7.1: Fossil fuels
Natural Gases
mixture of methane, propane and butane, and hydrogen sulfide
-
-
-
Advantages: Cheaper to extract, plants to process gases are less expensive and take less time to build, cleaner than oil and coal
Disadvantages: low price can slow down the shift in reliance on renewable, clean energy.
drilling, production, and distribution process for natural gas leaks large quantities of methane into the atmostphere
requires huge inputs of energy
risk of grounwater pollution
Coal
-
-
remains from plants that were buried and expose to intense heat and pressure for 300-400 million years
Extremely inefficient production of electricity using coal (65% of the energy released is wasted into heat)
Disadvatages: -largest emitters of CO2
-Mining the coal severely degrades land
- extreme air pollution that leads to roughly 683K deaths a year in just the USA and China
- pollutes lakes and can contaminate birds and fish
Coal Ash: product from the process of cleaning the coal before being released into the atmosphere which contains indestructible, dangerous chemical elements.
It is not categorized properly and can be legally treated as household garbage
