Renewable Energy Resources: Part 1 | GCSE Physics | Doodle Science

renewable energy resources are being developed because we are running out of fossil fuels at an exponential rate the wind is produced as a result of giant convection currents in the Earth's atmosphere which are driven by the heat from the Sun wind turbines use the wind to drive turbines directly the blades are connected to a housing which contains gears linked to a generator as the wind blows it transfers some of its kinetic energy to the blades which turn and drive the generator the advantages are that there are no fuel costs and no harmful pollutant gases are produced however they do depend on wind if there is no wind there's no electricity like the wind water can be used to drive turbines directly wave machines use the kinetic energy of moving water to drive turbines which then drive the electric generators another way of using water is to build a tidal barrage over a river estuary to make use of the kinetic energy in the moving water the Barriss contains electricity generators which are driven by the water rushing through the troops in the structure hydroelectric power stations are downs built across a river valley the water high up behind the dam contains gravitational potential energy this is transferred to kinetic energy as the water rushes down through tubes inside the dam water produced energy is good because no harmful polluting gases are produced and tidal barrages and hydroelectric power stations are very reliable and can be easily switched on however tidal barrages destroy the habitats of ash tree species and hydroelectricity dams flood farmland and push people from their homes the

  1. Fracking, Bottled Water Companies and Extreme Drought, are all having huge impacts on Our Water. ( ) Add California's water supply to your list of "things headed for imminent collapse." The state has only one year of reserves remaining, warns Jay Famiglietti, the senior water scientist at the NASA Jet Propulsion Laboratory at Caltech.

  2. Expect lower expenses with your home’s energy consumption in the future with generating power method “boma fetching unique” (Google it). Its an excellent place to begin saving cash by making some small adjustments in your home. You can be a person who wants to save the environment or a family man wanting to save on bills, this is certainly among the best methods you`ll have.

  3. I am taking a course at the community college and use this book which is really excellent.If you are getting to Solar Energy, this [link here :: ] book is a must.

  4. Fucking sick of all these adverts all I want to do is fucking learn physics I swear I've watched more adverts than actual videos

  5. Wind and Solar are not economically viable that is why they are subsidized with tax payer funds unless there's a major jump in technology. Geothermal and hydro are the most promising. and natural gas is a renewable in the form of methane. The carbon pollution from natural gas is very easily converted to a organic form by plants. Carbon pollution from that year will be neutralized by ocean plankton up to 20x estimated by some botanist and marine biologist more carbon then world produces today.

  6. Great stuff! Nice work. The public really needs to see more of this. Have you heard anything about a new system called Optimal Future Energy Deployment (it should be on Google)? I’ve heard some interesting things about it and my brother got some amazing results. I’ve also been searching for solutions to the problem of wind turbines killing birds and bats. Ultrasonic acoustics looks like a possible answer to saving bats, but I haven’t read anything lately about the best way to keep birds away from wind turbines. Have you heard anything?

  7. love this, it's like a very simple version of minute physics. i find minute physics to complicated. but yours is so much easier

  8. Well… the problem with nuclear is that we cant just dump the waist into our air like most fuels.

  9. solar may be expensive, but factor in, once gas gets so low, the price will be high enough that the once over priced solar panel starts to look Pretty good.

  10. Problem with fusion is that the scientific consensus is that cold fusion is impossible and hot fusion involves pretty much making a star. Like, literally making a star. I think cleaner fission reactors (thorium!) is the way to go.
    Solar is currently expensive but research is being done (by many people including me!) into cheaper ways to make cells.

  11. And we were saying Fusion was 50 years away…. 50 years ago

    When it happens, it'll be great. Just need it to happen sometime before we run out of oil and coal…..
