​3 requirements:
1. There must be a human demand
2. Must be a physical object and satisfy the demand
3. We must know how to make the object meet the demand

​What is a Natural Resource?

BUT ALSO.....

​It has to naturally
come from the
Earth.

Replenishes faster than its usage. Comes back quickly

​Renewable

Finite amount. Usage is faster the replenishment.

​Nonrenewable

Renewable vs. Nonrenewable

​Is the rate of usage > rate of growth?

​Pros: it's "free" and the direct conversion on energy is non polluting

Cons: when sourcing material to make these panels, we indirectly contribute to emissions and excess sourcing of materials

​

Solar

​Pro: constant and "free"

Con: problematic sourcing of materials, energy storage needs improvement, bird/bat endangerment (collisions and noise pollution)

​​Wind

​Pro: also "free" and water flows constantly

Con: water's path changes, increased soil erosion rate

​​Hydroelectric

Pro: no emissions despite steam.

Con: location is limited (must be in fault or igneous zones)

​​Geothermal

​Pro: waves from the ocean are constant

Con: inadvertently disrupts ecosystem

Ocean Tides

​Pro: we NEVER run out of waste

Con: massive amount of emissions

​​Biomass

​One big nucleus into smaller nuclei.

Fission

​Two smaller nuclei into one larger nucleus.

​​Fusion

• we have nowhere to put nuclear waste (just sits there)

• chance of dangerous fallout events

​Cons

• very little uranium is needed

• considered "cleaner" than conventional fossil fuels

• very efficient energy output

Pros

Nuclear Power....meh.... (as in Mrs. Robbins is conflicted)

• ​PA

• 1979

• cooling malfunction in reactor 2

​​Three mile island

• ​Ukraine

• 1986

• flawed reactor design and untrained staff led to reactor 4 exploding during a test

​​Chernobyl

• ​Okuma, Japan

• 2011

• 15 meter tsunami disabled the cooling system, causing three reactors to explode

​​Fukushima Daiichi
