Pros and Cons
100
Crops and/or livestock; generates waste pollution
What is agriculture?
100
Primary fuel for electricity generation
What is coal?
100
Uses the Sun's energy directly.
What is solar power?
100
Burning these increases CO2 in the atmosphere.
What are fossil fuels?
100
Pro: safer than tunnel mining. Con: Erosion, habitat destruction.
What is mountaintop removal of coal?
200
Erosion of sand
What is the result of development along coastlines?
200
This fuel can produce energy without polluting the atmosphere like coal does.
What is uranium?
200
Often considered a traditional fuel, this comes from living plant matter.
What is biofuel?
200
Building along these increases erosion.
What are coastlines? (or mountainsides)
200
Pro: Renewable source of energy Con: Not available at night
What is solar energy?
300
Clear-cutting
What is the main cause of deforestation?
300
The most common method of coal mining today.
What is mountaintop removal?
300
Construction of these alternative energy structures caused many to lose their land due to flooding.
What is a hydropower dam?
300
Using sulfuric acid to dissolve and remove Uranium
What is In-situ leaching?
300
Pro: Clean, renewable, compatible with other land uses. Con: Not always available, noisy operation
What is wind power?
400
Landslides
What is a consequence of development along mountainsides?
400
64% of the world's reserves of this are in the Middle East.
What is oil?
400
This fuel is generated from natural gas, but is considered by many to be "the fuel of the future."
What is hydrogen?
400
Fencing, retaining walls and rock bolts.
What are methods of stabilizing mountainsides?
400
Pro:Widely available, renewable Cons: Cost, not a "warm" heat source for home
What is geothermal energy?
500
Heat Islands
What is one consequence of large-scale development?
500
The U.S. has huge reserves of this fossil fuel; mostly in Louisiana.
What is natural gas?
500
Only available near the ocean, this is a VERY reliable source of energy.
What is wave power?
500
Jetties and seawalls.
What are methods of stabilizing coastlines?
500
Pros: Large potential for energy. Cons: Still experimental
What is nuclear fusion?
