New renewable energy sources - Algae to biofuel!

 ESO1 students. We've been talking about algae in the class this week. This is a really interesting video you can watch. It's about how you can obtain an efficient biofuel from algae. If you would like to do a topic on this for extra marks you can write the main points discussed in this documentary. Make sure you focus on the interesting facts and information explained in the video.

 ESO 2 students. We have often talked about energy sources in the science class. We have mentioned how non-renewable energy sources are quickly disappearing and how important it is to find new clean, renewable energy sources. This is a surprising and interesting way of obtaining a sustainable and relatively cheap biofuel. You can do a topic based on this video in which you can explain the process by which this fuel is obtained, what natural chemical processes are involved and why it's such a cheap, efficient energy source. Why is this biomass good to use for biofuel? What are the advantages? Is it similar to petrol? Are there any disadvantages? Can this biofuel substitute petrol? It's always interesting when you add a personal opinion to your project.

 This video is interesting too!
