    The Earth intercepts a lot of solar power: 173,000 terawatts. That’s 10,000 times more power than the planet’s population uses. So is it possible that one day the world could be completely reliant on solar energy? Richard Komp examines how solar panels convert solar energy to electrical energy.

    We do not need deserts in order to get solar power. Put solar arrays above car parking lots. The United States has 24,000+ square miles of parking lots. Bonus; you get to park in the shade.

    There is a "typo" in 1:22. While it is correct that N-type material has more electron and P-type material has more holes, they are by themselves neutral. When we put the N and P type silicon together, electrons in the N material tend to travel across the junction and occupy the holes in the P material, which leads to positively charged N-type semiconductor on the top and negatively charged P-type semiconductor at the bottom (according to the video). Thus the "+" sign should be on top and the "-" sign should be at the bottom.

      It is not exactly what powers a solar cell, that would be the photovoltaic effect, but they are very closely related, and in principle, acts the same way; A photon interacts with an electron, and thereby makes it emit the electron, which results in a direct energy transfer from light into electricity.

      But i think the credit is due to the early discoverers, as Solar panels and spectroscopy, among other things, wouldn't be possible, hadn't the interaction and correlation between light and excitation of electrons been discovered.

    I've recently become a huge proponent of portable solar panels. They're a good transition to full-scale solar to prove the concept on a small scale that can be scaled up later. I have four portable panels and some power banks, and take them everywhere to show them off and get people hooked on solar, especially skeptics who want to see it for themselves before making n'y decisions. It's great!

    • @sampleoffers1978
      @sampleoffers1978 Před rokem

      They need to be able to make the light the panels absorb...either without heat, or heat that powers magnetism enough to suspend light over the panel....Lenses can magnify light, and spectrums can be duplicated...Panels should usable indoors and stacked up...not chasing the sun, needs to be the evolution. Glowing tee shirts convince me light can be harnessed for closed system panels, probably from chemically or magnetically treated particles.

    • @astikrasgabas
      @astikrasgabas Před 4 lety +5

      @@genericasianperson6405 The year that you start to profit from pv panels depend by the country and the climate. E.g. it will take longer to start making profit in Germany because electricity is more expensive as they tend to use more green energy compared to something like France as a lot of their energy is nuclear which is dirt cheap, and by climate especially during winter as the pv panels tend to be covered by snow especially in North regions. In winter you will tend to use more energy than what pv panels can produce.

      No we need sustainable energy. The population at present and the growth of the population will deem renewable energy such as wind and solar insufficient. For personal use such as cars, homes and private businesses yes it will work. But as the sole power source is absurd and will result in blackouts due to insufficient supply to demand. We need fusion energy, we are focusing too much resources to the wrong area.

      Well I have built many Data Centers. We don't depend on utility electricity. We always have an UPS to backup electricity failure and right after that we have a Generator to power up within minutes. I have a site where we purchased 1000 liter fuel for Generator 6 years back. But used as little as 80 liters in these years. But preventive maintenance of Generator n UPS is done monthly.
      So we will have utility power as backup, or maybe for nights. This way we can at least slash down electricity bill to 1/3 for individuals. This may reduce the fossil fuel usage by utility companies.
      First thing mentioned in this video, the political reasons and businesses who take profits by selling power is the main reason.
