Fossil Fuels Study Guide

Fossil Fuels Overview

  • Fossil fuels are natural resources formed from the remains of ancient organisms, including plants and animals, over millions of years.

Fossil Fuel Formation

How Coal Was Formed
  • Timeframe: Formation occurred approximately 300 million years ago.
  • Process:
      - Swamp Environment: Before dinosaurs existed, large plants died in swampy regions.
      - Burial Process:
        - Over time, these dead plants became buried under layers of water and dirt.
      - Transformation:
        - Through immense heat and pressure over millions of years, the remains of these dead plants transformed into coal.
Petroleum & Natural Gas Formation
  • Timeframe:
      - Formation occurred between 300-400 million years ago and 50-100 million years ago.
  • Process:
      - Ocean Environment:
        - Tiny sea plants and animals died and were deposited on the ocean floor.
      - Burial Process:
        - Over time, layers of silt and sand covered these organic remains.
      - Transformation:
        - Eventually, through heat and pressure, these organic materials were converted into oil and natural gas.
  • Current Extraction:
      - Today, we drill through layers of sand, silt, and rock to access rock formations rich in oil and gas deposits.

Energy Consumption History

  • Graph Analysis:
      - Energy transitions historically took significant amounts of time to occur:
        - Example: Coal took over 100 years to replace wood.
        - Oil and gas took over 50 years to surpass coal in energy consumption share.

Energy Sources and Consumption Statistics

Regional Consumption by Fuel in 2017
  • Percentage Breakdown:
      - Energy consumption by fuel source varies regionally.
  • Global Consumption Rise:
      - Global energy consumption has averaged a rise of about 2% per year but dipped during the 2009 recession and has increased sluggishly since 2014.
      - Data Source: BP (2018).

U.S. Energy Consumption by Fuel Source (2015)

  • Fuel Source Breakdown:
      - Petroleum (oil): 36%
      - Natural Gas: 29%
      - Coal: 16%
      - Nuclear Electric Power: 9%
      - Renewable Energy: 10%
  • Primary Uses:
      - Petroleum predominately used in transportation.
      - Natural gas, coal, renewable, and nuclear power mainly for electricity generation.
      - Data Source: U.S. Energy Information Administration (2018b).

Global Energy Consumption

Coal and Natural Gas Reserves
  • Countries with Major Coal Reserves:
      - United States: 28%
      - China: 13%
      - Russia: 18%
      - Australia: 9%
      - India: 7%
      - Germany: 5%
  • Combined Reserves:
      - The six mentioned countries account for 80% of the global recoverable coal reserves.
      - Reference: Adapted from US Energy Information Administration (2011).
U.S. Coal Production Trends (1950-2019)
  • Production Data:
      - Significant fluctuations noted:
        - National coal miners' strike in 1978 and producers reaching peak levels in 2008.
        - Declines observed in recent years, noted as the lowest output since 1978.

Oil Production Overview
  • Largest Proven Oil Reserves (in billions of barrels):
      - Venezuela: 300.9
      - Saudi Arabia: 266.5
      - Canada: 169.7
      - Iraq: 142.5
      - Kuwait: 101.5
      - Russia: 80.0
      - U.S.: 36.5

Bakken Formation Oil Boom
  • Impact of Hydraulic Fracturing:
      - The Bakken Oil Formation underwent significant production growth in the early 2000s due to advancements in hydraulic fracturing technology (fracking).
      - By 2014, North Dakota and Montana states produced 1 million barrels of oil per day, contributing to 10% of U.S. oil production.
Natural Gas Production Trends
  • U.S. Natural Gas Gross Withdrawals:
      - Recorded in million cubic feet over the decades.
      - Trend: Continuous increase noted in production from 1940 onwards.

Environmental Impact of Fossil Fuels

  • Air Pollution from Coal and Natural Gas:
      - Emissions rates are critically analyzed for carbon dioxide, nitrogen oxides, and sulfur dioxide.
      - Data Representation: Rates are expressed in tons per megawatt-hour and pounds per megawatt-hour, highlighting the ecological impact of fossil fuels.

Externalities Related to Fossil Fuels
  • Environmental and Health Issues:
      - Considering oil spills, pipeline leaks, habitat loss, air pollution, health impacts, and geopolitics as external factors resulting from fossil fuel extraction and consumption.

Questions to Ponder

  • Where do fossil fuels come from?
  • Why is there a decline in coal production?
  • What is fracking and how does it impact natural gas production?
