Energy forms

Work with your neighbor to list as many forms of energy production technologies as you can.

  • Hydro
  • Wind
  • Solar
    • Thermal
    • Photovoltaic
  • Geothermal
  • Tidal, wave
  • Nuclear
    • Fission
    • (Fusion)
  • Combustion
    • Coal
    • Natural gas
    • Biomass
      • biodiesel
      • wood, grass, etc.
      • ethanol
    • Hydrogen

Categorize as renewable or non-renewable

Which ones are the most important?

Guiding principles

The immature human position is that of a child, taking, thoughtlessly, thinking of the Mother Earth as being the all-forgiving, all-abundant, all-giving being that she has been for us. But at some point, if we don’t bring something back to the table, the table will be empty. —Jean Aspen

Energy is all over the news

  • Try it: go to a news site, any news site, and click the search button: “energy”
  • Google “energy” and click on the “News” button.

Video 1

  • Discuss with a group.
    • What do you think about this video?
    • Is it good or bad?
    • What did they get right? Did they misrepresent anything?
      • Won’t need to spend fortunes protecting investments…
      • Trillions of taxpayer dollars are freed up…
      • Smog and greenhouse gases plummet.
      • Public health improves.
      • cooling towers look like they are giving off emissions.

Video 2

  • Discuss with a group.

Energy and standards of living

Energy availability (and technology influencing it, and enabled by it) has increased standards of living, lifespans, reduced poverty, etc.

We would do well to remember this when considering alternative policies and approaches to energy practics and environmental concerns.

Human development index

  • Life expectancy
  • Education
  • Per captia income

What does this plot tell us?

  • HDI is strongly correlated with energy consumption
  • Note the long tail toward the right though.
  • Note the very fast increase with energy on the left.
  • Where is the sweet spot?
  • See also CMO page 238 for some relevant discussion.

Discussion

What are some of the key issues that we will be discussing as we consider energy?

  • Economic considerations
  • Resource limitations
  • Complexity
  • Safety
  • Regional availability
  • Public perception
  • Political interests
  • Historical momentum, existing infrastructure
  • Workforce availability

Values and tradeoffs are the name of the game

  • It’s very easy to be extreme.
    • NIMBY
    • BANANA/CAVE
    • Drill baby Drill
  • Remain open-minded. Avoid uniformed opinions. Wear your thinking cap.
  • As engineers we can develop a much deeper understanding, and informed and nuanced approach to the problem of energy.
    • We can communicate that with others.
    • Opportunity and responsibility.
    • People will trust you because of your degree. Be careful with the trust you are given.
  • There are no simple answers. If there were, we would not be having this discussion.
