Geothermal energy in Iceland is the proof alternative energy is already here and can be a quite lucrative field to get into. What is more, the vast fields in the Icelandic regions show that with clever planning, this kind of energy can easily and consistently supply the needed energy on a continuous basis, simply by working with the locale’s placement on the globe.

Looking to the generation and use of geothermal energy in Iceland as an example for the endless possibilities not nearly sufficiently exploited in the United States, it does bear mentioning there are already 43 such fields in the US. Granted, in comparison with the geothermal energy in Iceland, America does not come close in productivity and functionality.

There are three main power plant technologies used today in geothermal power plants. These technologies are used to convert hydrothermal fluids to electricity. Each type depends on the state of the fluid and its temperature.

Dry steam power plants were the first geothermal power plants of their kind. They traditionally use steam to produce electricity. This is done by taking steam from the geothermal reservoir and routing it through turbine units. The most common types of these plants are flash steam plants where water is pumped at high pressures at the surface.

Geothermal energy is energy generated from the heat stored in the earth. This energy resource is a renewable resource, which is a natural resource naturally replenished such as sunlight, rain or wind.

Geothermal energy is most commonly used through Binary Cycle power plants. Pumps are used to pump hot water from a geothermal well in the earth to a heat exchanger, which cools the water and returns it to a reservoir.

The National Renewable Energy Laboratory (NREL) is a research facility that is part of the United States Department Of Energy (DOE). The Research and Development expertise are with Renewable Electricity, Renewable Fuels, Integrated Energy Systems and Strategic Energy Analysis. These technologies are distributed by the Technology Transfer Office of the NREL whose main function is to introduce renewable energy and energy efficiency technologies to the public and the marketplace. These technologies can then be transferred into commercial products and businesses.

No discussion of renewable energy would be complete without paying some attention to the bystanders sometimes left out of the discussions: geothermal and hydro electric energy.

Although they are not considered to be of serious impact at this stage, they do present energy options for localized communities who might wish to subsidize their power grid with another source of readily available energy that lessens their dependence on the main form of energy.

Geothermal energy is used for electrical power production in 21 countries, and supplies significant amounts of electricity to countries such as the Philippines, where 27 percent of electricity derives from geothermal sources.

Geothermal energy is a mainstay of the Icelandic economy, and is also heavily exploited in the United States, with 43 geothermal plants. Geothermal energy is used for electric power generation and direct utilization in the United States.

Even so, this worldwide use represents only a fraction of the potential power that could be generated from geothermal resources. Geothermal energy is generally a highly localized resource, and the processes used to extract energy move at a much higher rate than the processes that restore energy into the geothermal environment.
