geothermal energy
Geothermalenergy
  • Energythatcomes from the beneath the Earth’s surface down where the temperatures are extremely high.
  • It is the heat from the Earth that can be hot water or hot rock.
  • It is found about 3 miles down in the surface.
  • Thisis a renewablesource of energy.
  • Itisfound as thermalenergy.
  • Hot waterorhot rock.
  • In Ecuador we will gather the geothermal energy in Baños near the Tungurahua active volcano.
  • The Earth’s surface is hot making it a good location for the power plant.
history of geothermal energy
History of GeothermalEnergy
  • The first use of geothermal energy occurred more than 10,000 years ago in North America by American Paleo-Indians.
  • People used water from hot springs for cooking, bathing and cleaning.
  • Then in the 18th century people used it more.
  • Now this energy source is not that used.
use around the world
Use aroundtheWorld
  • Geothermal energy is used in the USA in reservoirs of hot water in the western states like Alaska and Hawaii to power up a turbine or generator with the steam of the reservoir.
  • Iceland and New Zealand are using geothermal energy.
  • Geothermal energy produces about 13% of New Zealand's electricity supply.
harnessing the energy source
Harnessingtheenergysource
  • TheenergysourceisfoundinsidetheEarth’ssurface
  • TubespumpcoldwaterintotheEarth.
  • Water comes out as steam.
  • Steammoves turbines thatgenerateelectricity.
  • Toharness/recovertheenergysource, theelectricityisusedtopower up houses.
  • HeatfromtheEarthheatsbathsand pools.
releasing the stored energy
Releasingthestoredenergy
  • The energy is stored inside the Earth’s surface.
  • To released it:
  • Tubes pump in cold water.
  • Water comes out as team into power plants.
  • Steam (thermal energy) moves the turbines (motion)
  • Turbines generate electricity.
advantages and disadvantages
Advantages and disadvantages

Advantages

Disadvantages

Only suitable in places that have hot rocks in the Earth that produce steam for long periods.

Hard to transport.

Not many locations available to use the energy.

Not many locations adapt its use.

  • Saves 80% of costs over fossil fuels.
  • Doesn’t use fuels to create power.
  • Doesn’t release greenhouse gases.
  • Doesn’t make pollution, keeps the environment clean.
  • Safe, clean, simple, reliable and environment friendly.
economic impacts
Economicimpacts
  • Cost of installation f power plant is about 2 billion dollars.
  • The cost of geothermal power is varies and dependent on rock formation geology,depth, temperature.
  • Also water chemistry. site accessibility, and local weather conditions .
  • Cost for the consumer:
  • About 4$ monthly for MW installed.
  • Saves from about 80% of costs over fossil fuels.
environmental impacts
Environmentalimpacts
  • Small amount of posinous gases are releasedtotheatmospherethat are notconsideredto be harmful.
  • Itdoesnot use fuelstocreateenergy.
  • Doesn’t release greenhouse gases.
  • Doesn’t make pollution, keeps the environment clean.
  • Reduces global warming.
  • Safe.
  • Clean.
  • Environment friendly.
future of the energy source
Future of the energy source
  • In theworld:
  • More countries are startingto use itgeothermalenergybecause:
  • Itisrenewable.
  • Doesn’tpollute.
  • Weare hopingthatourcompanygenerates as muchelectricityneeded.
  • Wantittobeused in Ecuador.
  • Manycountries use itforheating and more are startingto.
  • Notmany use itforelectricitybutsomecountrieslike Ecuador are planningtocreatepowerplants.
interesting facts about geothermal energy
Interesting facts about Geothermal energy
  • Geothermal electricity generation is currently used in 24 countries
  • While geothermal heating is used in 70 countries.
  • Geothermal energy uses less than 10 % of the world's energy.
  • It is clean and safe energy for the environment that surround us.
  • Geothermal energy is main energy source in Iceland.
  • Very important and mostly used on volcanic areas.
why is it even necessary for a business to be offering your energy resource at this time
Why is it even necessary for a business to be offering your energy resource at this time?
  • Fossil fuels are nonrenewable so they are running out.
  • Geothermal energy is:
  • Clean.
  • Safe .
  • Does not contribute to pollution (necessary because it reduces global warming).
  • Saves 80% of costs over fossil fuels.
how will your energy source fulfill ecuador s future energy needs
How will your energy source fulfill Ecuador’s future energy needs?
  • Hydroelectric companies generate more than 30% of Ecuador´s energy that vary from 170 MW to 1100 MW approx.
  • We are hoping to generate 250 MW in our geothermal power plant.
  • It will also create jobs for more people.
  • In the future fossil fuel are probably going to run out.
  • Geothermal energy is not a fossil fuel so it is unlikely to run out.
why should your company be chosen over other businesses that utilize different energy sources
Why should your company be chosen over other businesses that utilize different energy sources?
  • Geothermal energy is a renewable source of energy.
  • Not a fossil fuel.
  • Environmentally friendly.
  • Releases almost no poisonous gases.
  • Cheaper than other energy sources.
  • Helps the environment.
  • Our company will be effective.
