A volcano erupts, and lava spews everywhere, burning every living thing it touches. By the time the eruption is over, not a single blade of grass is still living in the area. Volcanoes and their magma have always been viewed as chaotic, uncontrollable objects. But what if humans could use them for their own advantage?
Geothermal energy is energy from Earth’s heat. Geothermal energy has some advantages over other types of energy. One is that it is available over 90% of the time compared to coal plants only getting 75%. That means that while many power plants, like solar plants and wind turbines, and even coal plants can’t be producing energy anywhere near all of the time, geothermal energy plants can be working nearly all of the time. Recently, scientists drilling into the Krafla volcano in Ireland, led by Gumunder Omar Friedleifsson accidentally discovered that magma can be a useful way to get geothermal energy. This happened when the scientists found magma 7,000 feet into the earth. They soon realized that the water heating the drill they were using, and the extremely hot magma made a superheated steam tha could be chemically altered to power a turbine. After the discovery, scientists estimated that geothermal energy from magma could produce 25 MW of power, which is 5 times more than current geothermal energy wells makeInterestingly enough, this more powerful energy would also be cheaper, because conventional geothermal energy needs expensive perforated piping down the entire hole, while geothermal energy from magma would only need it for about 100 meters. Also, unlike fossil fuels, another cheap energy source, geothermal energy is renewable, and it does not harm the environment a lot. This one accidental discovery the scient...

...many of the island country's economies, because they wouldn’t have to import a lot of fossil fuels for their energy. This would help the whole world in general, and could keep them from going any farther into debt. Geothermal energy from magma will be extremely useful, especially to countries with a lot of volcanoes that are in debt.
Scientists have discovered that magma can be used to make geothermal energy. This would be very useful, as it is much more efficient than conventional geothermal energy, and it is better for the environment than fossil fuels, and it is renewable. There are, however, some bad parts about the energy. The plants could cause minor earthquakes, and could be destroyed by the volcano erupting. However, the advantages of geothermal energy from magma outweigh the risks, and it probably will become a very important energy type in the near future.
Hawaii’s geography is optimal to make use of biofuel, solar, and geothermal resources (Brown et al. 2008, 27). The focus of this paper will concentrate on three alternative energy solutions: 1. Biofuels, 2. Solar Power, and 3. Geothermal. Biofuels will be broken down into biomass, ethanol and biodiesel. Solar energy will be divided into solar power plants, residential solar and passive solar systems. Geothermal energy is constituted of geothermal power plants, geothermal water heating and heat pumps.
A big question in today's world is to or not to live by it will Volcano. Volcano's are very dangerous it can cause lots of damage not only in things that humans too. Irruptions can be unexpected and destroy a whole city! I think people shouldn't live by a volcano because it's very dangerous and if it's in the ring of fire.
A super volcano is different to a normal volcano. The physicality maybe similar, but instead of one blast, they are a series of separate eruptions which then converge into one mega eruption. Each is a result of rising and growing chamber of hot molten rock known as magma. The problem is volcanoes are split into three categories: active, dormant and extinct. For scientists, active volcanoes are less of a threat as scientists know when they will erupt. With dormant however, they are scientist’s worst fear as they can come back to life and erupt. Volcanologists at Yellowstone however fear its magma chamber as it is big enough to swallow Tokyo and believe it harbours at least one last punch. According to Professor Robert B Smith who wrote the book Windows into the Earth, Yellowstone could release two million tonnes of sulphuric acid: creating a nuclear winter, blocking out sunlight and causing worldwide famines. He states that the "devastation would be complete and incomprehensible.” with violent earthquakes, before the huge blast would wipe Yellowstone off the face of the Earth. Scientists estimate that 87,000 people would die instan...
Volcanoes are one of the most terrifying and spine-chilling natural calamities that is known to mankind. It is a constant reminder of the fearsome power of Mother Nature.
One form of alternative energy is called geothermal energy. Geothermal energy is thermal energy that is created and stored beneath earth’s crust. The most recognizable form of geothermal to most people would be in the form of a hot spring. Heat from Earth’s core heats rock and water differently; some spots can reach up to 700 degrees, whereas some receive not much heat at all. Steam from the water that receives the most heat is trapped in porous rocks underground. This is called a geothermal reservoir. Geothermal energy is very useful because it is renewable, and limitless. Heat continuously flows from the earth’s core, and continues to heat the water and produce steam. Geothermal is also useful because it is 80 percent cheaper than fossil fuels, and it requires no fuel. In fact, the use of geothermal energy decreases the independence on fossil fuels greatly. Geothermal energy does not produce pollution and could potentially save millions of dollars per year if used to replace fossil
The amount of heat and quantity is very high to produce geothermal energy; even though it is a very good source of energy there are downfalls. Geothermal is not a widespread source of energy. Because it isn’t a common source of energy, there is a lack of equipment, employees, and infrastructure to develop this type of energy. Along with this ...
Geothermal energy is renewable energy because once water or steam can be used, it could be pumped back into the floor. Additionally, it is clean energy. Geothermal power plants, unlike, don't produce greenhouse gases that can be harmful to the atmosphere. Geothermal energy is easy on the neighborhood environment since the power plants usually do not require the clearing of large areas of land, mining like other energy sources or damming of rivers. It is cheap to use. The source of energy is liberated to work with after a geothermal system is installed and there are often low maintenance costs involved because the plants use very few moving parts. It also reduces a country's dependence on imported oil, which cannot be
Most of the geothermal heat does not bubble out as magma, water of steam, but instead, it is stored in the mantle, collecting as pockets of heat. By drilling and pumping down water to create steam, this energy can be harnessed.
Geothermal energy is the thermal (heat) energy within the planet. Its is considered a renewable source of energy as it has always been around for for an abundant amount of years it will probably still be used in the next years because its source is the almost unlimited amount of heat generated by the Earth's core. Even in geothermal areas dependent on a reservoir of hot water, the volume taken out can be injected, making it a sustainable energy
Volcanoes can be one of the most destructive forces on Earth. It is estimated that some
Geothermal energy is one of the oldest sources of energy. It is simply using and reusing (reusable energy) heat from the inside of the earth. Most of the geothermal energy comes from magma, molten or partially molten rock. Which is why most geothermal resources come from regions where there are active volcanoes. Hot springs, geysers, pools of boiling mud, and fumaroles are the most easily exploited sources. The ancient Romans used hot springs to heat baths and homes, and similar uses are still found in Iceland, Turkey, and Japan. The true source of geothermal energy is believed to come from radioactive decay occurring deep within the earth.
Nuclear energy. we only really hear this term outside of chemistry when stories of disasters are broadcasted on TV. Chernobyl, and Fukushima being the two most prominent ones in our minds. We see these disasters happen, but what about the prominent real benefits of this type of energy. If we take proper care of our nuclear energy plants, then the U.S. should absolutely continue using it.
In same places such as Iceland, hot water comes naturally to the surface as steam, which can drive turbines to generate electricity, Some power stations make use of lava that flows from the volcanos. Despite of few disadvantages, it is an undeniable fact that geothermal energy is an extremely valuable, simple and clean source of energy that can benefit mankind in a big way.
Volcanos are amazing and frightening geologic features of our earth. Their volcanic ash feeds the farmlands, but that same ash from a violent eruption destroys crops. There are numerous volcanic eruptions that have changed the world. These eruptions include Mt. Saint Helens, Kilauea, Pompeii, and Pinatubo. The purpose of this paper is to describe the jeopardy of a volcano in the United States.
