  • You forgot the biggest problem with solar power sometimes it’s cloudy sometimes it’s dark , therefore you need to be able to store the electricity. Unfortunately we don’t have the battery technology to store electricity on a large scale. Yet

  • This video should have been titled "The Fraud of Solar Panels" as even the video is fraudulent, starting with its opening statements that the reason the number of solar panels are expanding is because of price when it is all political and that fossil energy plants are being forced out of the market because of anything other then government restrictions.

  • My word to 'SOLAR ENERGY " ! No one talk about the millions of butteries we have to replace every 3 to 5 years. Look your car battery lest normal only 5 years But it is only one, Now you have to replace 10 or more will be about 4 to 5000 Dollar with installation. Now you se how much you save . And old batteries polluting the environment more then smoke and oil.

    Bader Al SalehBader Al SalehMåned siden
  • Solar cells are not renewable. It takes far more coal to make each megawatt of solar power than that obtained by simply burning the coal. The same is true with wind turbines. Solar cells and turbines are made with coal power. The whole “green” movement is all about big business screwing the taxpayer. Just ask that idiot Michael Moore, he finally figured it out in his latest book “Planet of the Humans”.

    IichthusIichthusMåned siden
    • That's just blatantly false. There are dozens of papers estimating the resources required to build a wind turbine, even more for solar, and they consistently show that the amount of power that renewables generate far outweigh their material cost.

    David MunroDavid MunroMåned siden
  • Good explanation of the limits and obstacles to higher panel efficiency. But 230,000 MW is not an "astounding figure". This is simply 230 TWh. Meanwhile world electricity production is more than a 25,082 TWh (in 2016). Which means, solar is still less than 1% (in 2019). Not much. Which of course doesn't mean it's efficiency will not increase in importance with time. And the suggestion or hint that solar is responsible for the reduction in coal is a stereotype. An increase of about 0.5% (panels) cannot cause a decrease of about 5%(coal). Actually natural gas is displacing coal. And gas is a hydrocarbon. So please stop the gallumphing.

  • The Power loss of "light induced degradation" will never be completely solved. So, you add the losses together of bad weather, loss of light due to nighttime, and "lid", and you have inefficiencies that make solar unusable to replace Coal, oil, natural gas, hydro, and wind. I have to use coal just to heat my home in the Winter because the other means are too costly. I will not reveal how I obtain the coal. I just get it.

  • Selenium was prevalent in photo-copying machines, that was the sensitive material in the drums. Also, there are still issues with mining & extraction of all these materials for the dubious endeavor of so-called "renewables", along with production, installation, maintenance, operation, deterioration, marketing, logistics, distribution, infra-structure, disposal, waste, & other factors, including research process, often ignored but required in the Life Cycle that transcends & persists for generations. Beside the fundamental energy concerns that are still inherent. Commendable that utmost efficiency is pursued in the lab, but not maintained in field or imposing issues in other areas including harm to people & environment. Beside studying natural phenomena that has achieved efficient effective relationships & fulfilled niche, but people ultimately find ways to foul those relationships & functions, such as exploiting & depleting bio-services, introducing invasives, distortion, contaminated, poison, ... Beside the basic & common ignorance, even smartest people often cleverly deceptive, obfuscate, devious, & self-indulgent of basic vice. My philosophy has determined that there are distinctions between engineering & science. An essential education requires developing critical faculties, exposing logical fallacies, adhering to disciplined experiment method, posing hypotheses & questions, healthy objectivity (absurdly in ScAmerika this is criticized by actual bigots & hypocrites without regard to the ignorance & other consequences) & skepticism, requirement of convincing evidence, rarely settling for an absolute conclusion while becoming disciplined & adhering to a virtuous aesthetic, which are absent among those promoting so-called sustainability development goals, promoting further extraction, damage, excessive consumption, & socio-econ disparity while indulging schemes, scams, injustice, & evading accountability.

  • I had this trouble, also one hot summer and it kills them right off permanently, in 25 years solar panels are pretty much scrap, there will be billions of tons of junk panels in the future, not as green as it seems right now. There is also the fact they are black and don't reflect the suns heat, thus warming the planet, to actually be green you would be better off painting your roof white or silver instead of it being the opposite, some cool the panels with water or float them on water which again retains the heat.

    Andy SmytheAndy SmytheMåned siden
  • What if they could have a small glass of plastic with water in it to lower the heat and use that heated water for hot water use and pump back cold water to cool solar cells. Use the hot water to power a generator.

  • I've seen many agricultural farms turned into solar farms off of land that was originally tilled by hand. Each year crops were grown which supplied food and during the growing season oxygen. The real challenge would be how to remove the greed from those who wan't to be paid for kilowatt hours by depriving the land of food and air.

  • I’m no engineer or scientist, a lot of what is been described in scientific form zooms overhead. What I do understand though, is that we live in very wasteful homes. We block the light coming in by the walls, when if the light was allowed in then it would get warmer, if then the insulating properties were kept, there would be no need for artificially produced energy used for that purpose. I like to see more homes built with that in mind rather than the traditional, wasteful materials and design current. Perhaps we need to educate our children that the homes we are currently living in needs to be radically re-designed for their future needs and enjoyment. We live in a box, a very poorly designed box at that! What’s the saying? Think outside the box?
