alternative.energy The Solutions, Now Geothermal Energy What is geothermal energy? How do people exploit such resources? How is this alternative energy better than what we are using now? Is geothermal energy perfect? What is geothermal energy? How do people exploit such resources? Geothermal energy is the heat contained within the earth. It is estimated that the temperature in the core of the earth is at least 6650 o C. Yet, the earth is cooling down very slowly: at the rate of 300 to 350 o C within three billion years. There is 42X10 W of heat in the earth, of which 2% is in the crust and 98% in the mantle and core. With today's technology, it would be impossible to access the energy that reside too deep within the earth, but the 840 000 000 000 W (2%) of geothermal energy that is accessible is sufficient for humans to use for a long period of time. o C) so that the steam can push the turbine to produce electricity. How is this alternative energy better than what we are using now? Geothermal energy is localized and no fuel is required. This makes geothermal energy economical and eliminates the chance of damaging the environment during transportation, storage and usage. Also, the supply of geothermal energy is continuous and will not be fluctuated by any political or economical factors. Is geothermal energy perfect?

Geothermal, An Energy Alternative? What is geothermal energy? Geothermal energy is generated when water contacts hot rocks below the earth's surface. The rocks give off hot steam which is used for electricity. This is geothermal energy. Geothermal means earth-heat. On the island of Hawai'i, geothermal wells have been dug to test the use of geothermal energy for making electricity. There has been a big debate whether geothermal energy does more harm than good. Geothermal energy costs less and is a relatively safe way to make electricity. It will also help free the islands from importing oil and coal for energy. Although oil is cheaper than a few years ago, it is quickly being used up. People who are for the use of geothermal energy say it is cleaner for the environment than energy from coal and oil. The people who are against geothermal say that Hawaiian rain forests are cut down to make roads and buildings for the geothermal plants. If the Hawaiian rain forests are cut down, many endangered native plants and animals may become extinct. Some of these plants and animals live only in this area. Furthermore, steam from geothermal plants is full of sulfur and other chemicals. If you breathe too much of the gas, it may be toxic. It is also dangerous to handle without the right equipment. Many people on the Big Island became afraid following leaks from a test well. The power plant that was built afterwards and runs today is very quiet and is self-contained so the sulfurous steam is not released into the air.

Geothermal Energy How it works Geothermal simply means 'Earth's heat'. The centre of the Earth is extremely hot, current estimates are 5,500C at the core just over six and a half thousand kilometres below the crust. This is about as hot as the surface of the sun. It is not surprising therefore, that even the upper 3 metres of the Earth's surface stay at a nearly constant 10-16C throughout the year. There are three main ways of tapping geothermal energy: Direct use Geothermal heat found near the surface of the Earth can be used directly for heating buildings (District Heating - the system that supplies communities with hot water or heating - being the most well known) and for a number of commercial and industrial uses. Geothermal heat pumps The relatively constant temperature of the top 15 metres of the Earth's surface (or ground water) can be used to heat or cool buildings indirectly. The pump uses a series of pipes to circulate fluid through the warm ground. In the winter when the ground is warmer than the buildings above, the liquid absorbs heat from the ground, which is then concentrated and transferred to the buildings. This can also be used to heat domestic water. In the summer, when the ground is cooler, the pump transfers heat from the buildings back into the ground.

Feature Articles Title/Description Available Formats Analysis of Geothermal Heat Pump Manufacturers Survey Data The Energy Information Administration (EIA) collected information on shipments of geothermal heat pumps, often called ground source or geoexchange systems, for the first time in 1997. This information is based on data filed on the EIA’s Form EIA-902, "Annual Geothermal Heat Pump Manufacturers Survey." In addition to discussing geothermal heat pump shipment data, this article describes how geothermal heat pumps work, system economics, and provides two case studies, including the Department of Energy’s role in geothermal heat pump development. Keywords: Energy, Geothermal, Heat Pump PDF Transmission Pricing Issues For Electricity Generation From Renewable Resources This article discusses how the resolution of transmission pricing issues which have arisen under the Federal Energy Regulatory Commission’s (FERC) “open access” environment may affect the prospects for renewable-based electricity. After giving some preparatory material on the deregulated electricity market and on renewable energy characteristics relevant to electricity transmission, the article discusses alternatives being considered for pricing transmission, provides qualitative impacts of those choices on renewable electricity transmission costs, and concludes with alternatives for reducing renewable-based electricity transmission costs.

GEOTHERMAL ENERGY SITE INDEX CATAMARAN HULL SOLAR PANELS ELECTRIC MOTORS ... GOODIES G eothermal energy is a proven resource for direct heat and power generation. In over 30 countries geothermal resources provide directly used heat capacity of 12,000 MW and electric power generation capacity of over 8,000 MW. It meets a significant portion of the electrical power demand in several developing countries. For example, in the Philippines geothermal provides 27% of that country's total electrical generation, from power plant complexes as large as 700 MW. Costs of geothermal electric power are very dependent on the character of the resource and project size. The unit costs of power currently range from 2.5 to over 10 US cents per kilowatt-hour while steams costs may be as low as US$3.5 per tonne. Major factors affecting cost are the depth and temperature of the resource, well productivity, environmental compliance, project infrastructure and economic factors such as the scale of development, and project financing costs.
