028 – Renewable Energy

In this video Paul Andersen discusses the technology, advantages and disadvantages of six sources of renewable energy; biomass, hydroelectric, solar, geothermal wind, and hydrogen. He also explains how changes in the storage and flow of energy in our power grid must be improved. He also lists the energy returned over energy invested ration for the various forms of energy.

  1. Binge watching all your videos for tomorrow's AP Environmental Science Exam at 8 AM, Wooooo, so excited 🙁 Hope the exam goes well, also great work on these videos Mr. Anderson.

  2. Well produced videos. But as a teacher in physics I dare not use them to educate my pupils, since the errors are to big and they will be misled. Start by fixing:

    Error 1: Watts is not a measure of energy. TWh, kWh and J are common measures of energy though. What did you really mean with your numbers?

  3. Your vids are so damn boring… 😴😴 we watch you in science class and I can't make it through half of your video without falling asleep 😴 do something to make it more fun so I can actually learn thanks

  4. CO2 leading global warming?
    You just lost your science degree..!

    Biomass is a total loser as burning food and using perfectly good farmland for energy while millions are starving is madness.
    Solar and wind have one big failure as they are dependent on weather. Wind is even more landscape destructive and enormously expensive.
    Its all about energy density, nothing will beat liquid fuels and thorium power in the end.

  5. You win best teaching graphics of the year. The whole thing was pretty engaging, kudos

  6. And of course the first problem of the equation is…PROFIT MOTIVE.

    We need to change our fundamental way of recourse distribution and thinking.
    -The world should be run by science, technology, and intrinsic motivation.
    -The world should NOT be run by a labor system for profit/survival (especially in light of machine automation and cybernetics), Profit motive that leads to social inequality and a lot of crime, and a "democratic" government that is actually run by corporate interest as a result of fiat monetary corruption.

    Monetary trade is a corrupt system that generates corrupt behavior, and this in turn is the source of almost all structural violence in the world. Plain and simple.

    A return ratio of 1.3:1 is more than acceptable. Anything with a positive ratio is fine as long as it's renewable…The point is that it returns more than we put in. And over time, it will only get better. In todays world, we're looking at it from a monetary profit perspective, not an efficiency and symbiotic perspective.

    Great video. Thank you 🙂 I just had to rant.
