Transcript of Geothermal Energy
By: Tamia Phillips,Tiffany Edwards, Wesley Motley
How is Geothermal Energy used to generate power?
Geothermal power plants use steam from water heated underground to spin turbine blades that create electricity.
The history of Geothermal Energy
The first use of geothermal energy occured more than 10,000 years ago in North America by Paleo-Indians.
The first industrial use of geothermal energy began near Pisa, Italy in the later 18th century.
Steam coming from natural vents were used to extract boric acid from the hot pools that are now known as Larderello Fields.
In 1904 Piero Ginori Conti invented the first geothermal eletric power plant in which steam was used to generate power.
Continued History of Geothermal Energy
The first geothermal plant in USA started in 1922.
In 1946 the first ground-source geothermal heat pump was installed at the commonwealth building in Portland, Oregon.
In 1960, pacific gas and electric gas began the first large geothermal power plant in San Francisco.
Geothermal Energy is being used where right now?
Many countries in the world, especially Iceland and New Zealand are using geothermal energy to produce power.
What are the positive benefits of geothermal energy?
Completely clean energy, No emissions or harmful waste, Completely renewable, low cost to operate and maintain.
Efficiency of Geothermal Energy compared to fossil fuels
Geothermal Energy is cleaner, more efficient and more cost-effective than burning fossil fuels and it can reduce our dependence on foreign oil.
Where would be the ideal location to set up a Geothermal company?
Somewhere near the California area. Mexico is #4 on the top ten Geothermal locations and it borders the south side of California.
Is it available in your state?
Yes, it is alternate energy source and is cost effective (in eden).
Is Geothermal energy available in your community?
Yes, geothermal energy is available in my state. It is efficient, cost-effective, and environmentally friendly.
How is the source provided to customers?
The system is installed into homes. Geothermal energy is transported via pipe, as in water to heat your house.
Does Geothermal energy contribute to any form of pollution
Natural features such as hot springs, mud pools, sinter terraces, geyser, and fumaroles and steaming can be easily damaged.
Will it be easy to adjust to?
Geothermal energy is removed through its natural resources.
Can it work forms of energy?
There is so much power that geothermal could power millions of homes.
Geothermal Energy Is The Way To Go!!!!!
Geothermal is the way to go! It is affordable, environment friendly, and efficient. Geothermal energy is very sustainable. Geothermal power has the potential to help mitigate global warming if widely deployed in place of fossil fuels.
How much does it cost?
Getting started with geothermal heat is expensive and is affected by many things: location, house size, and the ground that will have to be drilled. Estimates of actual cost are vague , but it is believed that you can expect the overall start-up cost to be double the cost of a standard heat pump with air conditioner. A geothermal heat pump for average sized house can be roughly estimated to cost around $7,500. You must add the cost of installation to this, which would increase the cost to about $10,000.
What are the negative consequences?
Its not available everywhere. Geothermal heat only works where the earths crust is hot close to the surface. Tends to mostly happen in volcanic regions.
