Origins & Politics
a combustible black or dark brown rock consisting mainly of carbonized plant matter, found mainly in underground deposits and widely used as fuel.
What is Coal?
How many steps does producing Coal energy take?
What is 4 Steps?
powdered Coal is burned
Water is turned into steam
Steam turns the Turbine
Steam returns to water through condensation
Name 2 Cons of Coal
What is
1.Greenhouse gas Emissions
2.Tons of waste
3. Mining Destruction
How much does Coal cost per Watt?
what is $.00007 per watt or 7 cents per kWh
What are some environmental damages caused by coal?
What is coal contains carbon, and when carbon is burned it pollutes the air, mining destruction
When was Coal founded/Discovered?
What is 19th Century?
The burning of coal to generate electricity is a relative newcomer in the long history of this fossil fuel. It was in the 1880s when coal was first used to generate electricity for homes and factories.
How many Steps does Geothermal Energy need to be produced
What is 3 Steps?
Hot Water is pumped up is relived of pressure and becomes steam
Steam turns a turbine Producing electricity
Water is cooled and returned to the Earth
Name 2 of the Pros of Coal as an energy source.
What is
1.Reliability
2.Affordability
3.Abundance
4.Safety
How much does Geothermal energy cost per Watt?
What is $.00003 or 3 cents per kWh?
What are some environmental damages caused by geothermal energy?
What is there is minimal damage caused to produce geothermal energy, because the only emissions produced is steam
Geothermal energy was founded in what century?
What is the 20th Century?
(In 1904, Italian scientist Piero Ginori Conti invented the first geothermal electric power plant in which steam was used to generate the power.)
How many years at current production can we keep using coal?
What is 150 years?
There are 1.1 trillion tons of Coal left that we know of.
Name 2 PRO's of Geothermal Energy
What is
1. Small Footprint on Land
2. Great for heating and Cooling
3. Available everywhere
4. Naturally replinished
How much $$$ does it take to create a Coal Plant?
What is 2 Billion $$$$!!!
(A new MW Coal Plant)
Which energy source - coal or geothermal energy has less environmental damage?
What is geothermal
Heat from the Earth used to provide energy?
What is Geothermal Energy
How long can we use Geothermal energy before we run out?
What is as long as the earth is intact?
The ground is warmer due to the mantle in the earth.
Name 2 CON's of Geothermal energy
what is
1.Cause earthquakes (rarely)
2. Expensive
3.Sustainability issues with reservoir
4. Environmental issues with Sulfur dioxide
How much money does it cost to make a Geothermal Power Plant?
What is 340,000$ for a small power plant capable of 100 kWh.
What is the Financial "risk" for coal consumption
What is a decrease in supply leading to increasing prices.
Why is geothermal a "dangerous" energy source
What is, very rarely on large scale geothermal plants, can the earth's crust be disturbed and create very small tremors due to the unsettled soil.
Why is Geothermal resourcefully better than Coal energy?
What is, Geothermal does not use any resources up. It simply pumps water to create electricity.
What state is the largest Coal reserve
What is Montana?
After 1 year, which is cheaper Coal or Geothermal to heat and cool your house.
What is Coal is cheaper because setting up a geothermal system in a house costs a lot of money to make but is very cheap to use.
How can geothermal energy "risk" some areas
What is Geothermal plants are sited on geological “hot spots," which tend to have higher levels of earthquake risk. There is evidence that hydrothermal plants can lead to an even greater earthquake frequency [9]. Enhanced geothermal systems (hot dry rock) can also increase the risk of small earthquakes.
