What Is The History Of Geothermal Energy – Geothermal energy has been around since the Earth was formed about 4.6 billion years ago. This thermal energy generated and stored by the Earth has been used in many different ways throughout history. This article examines the history of geothermal energy from its first use by mankind to modern times.
Thermal energy generated by the Earth has been used since the Paleolithic period when it is believed that hot springs were first used for bathing. This primitive use of geothermal energy was later developed further by the Romans in the first century AD.

What Is The History Of Geothermal Energy
It was not until 1904 that there was a breakthrough in using geothermal energy as an energy source. On day 4
Geothermal Power In Japan
In July 1904 at the Larderello dry steam mine in Italy, Piero Ginori Conti tested the first geothermal generator. This small generator can provide enough power to light five light bulbs.
Piero Ginori Conti would further develop his technology to build the first geothermal power plant that opened in 1911 in the Valle del Diavolo (“Devil’s Valley”) in Larderello, Italy. This ‘dry steam’ geothermal power station would supply electricity to the Italian railway system and would remain the only geothermal power station in the world until 1922.
In 1922 in the United States, John D. Grant would inaugurate the world’s second geothermal power plant. It can produce 250 kilowatts of electricity and is used to power street lights and buildings in the local area. Unfortunately, this power plant is not highly competitive with other energy sources and will close soon after.
In 1958, New Zealand’s Wairakei Power Station went into operation, becoming the second largest industrial geothermal power producer in the world. This power station will be the first in the world to use ‘fast steam’ technology. You can learn more about the different types of geothermal power plants here.

The United States finally achieved success with geothermal power generation in the 1960s when the first large-scale geothermal power plant became operational, producing 11 megawatts (MW) of electricity. This is considered a huge victory for the United States and will pave the way for a new generation of geothermal power plants in the country.
In the coming decades, other countries including Iceland, Kenya, Indonesia, the Philippines and Mexico will invest in geothermal energy technology.
Today, the largest producer of geothermal power is the United States, which had an estimated total installed capacity in 2013 of just under 3,400 MW.
In recent years, Indonesia has surpassed the Philippines to become the world’s second largest geothermal power producer. Italy is currently the fourth largest geothermal power producer and New Zealand is fifth.
What Is Geothermal Energy? Definition And How It Works
Although there are geographical limitations to using the full potential of geothermal energy technology, we will likely see more powerful, more efficient geothermal power plants built in the future. next decade.
The use of geothermal energy, along with solar, wind and hydropower, can help pave the way to a brighter future by reducing our dependence on depleting non-renewable energy sources. generated like coal, oil and gas.

Describing how geothermal heating and cooling systems work can make it sound like science fiction. After all, you would think that there would need to be some kind of futuristic technology to harness renewable thermal energy underground to heat and cool homes with 300-600% efficiency.
Humans have used the principles behind geothermal for centuries, and the basic technology that powers geothermal heating and cooling systems, or ground source heat pumps, has existed since the late 1940.
Geothermal Power’s Competitive Landscape
In fact, Western and Northern European countries have converted a series of homes to using geothermal heating and cooling systems since the 1970s. In 1980 alone, Germany installed nearly 25,000 home heating systems. geothermal heating and today one in five homes in Sweden is heated by a ground-source heat pump. In the US, a recent study by the Department of Energy found that up to 28 million American homeowners would save a lot on heating and cooling costs if they upgraded to geothermal today.
To really understand why, you need to review the entire history of heat pumps, but the short answer is cost. Installing a geothermal system is a major investment, and while it can save most homeowners thousands of dollars in the long run, it has traditionally come with a price tag. quite high before. Fortunately, Dandelion’s innovative technology, business model, and financial tools are “disrupting the geothermal energy space,” making it more affordable and accessible to homeowners. ever. To find out how Dandelion changed the status quo, let’s zoom out and look at the historical context of geothermal home heating and cooling.
Archaeological evidence shows that humans have been harnessing thermal energy more than 10,000 years ago. Early humans must have understood the fact that the earth kept a constant temperature all year round because, as their name “cavemen” suggests, they used underground caves to stay cool in warm weather. Warm and warm in cold climates. Archaeologists have noted that cave living persisted from prehistoric times to the ancient world when people in places as disparate as New Mexico and ancient Turkey developed ‘cave cities’. large movements to maintain comfort and store food at a stable temperature.
In (slightly) more modern times, Bavaria’s original beer gardens kept their beer tanks cool by storing ice year-round in underground tunnels. Even after refrigeration put an end to the use of ice cellars, brewers still used deep cellars to keep their beer at a stable temperature. Nearly two hundred years ago, America’s oldest brewery, Yuengling in Pennsylvania, hired nearby coal miners to dig “beer caves” that stored freshly brewed beer underground at temperatures of about 50 degrees during the winter. during hot summers and cold winters. Those “beer caves” are still in use today!
Geothermal Everywhere: A New Path For American Renewable Energy Leadership
The first theoretical applications of geothermal as we know it today appeared at the height of the Scientific Revolution. In the mid-18th century, Scottish physician William Cullen used pumps to demonstrate the possibility of artificial refrigeration. A century later, British engineer Lord Kelvin used that innovation to hypothesize that the refrigeration process could work in reverse and coined the concept of the modern heat pump. A few years later, in 1857, Austrian Peter von Rittinger developed the first operating heat pump and in 1912, Mexican-Swiss engineer Heinrich Zoelly filed the first patent for a geothermal heat pump or land source in Switzerland.
The earliest “geothermal” heating systems may be more accurately called “hydrothermal” because they used river water as a heat source. In the 1930s, the Zurich town hall building harnessed thermal energy from water flowing in the Limmat River to provide heating and cooling. Because river water temperatures fluctuate and can even freeze, the limitations of the technology are quite obvious. It wasn’t until the 1940s that American scientist Carl Nielsen of Ohio State University developed the first true ground source heat pump for use in his own home.
Nielsen’s ground source heat pumps still use water, but his system captures heat energy from groundwater where the temperature is stable. By tapping into a stable, renewable underground heat source, Nielsen’s system can keep his home comfortable with year-round heating and cooling. Across the country, researchers have built on these developments, and in Oregon, the first commercial geothermal system was developed to provide space conditioning for a 14-story downtown building. Portland Street in 1946. Like Nielsen’s home heating system, Portland’s geothermal system uses groundwater as its heat source. Today we call it an “open loop” geothermal system, we will talk a little more about the ground loop later.
Under the most favorable circumstances, “hydrothermal” experiments in Zurich in the 1930s resulted in space heating and cooling efficiencies of over 200%. Not bad for a technology that was introduced at a time when people still burned coal and sawdust to keep warm. Better yet, American geothermal systems of the 1940s boasted operating efficiencies of over 400%. Although the core principles of geothermal technology have not changed much since then, further innovations in installation will make ground source heat pumps even more efficient, affordable and more accessible to everyday homeowners.
Project To Pour Water Into Volcano To Make Power
America’s postwar boom was fueled by cheap fossil fuels. In 1964, you could fill up your family’s Ford Galaxie for as little as $0.30 a gallon. The same principle applies to home heating: coal and sawdust have given way to fuel oil, which is cheaper than ever, while more and more homes are equipped with gas systems. Naturally cleaner and more effective. That all changed in the 1970s, when oil-producing Arab countries limited global fuel supplies in response to the Yom Kippur War that caused the “oil shock” of 1973 and 1979. overnight, fossil fuel prices skyrocketed, causing the US and European economies to fall into deep recession. One of the consequences of the oil crisis of the 1970s was a rethinking of technologies
