LECTURE 1INTRODUCTION

Dr. Rostamkolai

ECE 371

Sustainable Energy Systems


Human ecology

HUMAN ECOLOGY

  • There have been 3 constants in recorded history of humans

    • Living together in a clean and safe environment

    • Searching for useful energy

    • Developing better ways to obtain the supply of energy to make life safer and more comfortable (irreversible path)


Human ecology1

HUMAN ECOLOGY

  • Therefore

    • For any growth rate, energy consumption will grow at a greater rate

    • Unless a more useful higher-specific-energy source than nuclear fission is discovered, nuclear energy will eventually become the preferred energy source

    • Issues with the dangers of nuclear power has forced humans to search for alternative sources of energy for the time being


Human ecology2

HUMAN ECOLOGY

  • United Nations compiled data shows the world population growth from 0 A.D. to 2050


Human ecology3

HUMAN ECOLOGY

  • UN projection shows a decline in annual incremental growth


Human ecology4

HUMAN ECOLOGY

  • Also, UN compiled data on energy consumption


Human ecology5

HUMAN ECOLOGY

  • The following table shows the world’s energy consumption per capita for the past 100 years

    Quads = 1 x 1015 BTU BTU = 2.928 x 10-4 kWh

HUMAN ECOLOGY

  • The next table shows the Carbon/Hydrogen (C/H) ratio for rapid changes in preferred fuels


Human ecology7

HUMAN ECOLOGY

  • The specific energy of fuel, which is defined as the amount energy available from a fuel per unit amount of mass (e.g., kJ/kg) is an indicator of ease of using a particular fuel

  • Where,

    • H2 – Chem: Chemical Hydrogen

    • Uranium: Nuclear Fission

    • (d,t) Nuc: Thermonuclear Fusion

      (Hydrogen Bomb – Not civilian power)


Human ecology9

HUMAN ECOLOGY

  • The interrelationship between economic development, food and energy resources, and environmental impacts raises the concern about the world survival


Human ecology10

HUMAN ECOLOGY

  • Three major problems threatening the world survival are

HUMAN ECOLOGY

  • In conclusion

    • Continued growth in human population with

      greater growth in energy demand may not be

      sustainable far into the future
