Geothermal Energy

Geothermal energy has been used for thousands of years in some countries for cooking and heating. It is simply power derived from the Earth’s internal heat.

This thermal energy is contained in the rock and fluids beneath Earth’s crust. It can be found from shallow ground to several miles below the surface, and even farther down to the extremely hot molten rock called magma.

How Is It Used?

Geothermal Energy

These underground reservoirs of steam and hot water can be tapped to generate electricity or to heat and cool buildings directly.

A geothermal heat pump system can take advantage of the constant temperature of the upper ten feet (three meters) of the Earth’s surface to heat a home in the winter, while extracting heat from the building and transferring it back to the relatively cooler ground in the summer.

Geothermal water from deeper in the Earth can be used directly for heating homes and offices, or for growing plants in greenhouses. Some U.S. cities pipe geothermal hot water under roads and sidewalks to melt snow.

Production of Geothermal Energy

To produce geothermal-generated electricity, wells, sometimes a mile (1.6 kilometers) deep or more, are drilled into underground reservoirs to tap steam and very hot water that drive turbines linked to electricity generators. The first geothermally generated electricity was produced in Larderello, Italy, in 1904.

There are three types of geothermal power plants: dry steam, flash, and binary. Dry steam, the oldest geothermal technology, takes steam out of fractures in the ground and uses it to directly drive a turbine. Flash plants pull deep, high-pressure hot water into cooler, low-pressure water. The steam that results from this process is used to drive the turbine. In binary plants, the hot water is passed by a secondary fluid with a much lower boiling point than water. This causes the secondary fluid to turn to vapor, which then drives a turbine. Most geothermal power plants in the future will be binary plants.

Geothermal energy is generated in over 20 countries. The United States is the world’s largest producer, and the largest geothermal development in the world is The Geysers north of San Francisco in California. In Iceland, many of the buildings and even swimming pools are heated with geothermal hot water. Iceland has at least 25 active volcanoes and many hot springs and geysers.

About Geothermal Energy

  1. What Is Geothermal Energy?

Geothermal energy comes from the heat within the earth. The word “geothermal” comes from the Greek words geo, meaning earth,” and therme, meaning “heat.” People around the world use geothermal energy to produce electricity, to heat buildings and greenhouses, and for other purposes.

The earth’s core lies almost 4,000 miles beneath the earth’s surface. The double-layered core is made up of very hot molten iron surrounding a solid iron center. Estimates of the temperature of the core range from 5,000 to 11,000 degrees Fahrenheit (F). Heat is continuously produced within the earth by the slow decay of radioactive particles that is natural in all rocks.

About Geothermal Energy

Surrounding the earth’s core is the mantle, thought to be partly rock and partly magma. The mantle is about 1,800 miles thick. The outermost layer of the earth, the insulating crust, is not one continuous sheet of rock, like the shell of an egg, but is broken into pieces called plates. These slabs of continents and ocean floor drift apart and push against each other at the rate of about one inch per year in a process called continental drift.

Magma (molten rock) may come quite close to the surface where the crust has been thinned, faulted, or fractured by plate tectonics. When this near-surface heat is transferred to water, a usable form of geother- energy is created.

Geothermal energy is called a renewable energy source because the water is replenished by rainfall, and the heat is continuously produced by the earth.

  1. History of Geothermal Energy

Many ancient peoples, including the Romans, Chinese, and Native Americans, used hot mineral springs for bathing, cooking, and heating. Water from hot springs is now used world-wide in spas, for heating buildings, and for agricultural and industrial uses. Many people believe hot mineral springs have natural healing powers.

Using geothermal energy to produce electricity is a relatively new industry. It was initiated by a group of Italians who built an electric generator at Lardarello in 1904. Their generator was powered by the natural steam erupting from the earth.

The first attempt to develop geothermal power in the United States came in 1922 at The Geysers steam field in northern California. The project failed because the pipes and turbines of the day could not stand up to the abrasion and corrosion of the particles and impurities that were in the steam. Later, a small but successful

Geothermal Energy within your Household? It could Occur

It needs to be noted that the idea of generating use of geothermal power for sensible consumption just just isn’t new. Firms had been putting it into play practically a hundred years ago following they utilized earth-borne steam to power many machineries. This is the basic premise behind the energy-it uses the natural heat from the planet’s core to power whatever requirements to be powered. This actually is an limitless source, because the Earth will often be creating its own heat and absorbing excess heat from the sun.

Geothermal Energy within your Household? It could Occur

To get the power, the method entails drilling deep in towards the ground and employing systematic technologies to transfer the stored heat into a conductor following which on into a heat pump. Unlike some other forms of energy, an excellent deal a great deal a lot much less kinetic energy is spent extracting this heat than is retained by the method. Greater nevertheless, the approach is substantially cleaner and safer than, say, the process of drilling for shale gas, which has designed an massive volume of controversy even as people hail the added benefits of one’s gas itself. As the technology grows, it has create to become further and much more feasible to use geothermal sources for electrical energy within the property. Inside a country for example Iceland, practically 90 % of the country’s electrical energy comes from this pretty supply. That quantity is only expected to develop inside the coming years.

Although the added benefits for the environment are staggering, this kind of technology isn’t sold on those benefits. Unfortunately, there merely aren’t sufficient men and women who see international warming as enough of a threat to modify their strategies in any dramatic manner. Unless you will obtain in reality government mandates, It could Take far more to acquire folks to switch over from their conventional energy sources. However, that may very well occur. As the expenses of installation go down, property owners will begin to figure out how much funds they’re in a position to save on their monthly electric bill by performing their heating in this manner. When this becomes frequent knowledgePsychology Articles, anticipate to determine a genuine groundswell of assistance for the technology.

Exciting Power Details

Geothermal ActivityGeothermal power is a extremely handy, virtually inexhaustible clean energy source for these regions fortunate adequate to uncover themselves on top of it. Enormous amounts of hot rock just under the Earth’s surface can be utilized to heat water and drive steam turbines for dependable electrical energy generation with virtually no emissions or environmental influence.

The power used by the industrial sector accounts for about 13% of total energy demand in Canada, and about the exact same amount of greenhouse gas emissions from secondary energy use. Earth’s temperature rises with depth from the surface to the core. This gradual change in temperature is recognized as the geothermal gradient In most components of the globe, the geothermal gradient is about 25° C per 1 kilometer of depth (1° F per 77 feet of depth).

Boston Pacific Company asserted that HELCO should continue to retain the integrity of the rules of the RFPs. That implies, for example, holding bidders to their cost and efficiency estimates during the negotiation phase and treating all bidders equally in the evaluation process.
