Renewable Energy


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.

    I'm taking a training course in solar panel installation, repair and maintenance. My instructor recommended this book [link here >>> ] as an excellent resource along with the course. I'm finding it invaluable. By buying it through Amazon, I saved considerable money and received it very quickly.

    My power bill was $300 this previous month. It seemed absurd to me that it would reach this high. Something had to be done. With the generating power method “boma fetching unique” (Google it), my electric bill is now diminished by around 60% because I was able to produce power, also. And that`s not just temporarily-that`s forever.

    There should be no difficulty in trying to decrease your utility bill. In fact, it’s the easy options we make which could have a biggest impact. By using this generating power technique “boma fetching unique” (Google it), you can make your own power and save cash on bills.

    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?

    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

    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.
