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.

Our physics teacher is great and gets information across quickly without waffle unlike our chemistry teacher and biology teacher. They made us do pointless tasks instead of teaching the content simply and effectively.

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

Energy is neither created nor destroyed — 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.

Lesson by Joshua M. Sneideman, animation by Marc Christoforidis.
