Geothermal energy is energy produced by geothermal water. Breaking geothermal down- Geo=earth, thermal=hot. Magma seeps through the earth's core, and gets stopped by rocks, sometimes heating underground ponds. An example of this is a hot spring. Hot springs are created by the same method, the water's just closer to the surface. The water is used in a plant that boils it and uses the steam to turn a turbine. The water will sometimes then be turned back into water and put into the pond for heating and further use. A Binary geothermal power plant uses the hot water to heat isopentain, which has a lower boiling point that water. The water is then put back into the earth to heat it up again. Geothermal power can be used for heating or even powering houses. Because it releases no bad emissions, it's a very clean form of energy.

The one that I would be most interested in using is geothermal energy. There are some really exciting new applications of geothermal energy for use in heating and cooling homes that essentially involve putting a heat pump deep enough underground that it reaches the soil zone where the temperature is constant year round. This results in having a source of heat in winter and a heat sink for cooling in summer. Every house should have one!!!\n\nSadly the new energy plan proposed by the administration cut geothermal energy research to ZERO.

What Is Geopathic Stress?\n\nGeopathic Stress is natural radiation that rises up through the earth and is distorted by weak electro-magnetic fields created by subterranean running water, certain mineral concentrations, fault lines and underground cavities. The wavelengths of the natural radiation disturbed in this way become harmful to living organisms.\n\nElectropathological energy created by modern technology can also contribute to geopathic stress in the form of high and low frequency energy from telecommunication towers, electricity pylons, transformers, radar and radio towers.

Check out this site: http://www.expanding-earth.org/\nSome scientists may dispute the notion that additional solid matter is created from solar energy by photosynthesis in plants and other living organisms, but they should consider coal beds that were formed from trees in the Carboniferous (~360 to ~290 Ma) but are now buried under deep overburden that accreted later. The huge fossilized tree trunks found in the Petrified National Forest near Holbrook in eastern Arizona are additional evidence of mass from solar energy. Also consider the massive deposits of limestone created by marine fauna (fish, coral, bivalves, microfossils, etc.) in earlier epochs and this growth continues today. Today, piles of leaves, wood chips and fallen trees are rapidly converted to soil by nematodes.  The whole question of added mass needs further research to more accurately determine the volume and sources.

Green energy that includes natural enegetic processes.  Geothermal power, wind power, small-scale hydropower, solar power, biomass power, tidal power and wave power fall under such a category. Some versions may also include power derived from the incineration of waste.\n\nRemember that no power source is impact-free. For instance, concerns are raised over bird kills and in some cases noise pollution by windmills and over heavy metal use and associated mining damage by raw materials used for constructing solar cells.\n\nHere in Greece we have used windmills  ancients before electricity but now we use it to produse electricity for our islands. We use also solar cells and  small-scale hydropower to produse electicity.

The sun is not the source of ALL the energy - just almost all of it.  \n\nLight is a form of energy, most of our light is from the sun but we do recieve a tiny fraction of light from the other stars in the sky - that is why we can see them.\n\nBut the sun does supply almost all the energy.\nThe sun radiates light and other forms of energy which hits the earth and some is absorbed (some is also reflected).  Much of the absorbed light becomes heat - this is why it is hotter in the sunshine than the shade.\nSunlight also allows plants to obtain energy by a process called photosynthasis which happens in leaves and green stalks (like on a cactus).  It is this energy from sunlight which allows plants to grow.  All living things use this energy from plants via the food chain.\nFuels (like coal and oil) come from the remains of plants and animals and thus the energy was originally from the sun.\n\nThere are sources of energy which don't come from the sun such as geothermal power (this is heat from the centre of the earth which is created by pressure) and there are even organisms which live deep in the ocean which do not need any sunlight to survive (they are chemotrophic bacteria which survive around active volcanic vents in the sea floor).  \nBut to all intents and purposes a good 99% of all the energy comes from the sun.\n\nI hope this helps you with your homework!

The only renewable mineral deposit that I saw I was in Andes (it was called 'salar '). The miners work this mine periodically (harvest), therefore it had thermal sources. This sources , deposit (all the time)  thermal waters, with same kind of minerals solved in it.\n\nRenewable mineral resources on to other planets? I don't know!

Geothermal power is the use of geothermal heat for electricity generation. It is often referred to as a form of renewable energy, but because the heat at any location can eventually be depleted it technically may not be strictly renewable. Geothermal comes from the Greek words geo, meaning earth, and therme, meaning heat. Geothermal literally means earth heat.\n\nGeothermal power is generated by mining the earth's heat. In areas with high temperature ground water at shallow depths, wells are drilled into natural fractures in basement rock or into permeable sedimentary rocks. Hot water or steam flows up through the wells either by pumping or through boiling (flashing) flow. Experiments are in progress to determine if a fourth method, deep wells into "hot dry rocks", can be economically used to heat water pumped down from the surface. A hot dry rock project in the United Kingdom was abandoned after it was pronounced economically unviable in 1989. HDR programs are currently being developed in Australia, France, Switzerland and Germany. Magma (molten rock) resources offer extremely high-temperature geothermal opportunities, but existing technology does not allow recovery of heat from these resources.\n\n\nElectrical generation\nGeothermal-generated electricity was first produced at Larderello, Italy, in 1904. Since then, the use of geothermal energy for electricity has grown worldwide to about 8,000 megawatts of which the United States produces 2,700 megawatts.\n\nThree types of power plants are used to generate power from geothermal energy: Dry steam, flash and binary. Dry steam plants take steam out of fractures in the ground and use it to directly drive a turbine that spins a generator. Flash plants take hot water, usually at temperatures over 200C, out of the ground, and allow it to boil in steam separators and then run the steam through a turbine. In binary plants, the hot water flows through heat exchangers, boiling an organic fluid that spins the turbine. The condensed steam and remaining geothermal fluid from all three types of plants are injected back into the hot rock to pick up more heat. This is why geothermal energy is viewed as sustainable. The heat of the earth is so vast that there is no way to remove more than a small fraction even if most of the world's energy needs came from geothermal.\n\nThe largest dry steam field in the world is The Geysers, about 90 miles (145 km) north of San Francisco began in 1960 which has 1360 MW of installed capacity and produces about 1000 MW net. Calpine Corporation now owns 19 of the 21 plants in The Geysers and is currently the United States' largest producer of renewable geothermal energy. The other two plants are owned jointly by the Northern California Power Agency and Santa Clara Electric. Since the activities of one geothermal plant affects those nearby, the consolidation plant ownership at The Geysers has been beneficial because the plants operate cooperatively instead of in their own short-term interest. The Geysers is now recharged by injecting treated sewage effluent from the City of Santa Rosa and the Lake County sewage treatment plant. This sewage effluent used to be dumped into rivers and streams and is now piped to the geothermal field where it replenishes the steam produced for power generation.\n\nAnother major geothermal area is located in south central California, on the southeast side of the Salton Sea, near the cities of Niland and Calipatria, CA. As of 2001, there were 15 geothermal plants producing electricity in the area. CalEnergy owns about half of them and the rest are owned by various companies. Combined the plants produce about 570 megawatts.\n\nThe Basin and Range geologic province in Nevada, southeastern Oregon, southwestern Idaho, Arizona and eastern Utah is now an area of rapid geothermal development. Several small power plants were built during the late 1980s during times of high power prices. Rising energy costs have spurred n

Solar energy ( using solar panels or something ) is the ultimate alternate energy source, because the energy in living things comes from the sun.  The energy in petroleum, which comes from dead plants, comes from the sun.  And the energy from hydroelectric dams comes from the sun, because the sun evaporates the water so it can rain down on the mountains and fill up the reservoir behind the dam.  Why not just go directly to the source--the sun.\n\nAs for simulating day and night, you must do this!  The human body schedules itself to sleep about every 24 or 25 hours.  Going against this schedule or against the schedule of light and dark periods can cause difficulty sleeping, difficulty staying awake, and possibly psychological problems.\n\nI don't really know what kind of colony you are referring to, so I can't really answer the other questions.  Is it a computer simulation, like Sim City, or a science-fiction colony on the planet Mars, or just a wilderness survival plan?
