Energy Efficiency And Renewable Energy Network (Eren) : Our intention
has been to provide the reader with a balanced overview of the utility-scale
geothermal power industry. We believe clean, reliable power can be developed from
renewable resources, with geothermal power making an important contribution.
Examples from the U.S. geothermal sector have been used to illustrate the costs,
benefits, policies, and trends in geothermal energy today. What follows is a list
or further resources available on the worldwide web to allow the reader to gain a
deeper understanding of the potential of geothermal power and the issues
surrounding its development. We urge the reader to seek further understanding of
these issues, and the means to their resolution, in order to support the progress
of geothermal energy in providing clean, reliable, and economic power.

Finding Hidden Geothermal Resources In The Basin And Range Using Electrical Survey
Techniques - A Computational Feasibility Study December 2004 : The
commercial viability of geothermal power production is influenced by capital costs
for land, drilling, and physical plant; operating and maintenance costs; the
amount of power generated and sold from the plant; and the market value of that
power. However, because geothermal power plants incur high capital costs at the
beginning of the project, they are typically at an economic disadvantage to
conventional fossil fueled power plants. Fossil fuel plants have lower up-front
capital costs, but incur fuel costs for the life of the plant. This section
discusses capital cost, operating and maintenance cost, average cost of power
production over the life of the plant (known as the levelized cost of power
production), as well as the economic impacts of geothermal power such as labor
creation, tax base contributions, and balance-of-trade impacts. |

Geothernet Geothermal Information For Europe: Utility-scale geothermal
power production employs three main technologies. These are known as dry steam,
flash steam and binary cycle systems. The technology employed depends on the
temperature and pressure of the geothermal reservoir. Unlike solar, wind, and
hydro-based renewable power, geothermal power plant operation is independent of
fluctuations in daily and seasonal weather. |

History Of Geothermal: new link --
Understanding geothermal energy begins with an understanding of the source of this
energy—the earth’s internal heat. The Earth’s temperature increases with depth,
with the temperature at the center reaching more than 4200 °C (7600 °F). A portion
of this heat is a relic of the planet’s formation about 4.5 billion years ago, and
a portion is generated by the continuing decay of radioactive isotopes. Heat
naturally moves from hotter to cooler regions, so Earth’s heat flows from its
interior toward the surface |

Renewable Northwest Project: Geothermal energy is energy derived from
the heat of the earth’s core. It is clean, abundant, and reliable. If properly
developed, it can offer a renewable and sustainable energy source. There are three
primary applications of geothermal energy: electricity generation, direct use of
heat, and ground-source heat pumps. Direct use includes applications such as
heating buildings or greenhouses and drying foods, whereas ground source heat
pumps are used to heat and cool buildings using surface soils as a heat reservoir.
This paper covers the use of geothermal resources for production of utility-scale
electricity and provides an overview of the history, technologies, economics,
environmental impacts, and policies related to geothermal power.

The Geothermal Energy Association: Renewable energy can reduce
dependence on fossil fuels, reduce harmful pollution from energy production and
consumption, and reduce emissions of greenhouse gases. However, most renewables
have very different cost structures from conventional energy generating
technologies, with high up-front costs and low operating costs. This is true for
geothermal energy, which has high exploration and drilling costs in additional to
capital plant expenses. |
