geothermal electricity production totaled 16 gigawatts (GW). Only a handful of countries have passed the 1GW milestone.

While geothermal plants produce less electricity, they have advantages over other types of renewable energy. For example, geothermal energy is not affected by day-night cycles, weather conditions or seasons.

We now look at a second data set, which shows the global contribution of each type of renewable energy. These data are as of April 2022, and are sourced from the International Renewable Energy Agency (IRNA).

*The total Geothermal capacity in this data set is different from the previous value of 16GW. This is due to various sources and rounding.

A Visual Crash Course On Geothermal Energy

One of the reasons for the slow adoption of geothermal energy is that it can only be built in areas with suitable geological characteristics (such as places where there is volcanic activity).

To expand on this point, consider the following data from Fitch Solutions, which shows the projected growth of geothermal energy capacity by region.

Fitch believes that over the next decade, the majority of new geothermal capacity will be installed in Asia. On the other hand, investments in North America and Western Europe (NAWE) are expected to decline.

Over the next few years, NAWE will experience a gradual slowdown in geothermal capacity additions as we expect investment to be crowded out by cheaper wind and solar projects. – Fitch Solutions

The leading markets for geothermal are expected to be Indonesia, the Philippines and New Zealand, all of which lie along the Pacific Ring of Fire. The Ring of Fire is a path along the Pacific Ocean where most of the volcanic activity occurs.

In 2022, 29, 165.2 terawatt hours (TWh) of electricity were produced worldwide, an increase of 2.3% from the previous year.

In this visualization, we look at data from the latest Statistical Review of World Energy, and ask what’s driving the world in 2022.

Coal still leads the charge when it comes to electricity, accounting for 35.4% of global electricity generation in 2022, followed by natural gas at 22.7%, and hydroelectric at 14.9%.

Over three quarters of the total electricity produced by coal in the world is consumed in only three countries. China is the leading user of coal, accounting for 53.3% of global coal demand, followed by India at 13.6%, and the US at 8.9%.

Berlin’s Green Shift: Turning Up The Heat With Geothermal Energy

Burning coal – for electricity, as well as metals and cement production – is the world’s single largest source of CO2 emissions. However, its use in electricity production has actually increased by 91.2% since 1997, the year the first global climate agreement was signed in Kyoto, Japan.

In 2022, renewable energy, such as wind, solar and geothermal, accounted for 14.4% of total electricity generation with an extraordinary annual growth rate of 14.7%, driven by large gains in solar and wind. Non-regenerators, on the other hand, made only 0.4% anemic.

The authors of the Statistical Review do not include hydroelectricity in their renewable calculations, although many others, including the International Energy Agency, consider it an “established renewable electricity technology.”

With the transfer of hydroelectricity to the renewable column, they together accounted for more than 29.3% of all electricity generated in 2022, with an annual growth rate of 7.4%.

In addition to disruptions at the Zaporizhia nuclear power plant in Ukraine, shutdowns in France’s nuclear fleet to address corrosion found in the safety injection systems of four reactors led to a 4% drop in global use, year-on-year.

The amount of electricity produced from nuclear energy in that country has decreased by 22% to 294.7 TWh in 2022. As a result, France has gone from being the world’s largest electricity exporter to a net importer.

Converting mechanical energy into electrical energy is a relatively simple process. Modern power plants are engineering marvels, no doubt, but they still work on the same principle as the very first generator invented by Michael Faraday in 1831.

But the way you get the mechanical energy is where things get complicated: coal powered the first industrial revolution, but warmed the planet in the process; The spirit is free and pure, but not reliable; And nuclear fission reliably produces electricity without emissions, but also creates radioactive waste.

One such energy source is shallow geothermal energy and it deserves more attention. It is an almost unlimited source of energy-efficient heating and cooling that can be used by any building, regardless of its purpose.

Shallow geothermal energy is one of the most convenient renewable energy sources, which exists almost everywhere in Europe.

How Do Geothermal Heat Pumps Work

Shallow geothermal energy is essentially the heat of the earth’s crust – from a depth of 1.5 meters to a depth of 300 or 400 meters. The heat originates in the earth’s core and is therefore the cleanest and most inexhaustible source of energy.

The use of shallow geothermal energy relies on the constant temperature of the Earth’s crust. It doesn’t matter if it’s a freezing winter or a hot summer outside, a broad layer of the Earth’s crust always has a temperature of around 13 degrees Celsius. You must have noticed this phenomenon when you went to a cellar or a cave – in the summer it is pleasantly cold and warmer than you would expect in the winter. This layer of constant temperature starts at around 3 meters depth. If we go deeper, the earth gradually warms up and reaches 20 to 25 degrees Celsius at a depth of 400 meters.

This difference between the outside temperature and the temperature of the Earth’s crust is exploited by shallow geothermal systems. These systems, very simply, “extract” the heat from the ground in the winter and return cold to it, and vice versa in the summer. Don’t worry, we’ll talk more about it soon.

Shallow geothermal systems do not produce carbon dioxide emissions. This means that over the course of a year an average residence reduces enough carbon emissions to be equivalent to taking two cars off the road. The effect is even greater when it comes to larger buildings.

What Is Shallow Geothermal Energy And Why Should You Use It?

Shallow geothermal energy does not depend on the sun, wind or weather conditions and is available all year round. This is a huge advantage, as reliability is a burning issue when it comes to using other renewable sources, such as solar or wind. Shallow geothermal systems are also safe, as there is no risk of a carbon monoxide leak or explosion.

Although shallow geothermal energy is usually associated with heating, hybrid systems make good use of it for both heating and cooling. This results in significant savings throughout the year.

Shallow geothermal heat pumps and hybrid systems typically use 25% to 50% less electricity than most conventional heating and cooling systems. Not only that, their hardware is quite small, so they
