Energy Flashcards
Transformation of energy is not 100% efficient
2nd law of thermodynamics
Energy is neither created nor destroyed, it can only be transformed
1st law of thermodynamics
Energy stored with zero or a minute rate of replenishment relative to its depletion by human beings
Non renewable energy sources
Types of natural energy that are replenished by natural flux within the time frame of conceivable human use
Renewable energy sources
4 types of non renewable energy sources
Fossil fuels
- Coal
- Oil
- Natural gas
Not a fossil fuel: 4. Nuclear energy
Most abundant fossil fuel resource
Coal
Types of coal
Peat, lignite, bituminous coal, anthracite
Not a coal; from decayed plant matter in swamps, low heat content
Peat
Brown coal; low sulfur content, limited supplies in most areas, low heat content
Lignite
Soft coal; extensively used, large supplies, high sulfur content, high heat content
Bituminous coal
Hard coal; highly desirable fuel, low sulfur content, limited in most areas, high heat content
Anthracite
Coal mine in the philippines
Panian, antiquie
Types of oil (from increasing heat content)
CRUDE OIL —> Asphalt, naptha grease and wax, diesel, heating oil, aviation fuel, gasoline, gas
Has 63.3% of the world’s oil
Middle east
Made up of 50-90% methane
Natural gas
