GEOTHERMAL
Respond to this post with information about geothermal energy.
Geothermal energy is derived from heat created by the earth’s core and from water. There are several advantages to geothermal energy, compared to other forms. It is eco-friendly and is generally referred to as the clean energy. Geothermal energy is not extracted from fossil fuels and it gives off about three percent of CO2. The human race is face to face with some serious problems involving the environment, including global warming and pollution. Because yearly rainfalls replace the water level, the heat is constantly generated from the earth’s crust
Geothermal energy is energy that comes from the inside of the earth. We can capture the heat, that comes under the ground and transform it into steam to generate efficient energy.
Hot water’s been used as an energy source since ancient times. Many cultures used hot ponds of water for cooking, bathing, and heating. A lot of people think that mineral-filled hot water has healing powers. Hot water is also used for heating buildings. Dehydrating food is one the most common uses of geothermal energy.
Under volcanoes is where we find the hottest temperatures. Most of the “hot spots” are around plate boundaries or by thin crusted areas of the earth. Some of the most abundant areas are around the ring of fire, or the Pacific Rim. Some hot spots in the united states are in Alaska, Californian, and Oregon. The most is in Nevada, most of the northern state is covered in volcanoes.
Geothermal energy is energy that is taken from the heat deep beneath the earth’s surface. This energy is taken from the earth as either steam or hot water. These forms of heat can be used for energy to heat buildings or to generate electricity.
Geothermal power plants use steam, heat, or hot water is pumped up from its reservoir in the earth’s surface, and provides enough force to spin turbine generators that will produce energy. Then the water is placed back into the underground so it will get reheated and then re-used.
The surface under the earth’s crust is hot dry rock which is being heated by the magma which is directly under it. People are developing technology so we will be able to take the steam that arises from the magma and convert it into energy.
By using geothermal energy everyone can save up to 38,820 tons of CO2 emissions daily. 7,861,526 tons of emissions have been saved since 2009 there has been over 7,925,695 avoided emissions yearly
Geothermal energy is produced by groundwater heated by reservoirs of molten rock usually 9,800 feet underground. Wells similar to the ones that produce oil and natural gas are drilled to recover the water. The steam and water are captured and separated. The steam is cleaned and sent to the power plant and the water is returned to the reservoir.
The natural heat of the earth creates geothermal energy. When ground water travels under a dormant volcano, the molten rock heats it. Once captured, the steam and water are separated. After the steam is cleaned it is sent to a power plant. The water is sent back to the ground water reservoir.
Geothermal is very useful and not hard to use. All you have to do is get a deep well that you can pump the geothermal water which will become electricity for your home, and heat your whole house. It can also cool your house which is a benefit for the summer.
Geothermal energy power plants, drill holes into rocks to more effectively capture steam. Earth’s crust is heated up and then rises to the surface. When water is heated up it is forced to the surface. To drive electric generators is a simple matter to capture steam.
There is a well in the ground that gets heat from the earth’s or from being close to the core . to it. That produces hot water and steam and powers a turbine that transfers electricity.
Geothermal is among the most natural alternative energy sources known to man. For geothermal energy, we obtain heat from the earth and it never runs out because the earth will always be hot. As technology begins to expand, we will be able to dig even further into the earth’s surface and reach even hotter temperatures. The hotter the temperature, the more energy we can provide to cities and countries across the world.
Geothermal is heating and cooling. The most efficient fuel burning heater can reach efficiencies around 95%. Geothermal is run by “heat pumps” and electricity.
In the earth’s core it is over 60 times hotter than boiling water. The heat is pressure created below the earth’s surface. We don’t have to go to the center of the earth
Hi... Geothermal is a resource that has been create but not harnessed for millions of years. Science has now brought discoveries of hot spots closer to the earth’s crust, with these spots we can heat water and turn turbine to generate electricity.

ReplyDeleteTo generate energy, a geothermal energy plant uses the hot and steamy underground water to spin a turbine and power a generator.

ReplyDeleteHydrogen will be better for our environment because it lets out water not carbon dioxide, and it would be better for cars rather than gasoline.
ReplyDeleteThe surface under the earth’s crust is hot dry rock which is being heated by the magma which is directly under it. People are developing technology so we will be able to take the steam that arises from the magma and convert it into energy.
ReplyDeleteGeothermal energy basicly is energy that createswarmth and power that we can use without polluting the environment.

ReplyDeleteGeothermal is the most used energy used in the United States and the top state that uses the most is Alaska.
ReplyDeleteGeo thermal energy works by extracting the heat in the earth and pumps that heat into a condition air space creating energy.
ReplyDeleteGeothermal energy is the energy that comes from heat that is below the earth’s surface. For example, heat coming from younger volcanoes
ReplyDeleteGeothermal is heating and cooling. The most efficient fuel burning heater can reach efficiencies around 95%. Geothermal is run by “heat pumps” and electricity.
ReplyDeleteGeothermal heating and cooling uses the earth’s temperature to heat and cool buildings at a cheaper cost than air condition or using heaters.
ReplyDeleteThe only difference is a geothermal heat pump does away with the outdoor equipment, the condensing unit, and replaces it with a heat exchanger.
ReplyDeleteThis is just when we drill holes into areas of the earth that are heated and water or steam will rise and we will use the heat as a source of energy
ReplyDeleteIn the earth’s core it is over 60 times hotter than boiling water. The heat is pressure created below the earth’s surface. We don’t have to go to the center of the earth
ReplyDeleteSolar energy can be used to heat homes, buildings in the world.
ReplyDeleteSolar energy is created by the sun’s hot rays.
