the reservoir is to be used for direct-heat application‚ the geothermal water is usually fed to a heat exchanger before being injected back into the earth. Heated domestic water from the output side of the heat exchanger is used for home heating‚ greenhouse heating‚ vegetable drying and a wide variety of other uses. Hot water and steam exist at many subsurface locations in the western U.S. These resources can be classified as low temperature (less than 194 degrees F)‚ moderate temperature (194

Geothermal Energy Abstract The purpose of this report is to introduce the background of geothermal energy‚ different types of this energy‚ several applications and some disadvantages of geothermal energy. The scope and limitation of this report include the international development of geothermal energy and it benefits for human beings‚ thereby‚ providing incentive for the implementation of development of geothermal energy in Australia. However‚ due to the geological factor‚ the cost of the application

Geothermal energy has for many years been used in some parts of the world while heating as well as cooking. The mechanism used to produce this unique power uses a geothermal heat pump system‚ which takes advantage of the temperatures below the surface of the earth and thus‚ is utilized while providing heat during winter.

Other large companies or institutions may have their own usually smaller power plants to supply heating or electricity to their facilities‚ especially if heat or steam is created anyway for other purposes. Shipboard steam-driven power plants have been used in various large ships in the past‚ but these days are used most often in large naval ships. Such

SECTION 2: TIME VALUE OF MONEY Decision problems in business usually involve a decision over whether to accept one alternative over another‚ or whether to implement a plan or not. In most cases‚ the effects of these decisions are felt in the future. Examples: Expand into a new market (geographical‚ consumer segment‚ etc.) or not? Now or later? Outsource production or keep it in-house? Grow organically or acquire a competitor? Or don’t grow at all? Purchase shares in Microsoft
