Water and carbon dioxide
This is the #1 global source of electricity production
Coal
Coal is ~___% efficient as a fuel source for generating electricity
30
Coal combustion releases more what than any other FF when burned for electricity generation:
CO2
This type of FF is extracted by drilling a well through the overlying rock layers to reach the underground deposit and then pumping liquid oil out under pressure
Oil or petroleum
Combustion is a step in this cycle
Carbon cycle
The steps of electricity generation are the same, no matter what you’re burning to produce the initial heat. What is the first step after the production of heat?
Water turns to steam
Natural gas is ~____% efficient when it’s burned to generate electricity
60
What product of burning coal irritates the respiratory tracts of humans/animals?
particulate matter (PM) (soot, ash) sulfur and nitrogen oxides
This is a term for an area thats a combination of clay, sand, water, and bitumen, from which oil can be extracted.
Tar sands
This is the chemical name for natural gas. The chemical formula is CH4
Methane
The steps of electricity generation are the same, no matter what you’re burning to produce the initial heat. What is the second step?
Steam turns a turbine
Much of the energy “lost” or not converted into electricity escapes as what?
Heat or thermal energy
Which type of FF extraction was responsible for the Deep Horizon disaster?
This is a term used to describe the extraction of natural gas from sedimentary rock
Fracking
These are the reactants of combustion
Oxygen and a hydrocarbon
The steps of electricity generation are the same, no matter what you’re burning to produce the initial heat. What is the third step?
The turbine powers a generator.
This is the term for when the heat produced from electricity generation is used to provide heat (air & hot water) to a building
Which type of extraction has a link to increased seismic activity (earthquakes)?
Fracking
This material (made of water, salt, detergents, acids) is pumped into well @ very high pressure to crack the rock even more & allow natural gas to flow out.
Fracking fluid
What form of energy is released by the combustion of fossil fuels
Heat (thermal energy)
The steps of electricity generation are the same, no matter what you’re burning to produce the initial heat. What is the fourth and final step?
Generator produced electricity
These types of systems are close to 90% efficient, which is much better than coal or natural gas alone
CHP (Combined Heat and Power)
This is a consequence of ALL types of extraction methods discussed.
This material (used fracking fluid) flows back out well and is collected and stored in containers or ponds nearby
Flowback water
