Geothermal Energy In today's world, we are stuck in a constant debate about efficient energy usage and production. Many have gone to alternative fuel sources do to the rising cost of fossil fuels and the environmental damage caused by the burning of fossil fuels. One option that goes largely unexplored is geothermal energy. Geothermal energy is not only a much more environmentally-friendly power source than fossil fuels, but the cost of installation is not significantly more expensive than the installation of a new “High Efficiency” conventional heating system. The focus of this inquiry will be upon single-household use, however it will also delve into geothermal energy on an industrial scale. The first question any reasonable homeowner will ask is: “What is this installation going to cost me?” Based upon his 20+ years in the business of geothermal energy installation, maintenance and logistics, Jay Egg estimates the average cost of geothermal installation for a given household anywhere in the U.S. to be approximately $42,000. This number seems very high, however several factors greatly reduce the price for homeowners. The first is a 30% government income tax credit, which cuts the price down to $29,400. The next factor that needs to be considered is the annual savings of geothermal compared to conventional systems. A geothermal system will replace your need for a water heater, serve as your household heating and cooling unit, and will cut maintenance costs due to the incredible reliability of geothermal systems, Jay Egg estimates these savings to be a total of $2617 per year ($500/year for water heater, $1617/year in heating/cooling costs, $500 per year in maintenance cost for these two systems). Given these numbers, it would ... ... middle of paper ... ...e of Technology) 28 (3): 8–19, retrieved 2009-04-12 Pahl, Greg (2007),The Citizen-Powered Energy Handbook: Community Solutions to a Global Crisis, Vermont: Chelsea reen Publishing "American Geothermal Plants."

The author discusses the enticement to political groups because of geoengineering’s alleged potential to reverse global warming rapidly and cheaply, as he presents concern regarding the significant risks and the threat of technology gone wrong. The author looks at the basic authority issues raised by geoengineering, its possible functions, governance, and specifically addresses inadequate research funding, rejection, and unilateral vs individual action. Bodansky is a professor at Arizona State University Sandra Day O 'Connor College of Law and has written three books and dozens of articles and book chapters on international law, international environmental law and climate change policy. This article will be a useful tool in discovering
Instilling this new way of energy usage into off-grid communities will inevitably increase the state of living for those in cities and other well-populated areas. The change to renewable energy sources could drastically lower the pollutants currently being dispersed into the atmosphere by coal mines and other harmful power options, increasing the supply of renewable energy would allow us to replace carbon-intensive energy sources and significantly reduce U.S. global warming emissions. a 25 percent by 2025 national renewable electricity standard would lower power plant CO2 emissions 277 million metric tons annually by 2025—the equivalent of the annual output from 70 typical (600 MW) new coal plants (“Benefits of Renewable Energy Use”). Electricity production accounts for more than one-third of U.S. global warming emissions, with the majority generated by coal-fired power plants.
Two people who believe this are reporters at the Breit Bart News Network. Julian Morris and Victor Nava believe that, “‘Green’ energy subsidies benefit the politically connected while harming future generations as hundreds of millions of dollars are added to the country’s debt burden with each green failure.” In a way Morris and Nava are correct. According to Mathias Aarre Maehlum, “Residential solar systems are typically sized from 3 to 8kW and end up costing between $15,000 and $40,000.” This can add up to become very expensive when implementing solar energy throughout the country. However, with the advancements in technology growing every year the cost will decrease over time. The cost of implementation can in fact go down as well through the use of community solar gardens. This helps the homes that are shaded and cannot absorbs the Sun’s energy. The energy from the community solar gardens are shared through out those homes. Switching to solar energy can also save money over time. Rhone Resch, president of the Solar Energy Industries Association confirms this. Resch says, “Today, the solar industry employs nearly 175,000 Americans and pumps more than $15 billion a year into the U.S. economy – and we’re just scratching the surface of our enormous potential” (qtd. in
...Kroeker designed the first commercial geothermal heat pump to heat the Commonwealth Building in Portland, Oregon and demonstrated it in 1946. In 1960, Pacific Gas and Electric began operation of the first successful geothermal electric power plant in the United States at The Geysers in California. The original turbine lasted for more than 30 years and produced 11 MW net power. The binary cycle power plant was first demonstrated in 1967 in the U.S.S.R. and later introduced to the U.S. in 1981. This technology allows the generation of electricity from much lower temperature resources than previously. (Wikipedia, 2011)

First let’s begin with the history of geothermal, it goes back a lot further than you would think. Geothermal can be traced back to over 10,000 years ago to being used by the Paleo Indians with their homes being near hot springs. Evidence shows that the Indians used the hot springs for activities that included heating of their homes and bathing. They even saw the hot springs as a healing source, which is agreeable if you have ever sat in one of those things, then you have experienced firsthand the primitive use of geothermal energy. In 1922, the first geothermal power plant in the U.S. went down in history for producing 250 Kilowatts of power, which could successfully light the streets and buildings in the area. This plant didn’t last very long because of its small output of power compared to other sites across the g...

Electricity is one of the biggest outputs of geothermal energy. It was first recorded to produce electricity in 1904 in Italy. There are now geothermal power plants in operation in New Zealand, Japan, Iceland, the US and elsewhere.
Solar thermal energy is dead! A solar thermal heating system can cost upwards of $7,000 to install and it most likely won't even save you too much money. This is why many people debate over whether they should use a solar thermal water heating system, because they think they are saving money, or an inexpensive traditional water heating system. A traditional heating system is a system that is powered off of electricity, gas, oil or some other fuel. A solar thermal heating system uses the energy from the sun, hence “solar”, and it turns that energy into hot water to either heat a home or to provide domestic hot water. The energy from the sun is captured by energy collectors, also known as solar panels. The water is heated inside the panels and then distributed throughout the home for use or stored in a tank for later use. The ideas behind this sound great, but in reality that is not the case.Solar thermal energy is not the best choice for home heating a home or hot water heating.

There are many benefits of using solar water heaters. Sunlight is free and environmentally friendly and this planet has so much to use(“Getting better acquainted”). The sun’s energy is renewable, suns energy is all over the world (“Getting better acquainted”). Solar energy has many uses, and it can be stored and used. “Solar energy can be used in many ways to provide heat, lighting, mechanical power, and electricity” (“Getting Better Acquainted”). New steps are being made in solar technology to save resources. America will save so much money and many barrels of oil by switching to solar power, “Skyrocketing fuel prices and tax credit of nearly 30% established in the energy policy act of 2005”(“Tapping into the sun”). The solar water system won’t cost much only “$3000 to $6000” (“Tapping into the sun”) so it will be affordable. “The technology can cut the average family’s costs to heat water by 20 to 40 percent (as much as 90% in some southwestern regions)”(“Tapping into the sun”).

There are various ways which one can space heat their house. The most common way is to use a furnace, however, stoves, fireplaces, electric resistance heaters and electrically powered heat pumps can also be used to heat the house. Furnaces run mostly off natural gas and tend to be around 60-90% efficient. Older units can be as low as 50% efficient. Electric resistance heaters are usually around 100% efficient at producing heat. However, this statistic is slightly misleading when thinking about total efficiency because you must account for the electric energy being consumed by the heater. Power plants are only able to produce electric energy from natural gas at about 35% efficiency. Consequently, electricity is more expensive than natural gas to produce, making electric resistance heaters more expensive to operate. This energy cost must also be accounted for when adding up the total cost of electric resistance heating.
