 //** Gas the past and Geo the future! **//      ** What is geothermal energy? **  ** The word Geothermal comes from the Greek words geo (earth) and "therme" (heat). Therefore geothermal energy is heat from within the earth. Geothermal energy is made by pumping water underground and exposing it t ** o heat. The steam or hot water goes up a pipe and then is separated. The steam goes into another pipe and spins a turbine. The hot water is purified and used as hot water. That is what geothermal energy is. ** Advantages **
 * // Clean. //**** Geothermal power plants do not have to burn fuels to manufacture steam to turn the turbines. Generating electricity with geothermal energy helps to conserve nonrenewable fossil fuels, and by decreasing the use of these fuels, we reduce emissions such as greenhouse gases that harm our atmosphere. There is no smoke around geothermal power plants -- in fact some are built in the middle of farm crops and forests, and share land with cattle and local wildlife! The land area required for geothermal power plants is smaller per megawatt than for almost every other type of power plant. Geothermal power plants don't require damming of rivers (Hydro Electric) or harvesting of forests (Biomass) -- and there is no major damage to the environment if done correctly. **
 * // Constant. //**** Geothermal power plants are designed to run 24 hours a day,7 days a week and all year round. A geothermal power plant is constructed right ** ** on top of its fuel source. **
 * // Flexible. //**** Geothermal power plants can have many designs, with additional units installed in increments when needed to fit growing demand for energy. **
 * // Money saving. //**** After installing a geothermal power plant in your house you can get year round energy and save $100s of dollars on your electricity bill which would be very good especially in these hard times. **

  **__ Disadvantages __**


 * One of the biggest disadvantages of geothermal energy is the low number of suitable locations for a power plant. An ideal location has suitable hot rocks at a depth that allows for easy drilling. The type of rock above the hot rocks must also be easy enough to drill through. We can solve this issue by getting more powerful drills to drill through rocks.

Another one of the disadvantages of geothermal energy is that sometimes the locations can run out of steam. This sometimes lasts for months. Or this lasts for decades. While there is no steam, the power plant won't have enough energy to generate electricity. We can solve this by creating a technology that can actually change to another pipe if one is not working.

Another disadvantage of geothermal energy is that it is not easily transported. It can only be used to generate electricity for surrounding areas. To solve the problem we could improve our technologies and make a device that can transport energy to places that we far away from the power plant that we cannot reach today.

One of the most common substances to be released is hydrogen sulfide, which is extremely difficult to dispose of safely. Other minerals that can be troublesome are arsenic, mercury, and ammonia. Geothermal energy doesn't just release hazardous gases and minerals, it can also cause earthquakes. To slove the issue we can purify the steam or water before it comes up. We also could create a device that can prevent earthquakes. ** ** The History and Future of Geothermal ** __ **Past** __
 * You are probably thinking how we first used geothermal energy. Here is the answer: **
 * From earliest times, people have used geothermal water that flowed freely from the earth's surface as hot springs. The oldest and most common use was, just relaxing in the comforting warm waters but, eventually, this "magic water" was used in other creative ways. As early as 10,000 years ago, Native Americans used hot springs water for cooking and medicine. The Romans used geothermal water to treat eye and skin disease and at Pompeii, to heat homes and buildings. That was how they used geothermal energy in the past. **




 * __ Present __**
 * Now let’s talk about how geothermal energy is used today: **
 * Today we drill wells into the geothermal reservoirs to bring the hot water and steam to the surface. Geologists, geochemists, drillers and engineers explore and test a lot to locate underground areas that contain this geothermal water or steam, so we'll know where to drill geothermal power plants. Then, once the hot water and/or steam travels up the wells to the surface, they can be used to generate electricity for many homes and buildings. **

** Now let’s talk about how geothermal energy will be used in the future: ** [|http://geothermic.tracto-technik.com/]
 * __ Future __**
 * First of all The Demand for energy will continue to grow. Economies are expanding, populations are increasing, and efficient energy technologies are spreading. One thing is clear all mean greater demand for energy. Using current technology geothermal energy from already-identified reservoirs can contribute as much as 10% of the United States entire energy supply. And with more exploration, the inventory can become larger. The entire world resource base of geothermal energy has been calculated in government surveys to be larger than the resource sites of coal, oil, gas and uranium __combined__. Geothermal resource sites become more available as technology advances. Therefore geothermal energy has a bright future and will be success.**

The Benifit for Upper Merion Geothermal is good for Upper Merion because they could reduce Green house gas that is harmful to the environment. It can save tax payers money by using geothermal energy to heat and power the townships municipal buildings and parks. By Upper Merion doing this they are helping the community to save money by using geothermal fuel efficiently. **   **__Why our group chose Geothermal energy__**
 * We chose geothermal energy because it is very efficient. Geothermal also does not need much so it is a great energy resource for Upper Merion Middle School. We also thought geothermal is easy to operate and you don’t have to cut down trees (Biomass) to get energy. That is why we chose geothermal energy. **
