GCSE Science Physics (9-1) A guide to the energy of the Earth - Joshua 5 months ago   04:21

You can easily find all the videos that you need on my website, along with other great revision resources. Check it out www.freesciencelessons.co.uk

In this video, we look at the advantages and disadvantages of renewable sources of energy. We explore solar, wind and hydro and then move on to other sources such as geothermal, tidal, wave and biofuels.

I love you

Cool I discovered that my school get your science lessons to teach me

If I watch every single video for biology, chemistry and physics and then do questions, will I know everything I need to know?

i watched this in science ūüôā
honestly this whole energy topic is so depressing there really is no solution we're all going to melt to death hallelujah
Jay Russell
I love this bloke these vids are great haha not

Finally got a new mic

In my biology taster exam, i got one of the lowest grades in the class. I found this on youtube and in my physics I got the highest grade in the class. Thank you Shaun.
Sir I went on the website but it does not work is there anyway I can get the revision guide?
Eliza Mawson
I’ve just got my gcse results and.....I passed! Thank you for helping me do this!!
hollie tube me tube
This was helpful ;)

You have already saved my chemistry paper 1, and you’re about to save my physics. Thank you so much for all of these videos, so to-the-point and easy to follow, and - most importantly - easy to remember.

Much respect and gratitude :)
You rock sir! I like ur videos even before i watch them!!
James Lawrence
I was looking through the spec and I saw that it gave some scenarios for energy transfers on, such as an object hitting an obstacle, in the future could you create diagrams which would help people to understand them? Thanks :) Also, I'm watching all your paper 1 videos again today to revise for the exam tomorrow, they seriously are so much better than the revision guides.
Sarah Rutter
Finished fcs for this playlist WHOOOOO
Thanks again!
Ever since I started to watch your videos, I've been getting better at science. So thank you!
Sakil Patel
very useful
wish you were my teacher

Couldn't you say that hydroelectricity is unreliable in times of droughts? And couldn't you say that wave power is unreliable when the wind drops?
Great video btw
Alex Nicholas
loving the vids! you have helped me get through hard times your vids are so funny and entertaining you look very good in your suit and your hair is very smart

Energy is neither created nor destroyed ‚ÄĒ and yet the global demand for it continues to increase. But where does energy come from, and where does it go? Joshua M. Sneideman examines the many ways in which energy cycles through our planet, from the sun to our food chain to electricity and beyond.
